Plone Features

A significant strength of Plone is its flexibility.

Plone Entwicklung

Plone beruht auf der Zope3 Component Architecture

• ZCML: XML basierte Language zur Konfiguration der Komponentent
• ZCA: pluggable system interfaces, adapters, utilities and registries.

ZCML

Zope Configuration Mark-up Language

<configure
    xmlns="http://namespaces.zope.org/zope"
    xmlns:browser="http://namespaces.zope.org/browser"
    i18n_domain="my.package">
    <configure package="plone.app.content.browser">
      <browser:page
          for="Products.CMFCore.interfaces._content.IFolderish"
          class="my.package.browser.foldercontents.MyFolderContentsView"
          name="folder_contents"
          template="folder_contents.pt"
          layer="my.package.interfaces.IMyPackageLayer"
          permission="cmf.ListFolderContents"
      />
  </configure>
</configure>

Interfaces (vs. Duck-Typing)

from zope.interface import implements
from zope.interface import Interface

class IPony(Interface).
    pass

class SweetSurprise(ContentItem):
    implements(IPony, ICookie)
...
if ICookie.providedBy(object):
    # do stuff

Adapter (vs. Mixin Classes)

@implementer(ILeadImage)
@adapter(IDexterityContent)
class LeadImage(object):

    def __init__(self, context):
        self.context = context

<adapter
    for=".shop.MyShoppableItemType"
    provides=".interfaces.IProductImageProvider"
    factory=".images.FolderishProductImageProvider"
    />

Utilities (vs. monkey-patching)

class AssetAssignmentTool(object):
    """ Factory providing CRUD oparations for project assets """

    @memoize
    def read(self, uuid, key=None):
        data = api.find(...)
        return data

tool = getUtility(IAssetAssignmentTool)
data = tool.read()

<!-- Tool providing utility functions for asset storage manipulation -->
<utility
    factory=".tool.AssetAssignmentTool"
    provides=".interfaces.IAssetAssignmentTool"/>

Generic Setup (vs. Paste to custom folder)

Generic Setup steps

• registrieren CSS files
• registrieren Javascript files
• setzen Properties und Konfigurationseinträge
• registrieren Portlets (mobile Content Blöcke)
• registrieren search query indexes für den Katalog

Generic Setup (Beispiele)

<genericsetup:registerProfile
      name="default"
      title="Plone Go Mobile"
      directory="profiles/default"
      description='Mobile CMS add-on'
      provides="Products.GenericSetup.interfaces.EXTENSION"/>

<genericsetup:upgradeStep
      title="Remove LDAP PAS Plugin"
      description="Execute this upgrade after the plonesite upgrade"
      handler=".v4.upgrade_pas"
      />

Events

<subscriber
    for="Products.PlonePAS.events.UserLoggedOutEvent"
    handler=".mymodule.clear_extra_cookies_on_logout"
    />

def clear_extra_cookies_on_logout(event):
    # What event contains depends on the
    # triggerer of the event and event class
    request = event.object.REQUEST
