plone.directives.dexterity 1.0

Content classes

Content extending the Dexterity ‘Item’ and ‘Container’ base classes can be grokked in order to register a factory and/or ZMI add permission.

For example:

from plone.directives import dexterity
from plone.directives import form
from five import grok
from zope import schema

class IPage(form.Schema):

    title = schema.TextLine(title=u"Title")

    description = schema.Text(title=u"Description",
                          description=u"Summary of the body")

    body = schema.Text(title=u"Body text",
                       required=False,
                       default=u"Body text goes here")

    details = schema.Text(title=u"Details",
                          required=False)

class FSPage(dexterity.Item):
    grok.implements(IPage)
    grok.name('example.page')

    def __init__(self, id=None, title=None, description=None, body=None, details=None):
        self.id = id # required - or call super() with this argument
        self.title = title
        self.description = description
        self.body = body
        self.details = details

This will register a factory utility if one is not already present with the name ‘example.fspage’.

You can also use the ‘add_permission()’ directive to cause the type to be registered as a Zope 2 content class, in the same way that the <five:registerClass /> directive does:

class ZopeTwoItem(dexterity.Item):
    grok.implements(IPage)
    dexterity.add_permission('cmf.AddPortalContent')
    portal_type = 'example.zopetwopage'

However, for most content types, this will be unnecessary.

Forms

To create a Dexterity add-, edit- or display form for your type, use the AddForm, EditForm or DisplayForm base classes. For example:

from plone.directives import dexterity
from plone.directives import form
from five import grok
from zope import schema

class IPage(form.Schema):

    title = schema.TextLine(title=u"Title")

    description = schema.Text(title=u"Description",
                          description=u"Summary of the body")

    body = schema.Text(title=u"Body text",
                       required=False,
                       default=u"Body text goes here")

    details = schema.Text(title=u"Details",
                          required=False)

class View(dexterity.DisplayForm):
    """The view. May will a template from <modulename>_templates/view.pt,
    and will be called 'view' unless otherwise stated.
    """
    grok.require('zope2.View')
    grok.context(IPage)

class Edit(dexterity.EditForm):
    """A standard edit form.
    """
    grok.context(IPage)

    def updateWidgets(self):
        super(Edit, self).updateWidgets()
        self.widgets['title'].mode = 'hidden'

These forms are grokked in a manner that is similar to plone.directives.form, and support custom template associations. Please note, however:

• When using dexterity.AddForm as a base, you must use the grok.name() directive to give the name of the add view. Usually, this is the same as the name of the Factory Type Information object.

• When using dexterity.EditForm as a base, you must use grok.context() and supply a Dexterity content type interface as an argument. This is to allow proper re-use of types.
