Products.DataGridField 1.8.1

A table input component for Plone.

Latest Version: 1.9.0

DataGridField

Released under the GNU General Public License

A table input component for Plone. Uses Javascript to make entering tabular data more user friendly process - there are no round trip HTTP requests to the server when inserting or deleting rows.

Features

o Any number of columns set by a developer

o Any number of rows filled by a user

o Insert and deleting rows without submitting a form

o Many different column types

Requirements

o Plone 4 (for Plone 3, use the latest release in the 1.7 branch or 1.6 branch, for Plone 2.5, use the latest release in the 1.6 branch)

o A browser with Javascript support. There isn't yet graceful degradation for
browsers without Javascript.

Installation

This version of DataGridField is distributed as an egg at the Python Package index. Information about configuring either for a zope instance house a Plone site can be found by reading the Installing an Add-on Product tutorial and the "Installing a third party product" section of the Managing Project with zc.buildout tutorial.

Once you've succesfully done this, you can use the Add/Remove Products screen to install the DataGridField into your site. See below for information about experimenting with the demo types.

Quality

o Tested with Firefox 2.0, IE 6, IE 7

Usage examples

Simple example with three free text columns:

schema = BaseSchema + Schema((

DataGridField('DemoField',
        widget = DataGridWidget(),
        columns=('column1','column2','The third')
        ),
))

Complex example with different column types and user friendly labels:

# Plone imports
from Products.Archetypes.public import DisplayList
from Products.Archetypes.public import *

# Local imports
from Products.DataGridField import DataGridField, DataGridWidget
from Products.DataGridField.Column import Column
from Products.DataGridField.SelectColumn import SelectColumn

class DataGridDemoType(BaseContent):
    """A simple archetype

    """

    schema = BaseSchema + Schema((
        DataGridField('DemoField',
                searchable = True,
                columns=("column1", "column2", "select_sample"),
                widget = DataGridWidget(
                    columns={
                        'column1' : Column("Toholampi city rox"),
                        'column2' : Column("My friendly name"),
                        'select_sample' : SelectColumn("Friendly name", vocabulary="getSampleVocabulary")
                    },
                 ),
         ),

        ))

    def getSampleVocabulary(self):
        """
        """
        """ Get list of possible taggable features from ATVocabularyManager """
        return DisplayList(

            (("sample", "Sample value 1",),
            ("sample2", "Sample value 2",),))

For more examples, see unit test code.

Notes

o Since DataGridField 1.5, if you wish to retain old way of automatic row inserting.

Here is a bit logic behind all this - otherwise there will be an extra row added when you edit DGF and press save.

o You must set property auto_insert = True to DataGridWidget

o You must set property allow_empty_rows = False to DataGridField

Known bugs

o Sometimes on Firefox column sizes start changing after the user enters some
data. Not sure if this is a Firefox bug, though.

o Prefilled default values work only for text and select columns

o Radio button and link column postback is not handled properly. This needs
fixes very deep into Zope (ZPublisher). If the form validation fails, link column and radio button columns lost their values.

Demo

A demo type is included. It is disabled by default. This type is neither pretty nor very functional, but demonstrates how a data grid should be used. You can install this type into your site by running the "DataGridField (Example DGF content types)" from the Generic Setup tool within the ZMI.

1.8a1 (2009-11-07)

  • Fixed possible TypeError when submitting the base_metadata form. [maurits]
  • In the view macro use the supplied accessor instead of thinking we know how to get the accessor ourselves as that gives wrong results with LinguaPlone. Fixes http://plone.org/products/datagridfield/issues/14 [maurits]

  • Adaptation to work on Plone 4/Zope 2.12. For Plone 3, please use the 1.7 or 1.6 branches. [vincentfretin]

1.7 (unreleased)

  • When there is an empty row with the template_row_marker and validation fails (for any field), make sure we do not end up with two empty rows. [maurits+vpretre]
  • added LinesColumn (used as custom vocabulary source in PFGDataGrid field) [naro]
  • added unique column classnames for thead and tbody table section to identify columns and modify it's properties through css (specially width for each column seperatly). Now we can remove the style attributes and do some template code cleanup. [saily]

  • Move installation back to GenericSetup, end of Plone 2.5.x support [andrewb, but real thanks goes to wichert]

1.6 (2009-01-28)

  • Merging of colliding datagridwidget.css and datagridwidget.css.dtml files. Fixes issue #30: http://plone.org/products/datagridfield/issues/30. Which file was ultimately selected appears to be inconsistent. If you're depending upon an overridden version of either and notice bugs with regards to hidden columns and/or rows appearing or the promise of adding additional DGF rows when using the FixedColumn, you'd be well suited to reconcile your customizations with the merged files from r10445 at: http://dev.plone.org/archetypes/changeset/10445 [andrewb]

1.6rc1

  • Adding Plone 2.5.x DataGridField profile "default_25x" to overcome difference in GS namespace for the registration of our skin directory. Without this, one needed to manually add the correct FSDV within the portal_skins tool for .pt, .dtml, images, etc. to exist with the DataGridWidget's skins directory. [andrewb]

  • Adding back Extensions and Install.py with install() function for consistent Add/Remove Products experience back to Plone 2.5.x, which did not handle GenericSetup profile-based installation. The install code delegates to Generic Setup for maximal code reuse. The justification is that to completely remove a Add/Remove Product support in Plone 2.5.x between a beta 2 and beta 3 release is overly extreme. This will workaround will be rectified in a future release. [andrewb]

    Note: This was added manually without history because the the eggified version of DataGridField was moved, rather than copied, thus no history at: http://dev.plone.org/archetypes/log/Products.DataGridField?action=follow_copy&rev=&stop_rev=&mode=follow_copy

  • Updated installation instructions, info about example types, and added note about ceasing Plone 2.5.x support [andrewb]

  • Removed check of "@@plone_lock_info" within example types' GS declarations, so actions render in pre-Plone locking era [andrewb]

  • Made all tests pass in Plone 2.5.x, 3.0.x, and 3.1.x [andrewb]

  • Made explicit names for the different GS profiles that one might choose to install within portal_setup [andrewb]

1.6 beta 3

  • Eggified in Products.AddRemoveWidget [SteveM]
  • Register skin layer correctly. [maurits]
  • Move installation to GenericSetup. [wichert]
  • Removed lots and lots of unneeded import. Pyflakes found that Plone 2.1 support has been broken for a while, so stop claiming it's still supported. [wichert]
  • Added validator isDataGridFilled (copied from Poi, where it can later be removed). Use this as validator on a DataGridField if you want it to have at least one entry: currently a bogus/hidden entry always remains even when you remove all real entries, so making a DataGridField required has no real effect. See http://plone.org/products/poi/issues/139 and 160. [maurits]

1.6 beta 2

  • Disabled INSTALL_DEMO_TYPES from config.py. [andrewburkhalter]

1.5

  • Pop-up help column by Juan Grigera
  • Added CheckboxColumn by Radim Novotny
  • Plone 3.0 compatible (fixed CMFCorePermissions import)
  • Fixed http://plone.org/products/datagridfield/issues/16 (applied the patch)
  • DataGridField has new property allow_oddeven. Setting this to True will highlight odd end even rows in the view/edit tables. Default: False
  • FixedColumn has optional parameter "visible" (default True). Setting this to False will hide (using css) column from both - view and edit forms.

1.5rc3

  • Added CheckboxColumn. Implementation based on RadioColumn, so there are same bugs. CheckboxColumn lose values if any field on the form raises validation error. Be aware of that, better does not use CheckboxColumn in forms with required fields or fields with validators. [Contributor: naro, radim novotny]

1.5rc2

  • Fixed row adding in IE. This was one of the most horrible debugging session I have had. There was some obscure IE bug which prevented making a DOM node orignally hidden to visible. I created "hacky" workaround for this. Tested in IE 6.0 and FF 1.5.
  • Wolfram Fenske's I18N patch is disabled, since it doesn't work in Plone 2.5. The code is almost there. If someone wants to make it complete, it shouldn't take too much time.

1.5rc1

  • Added workaround for bad DGF initializing which caused empty rows when DGF was created programmatically

1.0 to 1.5

  • Plone 2.5 compatibility guaranteed

  • DGF row manipulators rewritten. Automatically adding new rows feature is now optional, thus making it possible for columns to have prefilled default values without creating a mess. Disabling auto insert is necessary for columns like SelectWidget which don't have empty default values.

  • Refactored page template code to be more easily extendable. Now CSS file is used for styling DataGridWidgets.

  • New column type: Link column

  • (Wolfram Fenske) I18N patch

    Archetypes widgets have an attribute i18n_domain, which is used to determine which message catalog to use for translation. In DataGridField, this attribute is ignored.

    I have attached a small patch (in fact, smaller than this bug report) which fixes these problems. I didn't want to introduce a lot of new code, so I did the translation of the labels in the Column class, not in the page template, which might also have been a good way to do it. Since the functions "getLabel()" and "getColumnLabels()" are only called by the page template anyway, I believe this is not an issue. But if you'd rather translate the labels in the page template, please let me know and I'll write a different patch.

  • (Juan Grigera) Marshaller patch

    I enjoyed your DataGriedField/Widget product for Plone, and would like to contributea small patch/bugfix. In the field mutator (set) the passed value is not always a record, but sometimes a string. In fact the RFC822Marshaller passes a string.
