z3c.tabular 0.6.2

Table with form support based on z3c.form and z3c.table for Zope3

This package provides a table implementation including form support for Zope3 based on z3c.form and z3c.table.

Issues

  • There is still an issue in README.txt sample, the samples are using nested <form> tags. Fix the sample and use real subform templates.

Form Table

The goal of this package is to offer a modular table rendering library which includes built in support for update forms. This will allow us to adapt items rendered as table row items to forms. This could prevent to use traversable exposed forms for such items. But this is just one of the benefits. See more below.

Form support

We need to setup the form defaults first:

>>> from z3c.form.testing import setupFormDefaults
>>> setupFormDefaults()

And load the formui confguration, which will make sure that all macros get registered correctly.

>>> from zope.configuration import xmlconfig
>>> import zope.component
>>> import zope.viewlet
>>> import zope.component
>>> import zope.app.publisher.browser
>>> import z3c.macro
>>> import z3c.template
>>> import z3c.formui
>>> xmlconfig.XMLConfig('meta.zcml', zope.component)()
>>> xmlconfig.XMLConfig('meta.zcml', zope.viewlet)()
>>> xmlconfig.XMLConfig('meta.zcml', zope.app.publisher.browser)()
>>> xmlconfig.XMLConfig('meta.zcml', z3c.macro)()
>>> xmlconfig.XMLConfig('meta.zcml', z3c.template)()
>>> xmlconfig.XMLConfig('configure.zcml', z3c.formui)()

And load the z3c.tabular configure.zcml:

>>> import z3c.tabular
>>> xmlconfig.XMLConfig('configure.zcml', z3c.tabular)()

Sample data setup

Let's create a sample container which we can use as our iterable context:

>>> from zope.container import btree
>>> class Container(btree.BTreeContainer):
...     """Sample container."""
...     __name__ = u'container'
>>> container = Container()

and set a parent for the container:

>>> root['container'] = container

and create a sample content object which we use as container item:

>>> import zope.interface
>>> import zope.schema
>>> class IContent(zope.interface.Interface):
...     """Content interface."""
...
...     title = zope.schema.TextLine(title=u'Title')
...     number = zope.schema.Int(title=u'Number')
>>> class Content(object):
...     """Sample content."""
...     zope.interface.implements(IContent)
...     def __init__(self, title, number):
...         self.__name__ = title.lower()
...         self.title = title
...         self.number = number

Now setup some items:

>>> container[u'first'] = Content('First', 1)
>>> container[u'second'] = Content('Second', 2)
>>> container[u'third'] = Content('Third', 3)

FormTable setup

The FormTable offers a sub form setup for rendering items within a form. Let's first define a form for our used items:

>>> from z3c.form import form
>>> from z3c.form import field
>>> class ContentEditForm(form.EditForm):
...     fields = field.Fields(IContent)

Now we can define our FormTable including the SelectedItemColumn:

>>> from z3c.table import column
>>> import z3c.tabular.table
>>> class ContentFormTable(z3c.tabular.table.SubFormTable):
...
...     subFormClass = ContentEditForm
...
...     def setUpColumns(self):
...         return [
...             column.addColumn(self, column.SelectedItemColumn,
...                              u'selectedItem', weight=1),
...             ]

And support the div form layer for our request:

>>> from z3c.formui.interfaces import IDivFormLayer
>>> from zope.interface import alsoProvides
>>> from z3c.form.testing import TestRequest
>>> request = TestRequest()
>>> alsoProvides(request, IDivFormLayer)

Now we can render our table. As you can see the SelectedItemColumn renders a link which knows hot to select the item:

>>> contentSubFormTable = ContentFormTable(container, request)
>>> contentSubFormTable.__name__ = 'view.html'
>>> contentSubFormTable.update()
>>> print contentSubFormTable.render()
<form action="http://127.0.0.1" method="post"
      enctype="multipart/form-data" class="edit-form"
      name="subFormTable" id="subFormTable">
  <div class="viewspace">
    <div>
    <table width="100%" border="0" cellspacing="0" cellpadding="0">
      <tr>
        <td valign="top">
          <div>
            <table class="contents">
              <thead>
                <tr>
                  <th>Name</th>
                </tr>
              </thead>
              <tbody>
                <tr class="even">
                  <td><a href="http://127.0.0.1/container/view.html?subFormTable-selectedItem-0-selectedItems=first">first</a></td>
                </tr>
                <tr class="odd">
                  <td><a href="http://127.0.0.1/container/view.html?subFormTable-selectedItem-0-selectedItems=second">second</a></td>
                </tr>
                <tr class="even">
                  <td><a href="http://127.0.0.1/container/view.html?subFormTable-selectedItem-0-selectedItems=third">third</a></td>
                </tr>
              </tbody>
            </table>
          </div>
        </td>
        <td valign="top">
        </td>
      </tr>
    </table>
  </div>
  </div>
  <div>
    <div class="buttons">
<input id="subFormTable-buttons-delete"
       name="subFormTable.buttons.delete"
       class="submit-widget button-field" value="Delete"
       type="submit" />
<input id="subFormTable-buttons-edit"
       name="subFormTable.buttons.edit"
       class="submit-widget button-field" value="Edit"
       type="submit" />
<input id="subFormTable-buttons-cancel"
       name="subFormTable.buttons.cancel"
       class="submit-widget button-field" value="Cancel"
       type="submit" />
    </div>
  </div>
</form>

Now we are ready to select an item by click on the link. We simulate this by set the relevant data in the request:

>>> selectRequest = TestRequest(form={
...     'subFormTable-selectedItem-0-selectedItems': 'second'})
>>> alsoProvides(selectRequest, IDivFormLayer)
>>> selectedItemTable = ContentFormTable(container, selectRequest)
>>> selectedItemTable.__name__ = 'view.html'
>>> selectedItemTable.update()
>>> print selectedItemTable.render()
<form action="http://127.0.0.1" method="post" enctype="multipart/form-data" class="edit-form" name="subFormTable" id="subFormTable">
  <div class="viewspace">
    <div>
    <table width="100%" border="0" cellspacing="0" cellpadding="0">
      <tr>
        <td valign="top">
          <div>
            <table class="contents">
  <thead>
    <tr>
      <th>Name</th>
    </tr>
  </thead>
  <tbody>
    <tr class="even">
      <td><a href="http://127.0.0.1/container/view.html?subFormTable-selectedItem-0-selectedItems=first">first</a></td>
    </tr>
    <tr class="selected odd">
      <td><a href="http://127.0.0.1/container/view.html?subFormTable-selectedItem-0-selectedItems=second">second</a></td>
    </tr>
    <tr class="even">
      <td><a href="http://127.0.0.1/container/view.html?subFormTable-selectedItem-0-selectedItems=third">third</a></td>
    </tr>
  </tbody>
</table>
          </div>
        </td>
        <td valign="top">

        </td>
      </tr>
    </table>

  </div>
  <div>
    <div class="buttons">

<input id="subFormTable-buttons-cancel" name="subFormTable.buttons.cancel" class="submit-widget button-field" value="Cancel" type="submit" />
    </div>
  </div>
</form>

Clicking the Edit button at the same time should hold the same result:

>>> selectRequest = TestRequest(form={
...     'subFormTable-selectedItem-0-selectedItems': 'second',
...     'subFormTable.buttons.edit': 'Edit'})
>>> alsoProvides(selectRequest, IDivFormLayer)

>>> selectedItemTable.update()

Unless allowEdit is False. In this case the editform won't appear.
