With the help of this package you can create tables inside forms. Think on a folder listing where you have a checkbox on the first column and you can check the rows you want to modify. Such modifcations are for example:

  • edit
  • delete
  • change workflow state

megrok.z3cform.tabular is based on these existing megrok packages:

  • megrok.layout
  • megrok.z3ctable
  • megrok.z3cform.base
  • megrok.z3cform.ui


First we have to setup a container with some objects.

>>> from zope.app.testing.functional import getRootFolder
>>> root = getRootFolder()
>>> from zope.app.container import btree
>>> class Container(btree.BTreeContainer):
...     """Sample container."""
...     __name__ = u'container'
>>> container = Container()
>>> root['container'] = container
>>> class Content(object):
...     """Sample content."""
...     def __init__(self, title, number):
...         self.title = title
...         self.number = number
>>> container[u'first'] = Content('First', 1)
>>> container[u'second'] = Content('Second', 2)
>>> container[u'third'] = Content('Third', 3)
>>> len(container)

Ok now we have a container with three objects in it. Now we can create a tabular view for this container:

>>> from megrok.z3cform.tabular import FormTable
>>> import grokcore.component as grok
>>> from megrok.z3cform.base import button, extends
>>> class FormTableView(FormTable):
...     grok.context(Container)
...     extends(FormTable)
...     @button.buttonAndHandler(u'ChangeWorkflowState')
...     def handleChangeWorkflowState(self, action):
...         print 'success'
...     def render(self):
...         return self.renderFormTable()
>>> grok.testing.grok_component('formtableview', FormTableView)
>>> from megrok.z3ctable import table, CheckBoxColumn, NameColumn
>>> class CheckBox(CheckBoxColumn):
...     grok.name('checkBox')
...     grok.context(Container)
...     table(FormTableView)
>>> grok.testing.grok_component('checkbox', CheckBox)
>>> class Name(NameColumn):
...     grok.name('name')
...     grok.context(Container)
...     table(FormTableView)
>>> grok.testing.grok_component('name', Name)

Ok now we can call the FormTableView on the container. We should see a table with three rows and two columns. There is a default Cancel button and our custom ChangeWorkflowState button.

>>> from zope.publisher.browser import TestRequest
>>> request = TestRequest()
>>> from zope.component import getMultiAdapter
>>> formtableview = getMultiAdapter((container, request), name="formtableview")
>>> formtableview
<FormTableView 'formtableview'>
>>> formtableview.update()
>>> print formtableview()
<form action="" method="post"
enctype="multipart/form-data" class="edit-form"
name="formTable" id="formTable">
<div class="viewspace">
<div class="tabluarTable">
<table class="contents">
<tr class="even">
<td><input type="checkbox" class="checkbox-widget" name="formTable-checkBox-1-selectedItems" value="first"  /></td>
<tr class="odd">
<td><input type="checkbox" class="checkbox-widget" name="formTable-checkBox-1-selectedItems" value="second"  /></td>
<tr class="even">
<td><input type="checkbox" class="checkbox-widget" name="formTable-checkBox-1-selectedItems" value="third"  /></td>
<div class="tabluarForm">
<div class="buttons">
<input id="formTable-buttons-cancel"
class="submit-widget button-field" value="Cancel"
type="submit" />
<input id="formTable-buttons-changeworkflowstate"
class="submit-widget button-field"
value="ChangeWorkflowState" type="submit" />

This package works nicely with megrok.layout. There are some additional BaseClasses available. Please take a look on the tests.
