Fields with repeatable data grid (table-like) for z3.cform

Project description


Provides a field with a datagrid (table), where each row is a sub form.

It is a z3c.form implementation of the Products.DataGridField .

This product was developed for use with Plone and Dexterity.


Add collective.z3cform.datagridfield to your buildout eggs:

eggs =

Example usage

This piece of code demonstrates a schema which has a table within it. The layout of the table is defined by a second schema:

from collective.z3cform.datagridfield.datagridfield import DataGridFieldFactory
from collective.z3cform.datagridfield.row import DictRow
from plone.autoform.directives import widget
from plone.autoform.form import AutoExtensibleForm
from z3c.form import form
from zope import interface
from zope import schema

class ITableRowSchema(interface.Interface):
    one = schema.TextLine(title=u"One")
    two = schema.TextLine(title=u"Two")
    three = schema.TextLine(title=u"Three")

class IFormSchema(interface.Interface):
    four = schema.TextLine(title=u"Four")
    table = schema.List(


class EditForm(AutoExtensibleForm, form.EditForm):
    label=u"Demo Usage of DataGridField"
    schema = IFormSchema

And configured via zcml:


Also it can be used from a supermodel XML:

<field name="table" type="zope.schema.List">
  <value_type type="collective.z3cform.datagridfield.DictRow">
  <form:widget type="collective.z3cform.datagridfield.DataGridFieldFactory"/>


The data can be stored as either a list of dicts or a list of objects. If the data is a list of dicts, the value_type is DictRow. Otherwise, the value_type is ‘schema.Object’.

If you are providing an Object content type (as opposed to dicts) you must provide your own conversion class. The default conversion class returns a list of dicts, not of your object class. See the demos.


Row editor handles

Widget parameters can be passed via widget hints. Extended schema example from above:

class IFormSchema(interface.Interface):
    four = schema.TextLine(title=u"Four")
    table = schema.List(

        display_table_css_class="table table-striped",
        input_table_css_class="table table-sm",

Manipulating the Sub-form

The DictRow schema can also be extended via widget hints. Extended schema examples from above:

from z3c.form.browser.checkbox import CheckBoxFieldWidget

class ITableRowSchema(interface.Interface):

    two = schema.TextLine(title=u"Level 2")

    address_type = schema.Choice(
        title="Address Type",
        values=["Work", "Home"],
    # show checkboxes instead of selectbox

class IFormSchema(interface.Interface):

    table = schema.List(
        title=u"Nested selection tree test",

Working with

To use the field with, you’ll have to use a version of the field that has PersistentField as it’s base class:

from collective.z3cform.datagridfield.registry import DictRow

JavaScript events

collective.z3cform.datagridfield fires jQuery events, so that you can hook them in your own Javascript for DataGridField behavior customization.

The following events are currently fired against table.datagridwidget-table-view

  • beforeaddrow [datagridfield, newRow]

  • afteraddrow [datagridfield, newRow]

  • beforeaddrowauto [datagridfield, newRow]

  • afteraddrowauto [datagridfield, newRow]

  • aftermoverow [datagridfield]

  • afterdatagridfieldinit - All DGFs on the page have been initialized

Example usage:

var handleDGFInsert = function(event, dgf, row) {
    row = $(row);
    console.log("Got new row:");

// Bind all DGF handlers on the page
$(document).on('beforeaddrow beforeaddrowauto', '.datagridwidget-table-view', handleDGFInsert);


More examples are in the demo subfolder of this package.

  • Row UI buttons optimizations Change row UI elements from anchor to buttons for better semantics. Fix Boostrap classes, remove unused attributes, add a title to buttons. [thet]

  • Change UI element classes

    Remove non-unique id attributes from UI buttons and add classes instead. Let the button functionality be initialized by the pattern.

    Breaking change:

    In this version a pattern handles all the JavaScript functionality to ensure best possible encapsulation between different instances of the datagridfield widget. If you have customized templates, make sure you do the following:

    • Add the class pat-datagridfield to the datagridwidget-table-view nodes (,

    • Add the following classes instead of ids to the ui buttons as shown in this map (,

      • #btn-addrow -> .dgf–row-add

      • #btn-deleterow -> .dgf–row-delete

      • #btn-moveup -> .dgf–row-moveup

      • #btn-movedown -> .dgf–row-movedown

  • Clone events when adding new row - fixes bug where browse button of plone.formwidget.contenttree did nothing for new rows [anthonygerrard]

  • Reindex more indexed attributes of cloned row [anthonygerrard]

0.8 (2011-09-24)

  • Avoid using the “row” CSS class. [davisagli]

  • Fixes to work with jQuery 1.3.x (use .remove() instead of .detach(), fetch data attributes a different way, and avoid live binding the change event). [davisagli]

  • Don’t error out when getting a FormatterValidationError, pass it on to z3c.form instead. [claytron]

  • Give manipulator images a relative src rather than absolute. This previously meant the widget didn’t work on sites without Plone/Zope at the root of the domain. [davidjb]

  • During auto-insert, add our new row into the document first, before reindexing it and changing its elements’ IDs. This allows Javascript that depends on these IDs (such as plone.formwidget.autocomplete) to pick up the correct fields. [davidjb]

  • Tidying up and reducing complexity of auto-insert functionality [davidjb]

  • Removing unnecessary auto-insert bind and unbind as this is already covered by jQuery’s live() function against the auto-append class. Adding/removing this class against rows automatically does this. [davidjb]

  • Resolved issue with auto-insert functionality not working by removing table-specific check in Javascript. [davidjb]

0.7 (2011-07-01)

  • Changed markup/javascript to prevent duplicate HTML id attributes. Changed Javascript to allow for datagrid page templates that don’t use tables. [dextermilo]

  • Improve spacing in CSS. [davisagli]

  • Revert my fix to ensure that blank rows are added, because it duplicated a fix in z3c.form resulting in extra rows. [davisagli]

0.6 (2011-05-17)

  • Search for datagridInitialise and datagridUpdateWidgets on the parent form, also when in a fieldset. [maurits]

  • Register templates on to take precedence over that packages list widget templates. [elro]

  • Make sure that updateWidgets is called to add blank rows even if the widget has no value. [davisagli]

  • When extracting a row value fails due to a validation error, convert widget values to field values so the value can be successfully applied to the grid widget. [davisagli]

  • Register a plone.supermodel handler for the DictRow so it can be used in supermodel models. [davisagli]

  • Depend on collective.z3cform.datagridfield_demo as a test extra; use the browser view from this package in the tests. [maurits]

  • _validate still used when import/exporting, fix up code so it works [lentinj]

  • Add a DictRow serializer for transmogrify.dexterity [lentinj]

  • Only use width:100% on input cells that are the only element in the cell [lentinj]

  • Reorder row indices backwards when adding rows. This means that adjacent rows don’t share the same index temporarily, for example:- - Row 1 and 2 contain input:radio based widgets - Row 0 added, row renumbering starts - Row 1 widgets renamed 2 - Both sets of input:radio share the same name, one deselected - Row 2 widgets renamed 3 - … [lentinj]

  • Use jQuery to clone rows, and clone the jQuery events on the rows. [lentinj]

  • Implemented reorder functionality

  • Removed unnessary dependency on dexterity (tks Laurence Rowe).

  • Removed unnessary dependency on grok (tks Laurence Rowe).

0.4 (2011-02-06)

  • Renamed the demo pages. The starting point is now @@demo-collective.z3cform.datagrid .

  • The widget can now be configured via the updateWidgets method. It is no longer necessary to create a custom factory.

  • The columns can now be omitted.

  • Provide a set of demo views for Object access.

0.3 (2011-02-04)

  • The auto-append functionality did not bind correctly for popup forms. I switched to using instead of binding at document load time.

  • Added a menu to the demo pages

  • Added a display only form option.

  • Fixed the restructured text of the main README.txt so that it will show more friendly in PyPI.
