menhir.contenttype.folder 0.4

Dolmen contenttype extension : folder

Schema

A Folder does not have a particular schema. It uses only the IDescriptiveSchema from dolmen.app.content, exposing only the title and description attributes:

>>> from dolmen.content import schema
>>> from menhir.contenttype.folder import Folder
>>> print schema.bind().get(Folder)
[<InterfaceClass dolmen.app.content.interfaces.IDescriptiveSchema>]

The instanciation provides a fully functionnal folderish object:

>>> from zope.container.interfaces import IContainer
>>> folder = Folder(title=u"Some title")
>>> IContainer.providedBy(folder)
True

The Folder class inherits from the grokcore.content OrderedContainer: the keys of container are orderable (read mutable):

>>> from grokcore.content import OrderedContainer
>>> isinstance(folder, OrderedContainer)
True

Test in-situ

Setup the environment

>>> from zope.component.hooks import getSite
>>> root = getSite()

Create a Folder.

>>> from menhir.contenttype.folder import Folder
>>> root[u'folder'] = Folder()
>>> folder = root.get(u'folder')

Create a dummy content type, so that we can put dummy content in the folder.

>>> import dolmen.content as content
>>> class Dummy(content.Content):
...     content.name("Dummy")
...     # content.icon("dummy.png")

Fill the folder with some dummies.

>>> folder[u'books'] = Dummy(title=u"Books")
>>> folder[u'films'] = Dummy(title=u"Films")
>>> folder[u'music'] = Dummy(title=u"Music")

>>> folder[u'subfolder'] = Folder(title=u"SubFolder")
>>> folder[u'subfolder'][u'subfolder2'] = Folder(title=u'SubFolder Two')
>>> folder[u'subfolder'][u'bogus'] = Dummy(title=u'Bogus')
>>> folder[u'subfolder'][u'subfolder2'][u'hocus'] = Dummy(title=u"hocus")

Verify the contents are correct.

>>> dict([x for x in folder.items()])
{u'films': <menhir.contenttype.folder.Dummy object at ...>,
 u'books': <menhir.contenttype.folder.Dummy object at ...>,
 u'music': <menhir.contenttype.folder.Dummy object at ...>,
 u'subfolder': <menhir.contenttype.folder.folder.Folder object at ...>}

Let's take a look at it from the browser's point-of-view.

>>> from zope.publisher.browser import TestRequest
>>> from zope.component import getMultiAdapter
>>> request = TestRequest()

>>> view = getMultiAdapter((folder, request), name=folder.selected_view)
>>> view.__class__.__name__
'FolderListing'

>>> view.update()
>>> print view.render()
<div class="folder-listing">
  <h1>Content of the folder</h1>
  <div><table class="listing sortable">
  <thead>
    <tr>
      <th>Title</th>
      <th>Modification date</th>
    </tr>
  </thead>
  <tbody>
    <tr class="even">
      <td><a href="http://127.0.0.1/folder/books">books</a></td>
      <td></td>
    </tr>
    <tr class="odd">
      <td><a href="http://127.0.0.1/folder/films">films</a></td>
      <td></td>
    </tr>
    <tr class="even">
      <td><a href="http://127.0.0.1/folder/music">music</a></td>
      <td></td>
    </tr>
    <tr class="odd">
      <td><img src="http://127.0.0.1/@@/menhir-contenttype-folder-folder-IFolder-icon.png" alt="Folder" width="16" height="16" border="0" /> <a href="http://127.0.0.1/folder/subfolder">SubFolder</a></td>
      <td></td>
    </tr>
  </tbody>
</table></div>
</div>

We should have a look at the default view (index) as well.

>>> view = getMultiAdapter((folder, request), name='index')
>>> view.__class__.__name__
'SelectedView'

>>> view.update()
>>> print view.render()
<div class="folder-listing">
  <h1>Content of the folder</h1>
  <div><table class="listing sortable">
  <thead>
    <tr>
      <th>Title</th>
      <th>Modification date</th>
    </tr>
  </thead>
  <tbody>
    <tr class="even">
      <td><a href="http://127.0.0.1/folder/books">books</a></td>
      <td></td>
    </tr>
    <tr class="odd">
      <td><a href="http://127.0.0.1/folder/films">films</a></td>
      <td></td>
    </tr>
    <tr class="even">
      <td><a href="http://127.0.0.1/folder/music">music</a></td>
      <td></td>
    </tr>
    <tr class="odd">
      <td><img src="http://127.0.0.1/@@/menhir-contenttype-folder-folder-IFolder-icon.png" alt="Folder" width="16" height="16" border="0" /> <a href="http://127.0.0.1/folder/subfolder">SubFolder</a></td>
      <td></td>
    </tr>
  </tbody>
</table></div>
</div>

Lastly, let's change the folder layout to the full rendering view provided in this package.

>>> folder.selected_view = u'compositeview'
>>> view = getMultiAdapter((folder, request), name=folder.selected_view)
>>> view.__class__.__name__
'CompositeView'

>>> view.update()
>>> print view.content()
<div class="composite-view">
  <h1></h1>
  <div class="composite-body sequence-block">
    <div><form action="http://127.0.0.1" method="post"
      enctype="multipart/form-data">
  <h1>books</h1>
</form>
</div>
  </div>
  <div class="composite-body sequence-block">
    <div><form action="http://127.0.0.1" method="post"
      enctype="multipart/form-data">
  <h1>films</h1>
</form>
</div>
  </div>
  <div class="composite-body sequence-block">
    <div><form action="http://127.0.0.1" method="post"
      enctype="multipart/form-data">
  <h1>music</h1>
</form>
</div>
  </div>
  <div class="composite-body sequence-block">
    <div><div class="folder-listing">
  <h1>Content of the folder</h1>
  <div><table class="listing sortable">
  <thead>
    <tr>
      <th>Title</th>
      <th>Modification date</th>
    </tr>
  </thead>
  <tbody>
    <tr class="even">
      <td><img src="http://127.0.0.1/@@/menhir-contenttype-folder-folder-IFolder-icon.png" alt="Folder" width="16" height="16" border="0" /> <a href="http://127.0.0.1/folder/subfolder/subfolder2">SubFolder Two</a></td>
      <td></td>
    </tr>
    <tr class="odd">
      <td><a href="http://127.0.0.1/folder/subfolder/bogus">bogus</a></td>
      <td></td>
    </tr>
  </tbody>
</table></div>
