lizard-map 5.2

Basic map setup for lizard web sites

lizard-map
==========

Lizard-map provides basic map interaction for `Django
<http: www.djangoproject.com="">`_ applications that use a `lizard-ui
<http: pypi.python.org="" pypi="" lizard-ui="">`_ user interface. We designed it at
`Nelen & Schuurmans <http: www.nelen-schuurmans.nl="">`_ for our geographical
information websites (with water management information).

It provides:

- Openlayers (map javascript libary) map display and server-side map
generation (mapnik's WMS functionality). Background maps are configurable.

- A "workspace" interaction model: drag mappable items into a workspace and
they'll get displayed. The workspace is stored in the Django database.

- A "collage" attached to every workspace for storing selected info on map
items (like graphs).

- An extention mechanism to plug more or less arbitrary map sources into the
workspace so that they can be displayed, searched, etc.

Core concept: workspaces
------------------------

A *workspace item* is something that can be displayed on a map. A *workspace*
is a collection of workspace items that is actually displayed.

There are two types of workspaces:

- Edit Workspace: Every session/user gets its own workspace. This
workspace can be edited.

- Storage Workspace. TODO: extra info.


A workspace item needs to know how to display itself, how to search for items
when you click on the map and more. To get that to work for arbitrary map
sources, you need to configure an adapter. The adapter has a ``layer()``
method for returning a mapnik layer, a ``search()`` method for searching and
so on.

- You register an adapter as a so-called "setuptools entrypoint" under a
specfic name.

- When you add a workspace item, you pass in the adapter name and an optional
snippet of json to configure the adapter.

The workspace item keeps track of this adapter and its configuragion and uses
it to generate maps, for searching, etc.


Collages
--------

A workspace item often results in multiple areas or points. If you click on
such a point, you normally get a popup with extra information. If you want to
compare a couple of those information "snippets", you can place them in your
*collage*. In the GUI this is called "Selectie".

Clicking the collage gives a popup with all the collected information popups
in that single popup.


Interaction
-----------

Included is quite some javascript for workspace interaction. Potential
workspace items can be drag/dropped into a workspace to add them. Workspace
items can be reordered. You can drag them to the trash.


Dependencies
------------

Almost all dependencies are listed in our ``setup.py``, so they get pulled in
automatically. Not all of them install as good as eggs, though. You might be
better off installing them system-wide with your OS's own packaging system.

You can force buildout to use system-wide installed packages with the
`osc.recipe.sysegg <http: pypi.python.org="" pypi="" osc.recipe.sysegg="">`_ recipe.
An example config::

[buildout]
...
parts =
sysegg
...

[sysegg]
recipe = osc.recipe.sysegg
force-sysegg = true
eggs =
PIL
matplotlib
simplejson
pyproj


Development installation
------------------------

The first time, you'll have to run the "bootstrap" script to set up setuptools
and buildout::

$> python bootstrap.py

And then run buildout to set everything up::

$> bin/buildout

(On windows it is called ``bin\buildout.exe``).

You'll have to re-run buildout when you or someone else made a change in
``setup.py`` or ``buildout.cfg``.

The current package is installed as a "development package", so
changes in .py files are automatically available (just like with ``python
setup.py develop``).

If you want to use trunk checkouts of other packages (instead of released
versions), add them as an "svn external" in the ``local_checkouts/`` directory
and add them to the ``develop =`` list in buildout.cfg.

Tests can always be run with ``bin/test`` or ``bin\test.exe``.


External dependencies
---------------------

The dependencies for a full website that uses lizard-map are best expressed as
ubuntu/debian package dependencies: build-essential, python2.6-dev, apache2,
libjpeg-dev, python-imaging, python-matplotlib, python-mapnik, python-scipy,
libapache2-mod-wsgi, python-gdal, spatialite-bin, python-pysqlite2,
python-pyproj.


Upgrading to Lizard 3
---------------------

Short summary to convert your app to Lizard 3.

- Replace old template tags workspace with workspace_edit and
collage_edit (see below).

- Review urls.py for old lizard_map views. Replace with new ones or
remove.

- Migrate

- Upgrade to class-based views, using one of the View classes
(i.e. AppView). An excellent description can be found when googling
"class based views reinout". You can take lizard-map views as
examples as well.


Site integration
----------------

The following steps has to be done in order to use the
lizard_map/workspace concepts.

- Install lizard-map somewhere. (Add 'lizard-map' in your setup.py:
install_requires)

- Add 'lizard_map' to your settings.py: INSTALLED_APPS.

- Add an entry in your urls.py::

import lizard_map.urls

(r'^map/', include(lizard_map.urls)),

- Use one of the views, i.e. AppView.


Example view::

from lizard_map.views import AppView

class MyAppView(AppView):
template_name = 'my_app/template.html'


Example template::

{% extends "lizard_map/wms.html" %}
{% load workspaces %}

{% block subtitle %} (page name) {% endblock %}

{% block sidebar %}

<div id="iconbox" class="sidebarbox sidebarbox-stretched iconlist">
<h2>Apps</h2>
<ul>
<li>
<a href="/address/" class="lizard-map-link">
<img src="{{ STATIC_URL }}lizard_ui/app_icons/meetgegevens.png"/>
<div>App</div>
</a>
</li>
</ul>
</div>

{% workspace_edit view.workspace_edit %}
{% collage_edit view.collage_edit %}

{% endblock %}

- Add this view to your url.py:

import my_app.views

(r'^$', my_app.views.MyAppView.as_view()),


- Start testing by running syncdb / migrate.

- Add and configure background maps by loading "background_maps" fixture.

- Start dev server.


Settings
--------

Some default date range settings can be set in settings.py. All
settings are optional::

START_YEAR = 2000 # Defaults to today - 7 years
END_YEAR = 2010 # Defaults to today + 3 years.

# Define default period 1..5
# From daterange.py:
# PERIOD_DAY = 1
# PERIOD_TWO_DAYS = 2
# PERIOD_WEEK = 3
# PERIOD_MONTH = 4
# PERIOD_YEAR = 5
# PERIOD_OTHER = 6

DEFAULT_PERIOD = 5 # Defaults to 1

# If DEFAULT_PERIOD = 6, define these
DEFAULT_START_DAYS = -20 # Defaults to -1000
DEFAULT_END_DAYS = 1 # Defaults to 10

You can add google analytics to your site by adding the tracking
code::

GOOGLE_TRACKING_CODE = 'AA-12345678-0'

Changelog of lizard-map
=======================

5.2 (2015-01-15)
----------------

- Remove defaults from JSONFields in old migrations. The default
default (dict) is fine, and incorrect defaults caused some
migrations to fail.


5.1 (2014-12-15)
----------------

- Upped lizard-ui requirement.


5.0 (2014-12-15)
----------------

- You can now save the dashboard just like you could already save the
workspace. They're not shown on the homepage, though. If needed you
can add an app icon for that.

- You can add a ``disclaimer_text`` setting in the admin now. This is copied
verbatim to the first window of the on-screen tour. So don't put html tags
in here.

- Removed pan-to-click-location, it is simply to obtrusive.

- The display-name-while-hovering-over-the-map functionality now only searches
in the first layer (=workspace item), not in all of them. This way, it is
more predictable which results you get.

- Removed 'week' from the period selection. 'Week+1' is now called 'week', but
retained the week+1 functionality. Added 'halfyear' option.

- Using 'orangered'instead of yellow in the graphs as HHNK wants that.

- Added lizard-security to WorkspaceStorage: this allows you to effectively
filter the start page.

- Set workspace on default as private.

- Fix grammatical mistakes in info-tour.

- Move to Lizard 5.

- Add `private` flag to WorkspaceStorage model. If a WorkspaceStorage
instance is labelled private, it is not shown to anonymous users.

- Migrated to mapnik 2.2.0.

- Added action for elevationprofile

- Update translations.

- Removed console.log statements. IE hangs with them.

- Make two untranslated strings translatable.

- Update source language (english) django.po

- Add Box awesome.

- Add support for correct getFeatureInfo for lizard wms.

- Reintroduced workspace save icon (admin only).

- Remove animatable.

- Add WMS filter on the page.

- Fix bug where IE9 couldn't use the search bar; we should use JSONP
for cross-site requests.

- Re-added collage screen (called "Dashboard" now), mostly by re-enabling old
functionality. Bigger change is the layout of the actual main collage page:
the labels and so are now next to the graphs as there's no separate sidebar
anymore.

- Fix timezones once more.

- Fix text, layout and z-iondex positions of info tour wizard.

- Hiding rainapp's period summary on the collage screen.

- Opening dashboard/collage in new tab.

- UI updates for the dashboard page.

- Remove coordinates.DEFAULT_MAP_SETTINGS (unused since 2011), move default
map code from views.py and coordinates.py into models.BackgroundMap.

- Move settings and their defaults to conf.py (using django-appconf).

- The Setting model's .get() and .extent() functions now don't take a
default anymore, rather if a Setting isn't found they get their
defaults from normal Django settings -- a setting called "mysetting"
uses the LIZARD_MAP_DEFAULT_MYSETTING_SETTING setting. Setting
setting setting.

- Several defaults were updated to what lizard5-site sets in its
base.py, so the settings can be removed there. No other settings
were actually set in lizard5-site, so how configurable do these
things need to be?

- Added reloading of graphs upon flot pan/zoom. The
according-to-the-manual-zoom start/end date is passed in the normal way to
the backend: no changes necesseary. This is expensive, though, so the
backend *must* add an extra ``.dynamic-graph-zoomable`` class in addition to
the current ``.dynamic-graph`` class.

- Made the interaction with graphs that fail to load nicer.

- View state persists also on the dashboard page now.

- Added 'please log in' hint when there are no visible workspace storages.

- The 'default_range_type' Setting can now be set to override the
default date range. Possible values are 'today', '2_day', 'week',
'week_plus_one' (default), 'month' and 'year'.

- Use the function values_multiple_timeseries() to export timeseries from
lizard-fancylayers adapter.

- Add LanguageView to setup a different language per site.

- Create LocaleFromSettingMiddleware to use language_code from Setting models.

4.28 (2013-05-06)
-----------------

- Added a completely transparant icon, ghost.png, for layers that
shouldn't be shown but for which the popup should still work.

- Some changes to be iPad friendly were made.

- The small layerswitcher is moved to the upper bar for easier use.

- The left hand zoom in and out buttons are not shown on iPad.

- 'Zoom to start location' is now just an icon.


4.27 (2013-04-03)
-----------------

- Fixed tab_titles being undefined when a popup of collage items is
opened.

- Merged functionality from the deltaportaal lizard-map branch:

- Showing metadata at the bottom of the regular description popup. The popup
is now an 'i' you should click instead of an on-hover dialog. Works better
with an ipad. Note that there's now a ``lizard_map.css`` again.

- CQL filtering is possible on featureinfo items on wms layers.

- Popups opened from the sidebar now disappear when the sidebar scrolls. No
more zombie popups.


4.26 (2013-03-20)
-----------------

- Tabs in the popup now, by default, get the name of the first workspace item
whose result is shown. This is waaaaay nicer than "tab 1, tab 2, tab 3".


4.25.6 (2013-03-13)
-------------------

- Fixed IE7 error caused by extraneous comma in animations.js.


4.25.5 (2013-02-27)
-------------------

- Haastige spoed...


4.25.4 (2013-02-27)
-------------------

- Default number of frames in animation set to 720.


4.25.3 (2013-02-27)
-------------------

- Changed animation speed from 500ms to 1000ms per frame.


4.25.2 (2013-02-27)
-------------------

- Moved animations.js import again.


4.25.1 (2013-02-27)
-------------------

- Changed animations.js import order (caused error).


4.25 (2013-02-26)
-----------------

- The change described in 4.24 didn't really work well, because the
session object wasn't created yet when the default workspace was
copied. This is fixed.

- Removed hour / day clamping (rounding) in the daterangepicker. Values for
dt_start and dt_end are now simply a relative period based on the current
time.


4.24 (2013-02-25)
-----------------

- It is now possible to use some stored workspace as a "default
workspace" for users who get a newly created workspace.

If the Setting 'default_workspace_anonymous_user' exists and is the
secret slug of some existing stored workspace, then the items in it
will be copied to any anonymous user's workspace when it is first
created.

The same holds for 'default_workspace_user' and logged in users,
although it is probably less useful for them since their workspace
is only initially created once, after that they keep using their
existing one.


4.23 (2013-02-19)
-----------------

- Add vietnamese translations for month names via google translate.

- Remove zc.buildout >= 2.0.1 from setup.py since it is not a dependency.


4.22 (2013-02-19)
-----------------

- Added animation support for wms urls that have 'time' in them. Includes
backbone 0.9.10, underscore 1.4.4.


4.21 (2013-02-19)
-----------------

- Manage translation strings with Transifex. Update en (source) and nl
translations. Use nens/translations package for this.

- Add vietnamese django.po file from Transifex.

- Upgrade to zc.buildout 2.0.1.


4.20 (2013-01-22)
-----------------

- Fix context instance instantiation in html_default method.


4.19 (2013-01-21)
-----------------

- Add RequestContext instance when rendering a template in html_default
method. This way request-related tags and context variables can be
used when rendering the template.


4.18 (2013-01-17)
-----------------

- Adjust FlotGraphAxes to enable threshold lines.
- PEP8 fixes.

4.17 (2013-01-10)
-----------------

- Fix timezone handling for Flot graphs.

The leading principle is that Javascript should do no timezone
manipulation on time data from the past, because that would mean
that the timezone of events recorded in the past depends on things
like the _current_ summer / winter time setting. A graph of the same
data should show the same information regardless of when it is
viewed.

In Lizard we internally work with UTC datetimes as much as possible,
and convert these times to the site's timezone (usually
Europe/Amsterdam) right before handing them to Javascript.

4.16 (2012-12-19)
-----------------

- Fixed urls.py, so it won't recusively include other lizard-* URLs when
running as part of a site.


4.15 (2012-12-20)
-----------------

- Removed animationsettings for now. They're used in a tiny number of older
projects and probably have to be re-instated later on. But the daterange
implementation used by animationsettings has changed anyway. Perhaps
implement it in the projects that need it?

- We're depending on the 2.x version of Django REST framework now. This means
updating other projects that use Django REST framework. For a starting
point, see
http://reinout.vanrees.org/weblog/2012/12/04/django-rest-framework-2.html

- Removed all daterange tests as none of them work. ``daterange.py`` itself
has not been removed as it is used in quite a lot of views.

- Added configchecker test (``bin/django check_config``) whether ``USE_TZ =
True`` is set in your setttings file.

- Added an "add_percentiles" function to FlotGraph, that allows
plotting filled-in "percentile areas" around graphs. Will be
implemented for Matplotlib too, but that's not done yet.

- Added a workaround in ViewStateService, because Forms seem no longer
supported by rest_framework.


4.14 (2012-12-04)
-----------------

- Changed some text and changed location_list to always load initial results
on opening.


4.13 (2012-12-03)
-----------------

- Fixing automatic migration step ``0009`` by deleting/adding the
``identifier`` column on ``CollageEditItem`` instead of altering it. The old
``JSONField``'s implementation is incomplete and wreaks the migration.

- Store current extent when saving a workspace, and load it back again
when loading a workspace which has an extent set.


4.12 (2012-11-27)
-----------------

- Nothing big.


4.11 (2012-11-29)
-----------------

- Slightly refactored the 'workspace_item_toggle' view so that its
main functionality is now in the WorkspaceEdit model, so that it can
be called from other functions as well.
As a result, WorkspaceEdit now has methods 'toggle_workspace_item'
and 'add_workspace_item'.


4.10 (2012-11-22)
-----------------

- Support mixed flot/matplotlib (IE8) graphs.

- Fixed some IE8 issues.

- Added some more zoomLevels for WMS background layers.

- Graphs now reload on a date change.

- Removed some obsolete code regarding animation.

- Changed hover popup to one built with jQuery, as the previously used
OpenLayers one causes an unnecessary redraw on IE8.

- Moved all graph code to lizard-map, which should be a more suitable place
for it.

- Fixed usage of naive datetime objects.

- Added zoom/pan linked graphs.

- Added support for a singleTile WMS background layer.

- Location list now shows some initial results.

- Fixed various small bugs.

4.9 (2012-10-18)
----------------

- Fixed some styling issues.

- Fix test build config, travis & pep8.


4.8 (2012-10-05)
----------------

- Fix a missing css and made some javascript code optional.


4.7 (2012-10-04)
----------------

- Relicensed from GPL to LGPL.

- Added MAP_SHOW_MULTISELECT, MAP_SHOW_DATE_RANGE and MAP_SHOW_DEFAULT_ZOOM
optional settings to make it possible to hide the three default lizard-map
content actions. They're True by default.

- Added popup with subtabs.

- Merged and cleaned various JavaScript files.

- Link to Pillow instead of PIL.

- Move most CSS styling to lizard-ui.

- Fix some styling issues, typo's.

- Revived the collage page.

- Switch to a Twitter Bootstrap based date-range selector.

- Fix legend order.

- Disable obsolete OpenLayers reprojection.

- Changed default graph colours.

- Popup is shown directly after click on map.

- Add some iPad exceptions and add graph navigation.

- Add support for location search.

- Add more resolutions for Rijksdriehoek.

- Started a simple JavaScript view state holder on the client.
In the future this will hold map extent, map layers etc. as well.

- Tables now have borders, as requested.


4.6 (2012-08-23)
----------------

- Fix graphs and popups: switch from jquery-tools tabs to superior jquery-ui tabs.

- Properly resize graphs instead of reloading them.


4.5 (2012-08-14)
----------------

- Fix OpenStreetMap pink tiles at Firefox.


4.4 (2012-08-14)
----------------

- Flot graphs: fallback to .axes label if one is available, because flot only supports a single ylabel.

- Flot graphs: pass x and y limits so we can determine tick size.

- Multiple select: don't show animation when nothing is found.

- Mapnik WMS rendering: reduce memory usage because of buffers being copied multiple times.

- Changed lots of core stuff: no longer combine workspace layers into a single WMS layer.

- Added multi-url legend support.

- Fix some bad hover_popup code.

- OpenLayers: fix iPad.

4.3 (2012-07-10)
----------------

- If a legend_image url is empty, we don't show the legend anymore.


4.2 (2012-07-10)
----------------

- In a map view, you can now provide ``.extra_wms_layers()`` to add extra
WMS to the map. Handy for layers that are really part of a specific content
item. The list of dictionaries that this method has to return is really an
unfriendly API: this needs refactoring later on.

- Internal refactoring. Renamed ``.maps()`` to ``.backgrounds()`` in the
views. This (hopefully) isn't used externally.


4.1.1 (2012-06-29)
------------------

- Importing JSONField in fields.py as otherwise the migrations fail.


4.1 (2012-06-28)
----------------

- Requiring newer django-jsonfield version (which works with django's multi-db
functionality). Removed our custom JSONField in favour of
django-jsonfield's one.


4.0 (2012-06-19)
----------------

- Added flot graph axis label support.

- Some table styling.

- Fix date range popup.

- Readded the option to save a workspace.

- Readded the nothingFoundPopup.

- Support EPSG:3857 alias for google coordinates.

- Added feature to load stored workspace in editable workspace.

- Add moving box on collage-add and multiple select.

- Fix my-collage popups.

- Reinstated multi-select functionality.


4.0b6 (2012-06-01)
------------------

- Add support for bar graphs (Flot).

- Remove an obsolete console.log call.


4.0b5 (2012-05-31)
------------------

- Removed OpenLayers.ImgPath of theme 'Dark'.

- Minor styling fix for workspaces.

- Add the new FlotGraph.

4.0b4 (2012-05-29)
------------------

- Fixed Javascript not finding href attributes during click events.


4.0b3 (2012-05-29)
------------------

- Collage and workspace are now styled using tables.


4.0b1 (2012-05-29)
------------------

- Added missing dependency lizard_security.

- Fixed popup and popup contents styling.

- Collage and workspace UI working again.


4.0a1 (2012-05-18)
------------------

- Requiring lizard-ui 4.0 alpha: the new twitter bootstrap layout.

- Using compiled css instead of less.

- Removed old HomepageView and renamed the MapIconView.

- Using new twitter-bootstrap layout. Using the MapView class based view is
now really mandatory to get everything to work.

- Renamed /media to /static. That's django-staticfile's new standard.

- Timeseries can now be localized in Graph object.

- Fixed syntax error in jquery.workspace.js.

- Adds STATIC_URL to application icons.

- Making the normal AppView the main cbv instead of the temporary MapView name.


3.31 (2012-05-15)
-----------------

- Changed map click popup to jQuery ui dialog: it is now movable and
resizable.

- The maximum number of tabs in popups has been made configurable.

- If an item is removed from the workspace while rendering (for instance because an Exception
was raised), the page loads without giving an internal server error caused by trying to
create a Legend.


3.30 (2012-04-26)
-----------------

- Added one icon.


3.29 (2012-04-25)
-----------------

- Added two icons.


3.28 (2012-04-13)
-----------------

- Re-enabling hover functionality on saved workspaces.


3.27.1 (2012-04-13)
-------------------

- Also removed references to touch.js and lizard_touch.js from the templates...


3.27 (2012-04-13)
-----------------

- Required lizard-ui 3.14 (new Openlayers).

- Removed touch.js, necessary with the new Openlayers version.

- Uncommented extent() in WorkspaceItemAdapter. It should be there
because it is one of the methods that can be overridden by
implementing adapters.

3.26 (2012-04-06)
-----------------

- Changed collage detail template so that apps can configure it a bit more.
Collage items (that are put in groups on the collage page) have properties
that control the header shown over the group (data_description), which edit
dialog to show for a collage item edit button (collage_detail_edit_action),
whether to show the whole Edit block at all (collage_detail_show_edit_block),
and whether to show the statistics block (collage_detail_show_statistics_block).

These functions in turn call functions in their adapters, with an identifier
as argument (because one adapter can have items in different groups, with different
settings. This way it gets the identifier of the first item in each group):

def collage_detail_data_description(self, identifier, *args, **kwargs):
default 'Grafiek'
def collage_detail_edit_action(self, identifier, *args, **kwargs):
default 'graph'
def collage_detail_show_edit_block(self, identifier, *args, **kwargs):
default True
def collage_detail_show_statistics_block(self, identifier, *args, **kwargs):
default True

*args and **kwargs are meaningless but present in case the functions' signatures
change in the future. These functions can be overridden in your adapter.


3.25 (2012-04-04)
-----------------

- Improved docstrings at a few places (mainly location() in
WorkspaceItemAdapter)

- Added method 'adapter_layer_json' to WorkspaceItemAdapter, helpful
to generate this bit of json when it's needed.

- Added 'adapter': self to html_default's template context variables.
This gives templates access to adapter's methods and attributes,
like adapter.adapter_class and adapter.adapter_layer_json.

3.24 (2012-03-05)
-----------------

- It's now possible to not use a popup_click_handler.


3.23 (2012-02-16)
-----------------

- Added grouping_hint option to the result of adapter.search(), to make it
possible for a single workspace layer to open a popup with multiple tabs.


3.22 (2012-01-27)
-----------------

- Translation fixes, added breadcrumb to the workspace storage
page. Last fixes before "Lizard 3.0" release?


3.21 (2012-01-26)
-----------------

- Make sure graphs never zoom in so far that they show Y-axis values
with more than 2 decimals.


3.20 (2012-01-26)
-----------------

- Changed waterstand icon from triangle pointing up to triangle
pointing down.

- Changed workspace save/load functionality. Now workspaces can only
be saved, which gives them a "secret slug" (a string with random
characters), and the workspace detail page is opened in a new page.
The URL to this page includes the secret slug and can be shared with
others. The workspace shown on the page can't be changed. The
"workspace load" button is gone until we have a nice user interface
that can show many saved workspaces, and a way to deal with user
privileges.

This is minimal functionality that will be improved in later
versions.

3.19 (2012-01-23)
-----------------

- Removed Download button because we don't have working background maps

- Added a nice calendar to the period selection dialog

- Fixed bug with opacity slider and WMS layers

- Added some functions for the collage detail page, so that different apps
can show different titles and/or hide the Edit button.

3.18 (2012-01-17)
-----------------

- Breadcrumbs for application screens, first
page of applications

- Possibility for apps to add their own breadcrumbs


3.17 (2012-01-13)
-----------------

- Fixed bug where items on the collage page didn't have access to the
request (and therefore not to start- and end dates).


3.16 (2012-01-10)
-----------------

- Fix bug with editing collages.


3.15 (2012-01-05)
-----------------

- Fix bug where X-label of graph wasn't visible.


3.14.1 (2012-01-05)
-------------------

- Nothing changed yet.


3.14 (2012-01-05)
-----------------

- Hack to prevent error when a dictionary key doesn't exist.


3.13 (2012-01-04)
-----------------

- Skip map layers without params in downloaded image. (internal server
error fix)

if a given item's name is present in the workspace.

3.9 (2011-12-21)
----------------

- Removed some max_lengths in forms.py, because it caused valid forms
to fail. There is no reason JSON fields should have a hard limit,
and other fields should have the same limit as in the model.

3.8 (2011-12-20)
----------------

- Added 'transform_point' utility function that can use the site's
projection Setting to transform points to a desired projection.


3.7 (2011-12-20)
----------------

- Made it possible to scale y-axis of graphs manually (it used to be
possible, except then the y-axis would be recalculated afterwards)


3.6 (2011-12-19)
----------------

- WorkspaceItemAdapter's html_default() can use the
extra_render_kwargs kwarg again. Subclasses can use it to send
variables to the template and still use the html_default method for
most of the work.

- Added a block popup_title to html_default.html so that the title
can be changed in extending templates.


3.5.2 (2011-11-29)
------------------

- Removed object-actions block with the non-existing 'help-workspace' url that
broke the interface.


3.5.1 (2011-11-28)

- Moved export csv button to table "Bewerken".

- Statistics in collage screen are now below edit options.

- Changed geoserver url to ip address, see #3283.

- And yet another (last) bug in **identifier in
html_default. Apparently keys from identifiers are transformed to
unicode on the server, while the development environment works just fine.


3.1.3 (2011-10-03)
------------------

- Convert keys of adapter.identifier to str before using it in
html_default.


3.1.2 (2011-10-03)

- Pylint.

- Added option "add to selection" in map popup.

- Removed console.log and alert from js.

- Fixed popup dialog size, it will now always be the default size.

- Fixed "pan & zoom to default location". After changes in workspace

3.0 (2011-09-28)
----------------

Lizard 3: Make sure you read the readme before upgrading to this version.

- Rebuilt collage screen with grouping.

- Added migration for new models; South introspection rules.

- Integrated search_name in search_coordinates.

- Various functions work on WorkspaceEdits and WorkspaceStorages.

- Added generic dialog javascript code.

- Added generic POST action javascript code.

- Made app_screen class-based, with helper class WorkspaceView.

- Added new workspaces, collages.

- Added PeriodMixin with tests.

GoogleTrackingMixin, WorkspaceMixin, WorkspaceEditMixin, MapMixin,
CollageMixin, DateRangeMixin.

- Added class based views: AppView,
WorkspaceStorageView, HomepageView, CollageDetailView.

WorkspaceLoadView, DateRangeView, CollageItemEditorView,
WorkspaceStorageListView, CollageView, CollageEmptyView,
CollageItemEditView, CollagePopupView, WorkspaceEmptyView.

- Adapter stuff: AdapterMixin, ImageMixin, AdapterImageView, AdapterCsvView.


2.5 (2011-09-23)
----------------

- Not mentioning pyproj as a dependency anymore, even though we *do* need
it. Somehow the osc.recipe.sysegg buildout recipe doesn't really want to
play nice with it.

- When there's an non-existing adapter (=invalid/non-existing entry point
name), we now also delete the workspace item instead of raising an
error. There just might be an old workspace item laying around in a
customer's session and we shouldn't keep the customer stuck in an
error 500.


2.4 (2011-09-22)
----------------

- The context processor now first weeds out faulty workspace items before
attempting anything else. This prevents an "error 500": normally the
workspace item gets deleted, but the .is_animatable call still breaks on the
just-deleted workspaceitem. Now we first remove the faulty ones beforehand.


2.3 (2011-09-20)
----------------

- Made the automatic invalid-workspaceitem-deletion more robust.

- Removed the youtube popup. Unused at the moment. And the implementation was
terribly hardcoded.

- Commented out all the debugging in the symbolmanager


2.2 (2011-09-02)
----------------

- 2.1.13 stated "please clear your session info when you upgrade to this
version as the fix to #3181 stores different information." This release
fixes that. No session data deletion is needed anymore.


2.1.13 (2011-09-01)
-------------------

- Fixed a problem in the date range selector, namely that the day of the end
date with move to the next day when the user selected another month of the
end date (#3181).

- Added request to templatetag snippet_group to be able to use request in
adapters' html function.


2.1.12 (2011-08-30)
-------------------

- Added try/except around hotshot in profile middleware, because it
requires python-profiler.

- Added request to layout_options in popup_collage_json. The request
is needed in some adapter.html functions in order to get user
datetime/periods.


2.1.11 (2011-08-30)
-------------------

- Fixed progress cursor in popup_click_handler().

- Zoom to closest extent is no longer used for workspace items.


2.1.10 (2011-08-24)
-------------------

- Requiring lizard-ui 3.0 now, which also means Django 1.3. Updated the
buildout and the testsettings for that. We're also using the KGS (known good
set) now to limit the amount of version pinning.


2.1.9 (2011-08-16)
------------------

- Edited mouse progress on click in map.


2.1.8 (2011-08-05)

- Changed breadcrumbs according to #2499. The behaviour is as follows:
home for home screen and home -> screen for other screens.

- Fixed clicking bug in FF5: set pixelTolerance to null instead if 0
is a workaround for the OpenLayers bug. #3108.


2.1.6 (2011-07-29)
------------------

- Added function to convert WGS84 coordinates to RD.

- Updated point_3.png: the upper left corner contained an error.

- Added truncation of workspace-item-names to 80 characters (the
server would otherwise crash on longer names).

- Now using QuerySet.count instead of len(QuerySet.all()) in workspace
manager.

- Added some rel=tipsy html parameters.

- Pinned lizard_ui to 2.1.4


2.1.5 (2011-07-25)
------------------

- Settings are now cached. After deleting and saving the cache will be
invalidated.

- Added setting option javascript_hover_handler. Setting this option
to 'popup_hover_handler' will enable mouse overs. Note: run a
migrate after upgrading, the Setting.key field can now be 40
characters.

- #3096: fixed blue info button in workspace-acceptables (they appear
in lizard-shape).


2.1.4 (2011-07-14)
------------------

- iPad update: the (+) works again as well as some trees on the
sidebar. #3003, #3004.


2.1.3 (2011-07-12)
------------------

- Removed draggability of workspace-acceptables.

WorkspaceItem.has_extent we now just detect if the function is at
all present. #3041, #3036.

- Added wms layers to transparency function. #3039.

- Updated googlemaps_api_keys in fixture: the new key is for
lizardsystem.nl and all its subdomains.

- Updated workspace_item_empty: When emptying workspace, the
snippet-groups will also be deleted. #3031.

- Added try/except around search_coordinates and search_name for
#3033.


2.1.2 (2011-06-30)
------------------

- Adapter.legend: removed "force_legend_below" behaviour when width <
500. TODO: fix force_legend_below or remove.

- Changed adapter.legend: self.axes.legend instead of
self.figure.legend. Everything seems ok.


2.1.1 (2011-06-30)
------------------

- Added google_tracking_code from settings to context_processor, if
available.

- Added try/except in WorkspaceCollageSnippetGroup.values_table (used
in "show tables" of collage view), because some adapters don't
implement the adapter.values function.


2.1 (2011-06-29)
----------------

- Temporary disable sorting in workspace when a new workspace-item is
being added. Solves #2961.

1.87 (2011-06-17)
-----------------

- Re-enabled custom y tick locator amount selection.

- Showing the table now looks at the table belonging to the button by means of
a wrapper div, which is more reliable.

- Fixed the problem that a hidden popup would remain populated and re-evaluated
(ticket 2892).


1.86 (2011-06-16)
-----------------

- Added bare try/except around wms workspace layer looping to prevent
the function to crash.

- Added transparency_slider to context variables. From now on the
transparency_slider is enabled by default.

- Added optional popup_video_url parameter to the ``homepage()`` view. This
video url, when used, should point to the embed urls of YouTube videos.
Currently the sizes are hardcoded, so this is work-in-progress.
The video is shown once per day, max.

- Modified graph: less yticks, bigger ylabel, dutch monthnames,
yearlabel is now at first tick of year.


1.85 (2011-06-10)
-----------------

- Fixed tab setup in graph popup: no more unneeded reloading of the html. Also
the graphs aren't reloaded more often than necessary.

the plus sign, deleting a workspace item or deleting a collage item.


1.81 (2011-06-03)
-----------------

- Workspace items and snippets take up a fixed one-line height now. The
overflow is hidden. This makes the interface more predictable.


1.80 (2011-06-01)
-----------------

- Added default "javascript_click_handler" (namely ``popup_click_handler``) to
the context via the lizard_map context processor.

- By default, a hover_click_handler isn't added anymore unless you specify one
yourself in the context. Most sites don't need/want it.

- Fixed overly-aggressive reloading of map layers. This improves the performance.

- Added checkboxes and functionality to collage-items (snippets).


1.79 (2011-05-30)

- Changed "zoom to box" instead of "pan to center" when clicking
workspace-acceptable or workspace-item magnifying glass.

-----------------

- Added support for ApplicationScreens.

-----------------

1.8 (2010-08-30)
----------------

- Bugfix for when no statistics are available.


1.7 (2010-08-27)
----------------

- Graph and collage popups now use the "regular" jquerytools popup instead of
the OpenLayers in-the-map popup. Visually cleaner, clearer and prettier.
And easier to maintain and to get right.

- Various visual fixes.

- Deleting a workspace item also deletes the corresponding snippets.

- Added color pulldown for collage view settings (instead of requiring you to
know the internal matplotlib color code names :-) )


1.6 (2010-08-26)
----------------

- Animation slider and name-hover are now also working in the default
workspace view.

- Name hover is now placed just to the lower right of the cursor. This way
you can still click on the item you hovered above instead of your click
being blocked sometimes by the hovering name.

- Added slightly more whitespace to the right of legend-less graphs: this
prevents (most) labels from being cut off.


1.5 (2010-08-26)
----------------

- Layout improvements for popups and tables.

- Added dateperiods: calculate periods for use in graphs.

- Added styling for popups.


1.4 (2010-08-23)
----------------

- WorkspaceCollageSnippetGroup's name was a TextField (=multiline) instead of
a simple CharField. Oracle stores a TextField as a "NCLOB" and has some
restrictions on them (no index, no .distinct()). Anyway, this blew up on
an oracle-using installation. Fixed now.

- Removed double value_aggregate() method from base adapter: the extra one
raised a NotImplemented error and overshadowed the real method.


1.3 (2010-08-18)
----------------

- Requiring our dependencies that must be installed with system eggs. We use
the osc.recipe.sysegg in our own buildout to grab them from the system. A
sample config is included in the readme.

- Added optional legends.

- Add option to show tables in collage view.

- Importing the simplejson module in a different way to please windows in
combination with python 2.6.


1.2 (2010-08-16)
----------------

- Added a bit of test setup to make xml test reports possible (for integration
with Hudson). Similarly for coverage reports, also for Hudson. Automatic
code quality monitoring!

- Implemented snippet groups. Snippet groups group similar snippets in
a collage.

- Removed site-specific breadcrumbs.

- Refactored collage view. One can now edit graphs in the collage
view. The graph-only editor has been removed.

- Added an animation slider for showing map layers at specific points in
time. Only shown when there are workspace items that support it.

- Removed graph-properties that were stored in the session.

- Passing extra 'request' keyword argument to all adapter layer() methods.
**Warning**: This needs refactoring in all adapters. Advance warning:
we'll probably refactor the adapters to get the request in their
``__init__()`` method later on.


1.1 (2010-07-16)

class for image replacement.

-----------------

- Better empty height/width handling for images.

- Slightly bigger search radius when clicking on a map.

0.9 (2010-06-18)
----------------
