djangosenchatools 1.0.5

Django management command to simplify building extjs and sencha touch apps with Sencha tools.

#################

#################

Django management commands for the JSBuilder commands in `Sencha SDK Tools`_.
Unfortunately, the JSBuilder commands provided by Sencha Tools needs some
workarounds to work when the HTML document and resources are not in the same
directory. We have turned these workarounds into a Django management command
available in the *djangosenchatools* app.

Install
=======

Install the python package::

$ pip install djangosenchatools


Add it to your django project::

INSTALLED_APPS = [
...
'djangosenchatools'
]


Usage
=====

First, we need a Django ExtJS4 application. See `django_extjs4_examples`_ for
an example application. We use the ``minimal_extjs4_app`` as our example.

.. note:: The ``senchatoolsbuild`` management command runs ``collectstatic``.

.. note:: You need to run the Django server (``manage.py runserver``) for all commands except --listall.


Build one app
-------------

Run::

$ python manage.py senchatoolsbuild --url http://localhost:8000/minimal_extjs4_app/ --outdir /path/to/outdir

With ``--url`` and ``--outdir``, the senchatoolsbuild command runs ``sencha
create jsb`` and ``sencha build``, and puts the result in the ``--outdir``.
Run with ``-v3`` for full debug output if you want to see what the command does.


Build all INSTALLED_APPS
------------------------

``senchatoolsbuild`` can autodetect sencha apps and build them all in their
respective static directories. Run with ``--help`` and see the help for
``--buildall`` to see how apps are detected.

To list detected apps, their ``--outdir`` and ``--url``, run::

$ python manage.py senchatoolsbuild --listall

Add ``-v3`` to see skipped apps, and why they are skipped.

To build all detected apps, run::

$ python manage.py senchatoolsbuild --buildall


Build one app by name
---------------------

You can build a single app in ``INSTALLED_APPS`` using the same method of
detecting outdir and url as ``--buildall`` using ``--app``::

$ python manage.py senchatoolsbuild --app minimal_extjs4_app


Using --watch
-------------

Use ``--watch`` to automatically rebuild on file changes:

$ python manage.py senchatoolsbuild --app minimal_extjs4_app --watch /path/to/directory/containing/minimal_extjs4_app

Use ``-v2`` for debug out. By default, only ``*.js``-files trigger rebuild
events, however you can change this using these settings (shown with their defaults):

#: Files to include
DJANGOSENCHATOOLS_WATCH_INCLUDE = ['*.js']

#: Files to exclude
#: - Matched after INCLUDE, so you can include a general pattern, and
#: exclude specific files or dirs.
DJANGOSENCHATOOLS_WATCH_EXCLUDE = ['*.*.swp', '*~', '*.pyc', '*.pyo',
'*app-all.js', '*all-classes.js']

_Note_: All patterns match against the absolute path of the file.


Integration with django_extjs4
==============================

This app is made to work with `django_extjs4`_, however they are losely
coupled. The only place where you are likely to notice that they work together
is that ``senchatoolsbuild`` checks that ``settings.EXTJS4_DEBUG==True``. You
can disable this check using ``--no-check-settings``.


Building apps that require authentication
=========================================

Add the following to your ``settings.py``::

MIDDLEWARE_CLASSES += ['djangosenchatools.auth.SettingUserMiddleware']
AUTHENTICATION_BACKENDS = ('djangosenchatools.auth.SettingUserBackend',)
SENCHATOOLS_USER = 'myuser'

Where ``SENCHATOOLS_USER`` is the user that you want to be authenticated as
(the user must exist). **NEVER** use this backend/middleware in production.


Reccommended setup
------------------

We reccommend that you create a separate settings.py for ``senchatoolsbuild``
where you set the required settings. Here is our ``djangosenchatools_settings.py``::

from settings import *
EXTJS4_DEBUG = True
MIDDLEWARE_CLASSES += ['djangosenchatools.auth.SettingUserMiddleware']
AUTHENTICATION_BACKENDS = ('djangosenchatools.auth.SettingUserBackend',)
SENCHATOOLS_USER = 'grandma'

We use this settings module whenever we build apps using ``senchatoolsbuild``::

$ python manage.py senchatoolsbuild --buildall --settings djangosenchatools_settings
