menhir.contenttype.folder 0.4

模式

Folder没有特定的架构。它只使用 IDescriptiveSchema来自dolmen.app.content，仅显示 title和description属性：

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

实例提供了一个功能齐全的folderish对象：

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

Folder类继承自grokcore.content orderedcontainer：容器的键是orderable（read mutable）：

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

现场测试

设置环境

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

创建文件夹。

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

创建虚拟内容类型，以便我们可以将虚拟内容放在文件夹中。

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

在文件夹里放些傻瓜。

>>> 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")

确认内容正确。

>>> 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 ...>}

让我们从浏览器的角度来看一下。

>>> 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>

我们还应该看看默认视图（索引）。

>>> 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>

最后，我们将文件夹布局更改为完整的呈现视图 在这个包裹里提供。

>>> 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>
<BLANKLINE>
