Introduction
============

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.

:target: https://github.com/collective/collective.z3cform.datagridfield/actions/workflows/test.yml

Installation
============

Add collective.z3cform.datagridfield to your buildout eggs:

.. code-block:: ini

[buildout]
...
eggs =
collective.z3cform.datagridfield

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:

.. code-block:: python

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(
title=u"Table",
value_type=DictRow(
title=u"tablerow",
schema=ITableRowSchema,
),
)

widget(table=DataGridFieldFactory)

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

And configured via zcml:

.. code-block:: xml

Also it can be used from a supermodel XML:

.. code-block:: xml



Table

your.package.interfaces.ITableRowSchema


Storage
-------

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.

Configuration
=============

Row editor handles
------------------

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

.. code-block:: python

class IFormSchema(interface.Interface):
four = schema.TextLine(title=u"Four")
table = schema.List(
title=u"Table",
value_type=DictRow(
title=u"tablerow",
schema=ITableRowSchema,
),
)

widget(
"table",
DataGridFieldFactory,
allow_insert=False,
allow_delete=False,
allow_reorder=False,
auto_append=False,
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:

.. code-block:: python

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",
required=True,
values=["Work", "Home"],
)
# show checkboxes instead of selectbox
widget(address_type=CheckBoxFieldWidget)

class IFormSchema(interface.Interface):

table = schema.List(
title=u"Nested selection tree test",
value_type=DictRow(
title=u"tablerow",
schema=ITableRowSchema
)
)
widget(table=DataGridFieldFactory)

Working with plone.app.registry
-------------------------------

To use the field with plone.app.registry, you'll have to use
a version of the field that has PersistentField as it's base
class:

.. code-block:: python

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:

.. code-block:: javascript

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

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