Default content types for Plone based on Dexterity

Latest Version: 1.2a3

http://jenkins.plone.org/job/kgs-plone.app.contenttypes-plone-5.0-python-2.7/badge/icon https://pypip.in/d/plone.app.contenttypes/badge.png https://pypip.in/v/plone.app.contenttypes/badge.png

Introduction

plone.app.contenttypes offers default content types for Plone based on Dexterity. This package replaces Products.ATContenttypes and will provide the default-types in Plone 5.

It contains the following types:

  • Folder
  • Document
  • News item
  • File
  • Image
  • Link
  • Event (Using behaviors from plone.app.event)
  • Collection (this already replaces plone.app.collection which is no longer needed then)

The main difference from a users perspective is that these types are extendable through-the-web. This means you can add or remove fields and behaviors using the control-panel "Dexterity Content Types" (/@@dexterity-types).

The aim is to mimick the default-types as closely as possible.

plone.app.contenttypes has been merged into the Plone 5.0 branch and will be shipped with the next Plone release: https://dev.plone.org/ticket/12344

Warning: Using plone.app.contenttypes on a site with existing content requires migrating the sites content. Please see the chapter "Migration". It can be used on a new site without problems.

Compatibility

Version 1.1b1 is tested with Plone 4.3.x. The versions 1.1.x will stay compatible with Plone 4.3.x.

For support of Plone 4.1 and 4.2 please use version 1.0.x. Please note that they do not provide the full functionality.

The future versions 1.2.x will be compatible with Plone 5 only and add support for plone.app.widgets

Installation

Add this line in the eggs section of your buildout.cfg

eggs =
    ...
    plone.app.contenttypes

If you have a Plone site with mixed Archetypes and Dexterity content use the extra requirement atrefs.

eggs =
    ...
    plone.app.contenttypes [atrefs]

This will also install the package plone.app.referenceablebehavior that allows you to reference dexterity-based content from archetypes-based content. You will have to enable the behavior plone.app.referenceablebehavior.referenceable.IReferenceable for all types that need to be referenced by Archetypes-content.

What happens to existing content?

If you install plone.app.contenttypes in a existing site all Archetypes-based content of the default types still exists and can be viewed but can't be edited. On installation plone.app.contenttypes removes the type-definitions for the old default-types like this:

<object name="Document" remove="True" />

They are then replaced by new Definitions:

<object meta_type="Dexterity FTI" name="Document" />

To make the existing content editable again you need to migrate it to Dexterity (please see the section on migration) or uninstall plone.app.contenttypes (see the section on uninstalling).

Archetypes-based content provided by add-ons (e.g. Products.PloneFormGen) will still work since only the default-types are replaced.

If you install plone.app.contenttypes on a fresh site (i.e. when no content has been edited or added) the usual default-content (Events, News, Members...) will be created as dexterity-content.

Uninstalling

To remove plone.app.contenttypes and return full functionality to old content and restore the AT-based default-types you have to install the import step "Types Tool" of the current base profile. Follow the following steps:

  • in the ZMI navigate to portal_setup and the tab "import"
  • in "Select Profile or Snapshot" leave "Current base profile (<Name of your Plonesite>)" selected. This is usually Products.CMFPlone
  • select the Types Tool (usually Step 44)
  • click "import selected steps"

Any content you created based on plone.app.contenttypes will not be editable until you reinstall plone.app.contenttypes.

Dependencies

  • plone.app.dexterity >= 2.0.7. Dexterity is shipped with Plone 4.3.x. Version pinns for Dexterity are included in Plone 4.2.x. For Plone 4.1.x you need to pin the correct version for Dexterity in your buildout. See Installing Dexterity on older versions of Plone.
  • plone.dexterity >= 2.2.1. Olders version of plone.dexterity break the rss-views because plone.app.contenttypes uses behaviors for the richtext-fields.
  • plone.app.event >= 1.1b1. This provides the behaviors used for the event-type.
  • plone.app.portlets >= 2.5a1. In older version the event-portlet will not work with the new event-type.

These are the version-pinns for Plone 4.3.3:

[buildout]
versions = versions

[versions]
plone.app.event = 1.1b1
plone.app.portlets = 2.5a1

Plone-versions before 4.3.3 need to pinn more packages:

[buildout]
versions = versions

[versions]
plone.dexterity = 2.2.1
plone.app.dexterity = 2.0.11
plone.schemaeditor = 1.3.5
plone.app.event = 1.1b1
plone.app.portlets = 2.5a1

Migration

To migrate your existing content from Archetypes to Dexterity use the form at /@@atct_migrator.

For migrations to work you need at least Products.contentmigration = 2.1.3 (part of Plone since Plone 4.2.5) and plone.app.intid (part of Plone since Plone 4.1.0).

Migrating Archetypes-based content to plone.app.contenttypes

plone.app.contenttypes can migrate the following default types:

  • Document
  • Event
  • File
  • Folder
  • Image
  • Link
  • News Item
  • Collection

The following non-default types will also be migrated:

  • The AT-based Event-type provided by plone.app.event
  • The DX-based Event-type provided by plone.app.event
  • The Event-type provided by plone.app.contenttypes until version 1.0
  • News Items with blobs (provoded by https://github.com/plone/plone.app.blob/pull/2)
  • Files and Images without blobs
  • AT-based collection provided by plone.app.collection

Migrations that might come in a future version:

  • from ATTopic to Collections

Please note that migrating versions of content is not supported. Only the current state of items is migrated without any content- or workflow-history.

Migrating content that is translated with LinguaPlone

Since LinguaPlone does not support Dexterity you need to migrate from LinguaPlone to plone.app.multilingual (http://pypi.python.org/pypi/plone.app.multilingual). The migration from Products.LinguaPlone to plone.app.multilingual should happen before the migration from Archetypes to plone.app.contenttypes. For details on the migration see http://pypi.python.org/pypi/plone.app.multilingual#linguaplone-migration

Migrating from old versions of plone.app.contenttypes

Before version 1.0a2 the content-items did not implement marker-interfaces. They will break in newer versions since the views are now registered for these interfaces (e.g. plone.app.contenttypes.interfaces.IDocument). To fix this you can call the view /@@fix_base_classes on your site-root.

Since plone.app.contenttypes 1.1a1, the Collection type uses the new Collection behavior and the Event type utilizes behaviors from plone.app.event. In order to upgrade:

  1. First run the default profile (plone.app.contenttypes:default) or reinstall plone.app.contenttypes
  2. Then run the upgrade steps.

Migrating default-content that was extended with archetypes.schemaextender

The migration should warn you if any of your types are extended with archetypes.schemaextender. The data contained in these fields will be lost.

You need to implement a custom migration for your types and dexterity-behaviors for the functionality provided by the schemaextenders. This is an advanced development task and beyond the scope of this documentation.

Migrating custom content

Custom content-types will not be touched by the migration plone.app.contenttypes and will continue to work as expeced. However if you'd like to migrate your content-types to Dexterity (you'll have to create these types in Dexterity first) you might want to have a look at the code of plone.app.contenttypes.migration.migration.NewsItemMigrator as a blueprint.

Widgets

When used in Plone 4.x plone.app.contenttypes uses the default z3c.form widgets. All widgets work as they used to with Archetypes except for the keywords-widget for which a simple linesfield is used.

It is recommended to use plone.app.widgets to switch to the widgets that will be used in Plone 5.

How to override widgets

To override the default keywords-widgets with a nicer widget you can use the package collective.z3cform.widgets.

Add collective.z3cform.widgets to your buildout and in your own package register the override in your configure.zcml:

<adapter factory=".subjects.SubjectsFieldWidget" />

Then add a file subjects.py

# -*- coding: UTF-8 -*-
from collective.z3cform.widgets.token_input_widget import TokenInputFieldWidget
from plone.app.dexterity.behaviors.metadata import ICategorization
from plone.app.z3cform.interfaces import IPloneFormLayer
from z3c.form.interfaces import IFieldWidget
from z3c.form.util import getSpecification
from z3c.form.widget import FieldWidget
from zope.component import adapter
from zope.interface import implementer


@adapter(getSpecification(ICategorization['subjects']), IPloneFormLayer)
@implementer(IFieldWidget)
def SubjectsFieldWidget(field, request):
    widget = FieldWidget(field, TokenInputFieldWidget(field, request))
    return widget

Once you install collective.z3cform.widgets in the quickinstaller, the new widget will then be used for all types.

Information for Addon-Developers

Design decicions

The schemata for the types File, Image and Link are defined in xml-files using plone.supermodel. This allows the types to be editable trough the web. The types Document, News Item, Folder and Event have no schemata but only use behaviors to provide their fields.

Installation as a dependency from another product

If you want to add plone.app.contenttypes as a dependency from another products use the profile plone-content in your metadata.xml to have Plone populate a new site with DX-based default-content.

<metadata>
  <version>1</version>
    <dependencies>
        <dependency>profile-plone.app.contenttypes:plone-content</dependency>
    </dependencies>
</metadata>

If you use the profile default then the default-content in new sites will still be Archetypes-based. You'll then have to migrate that content using the migration-form @@atct_migrator or delete it by hand.

Extending the types

You have several options:

  1. Extend the types through-the-web by adding new fields or behaviors in the types-controlpanel /@@dexterity-types.

  2. Extend the types with a custom type-profile that extends the existing profile with behaviors, or fields.

    You will first have to add the type to your [yourpackage]/profiles/default/types.xml.

    <?xml version="1.0"?>
    <object name="portal_types" meta_type="Plone Types Tool">
      <object name="Folder" meta_type="Dexterity FTI" />
    </object>
    

    Here is an example that enables the image-behavior for Folders in [yourpackage]/profiles/default/types/Folder.xml:

    <?xml version="1.0"?>
    <object name="Folder" meta_type="Dexterity FTI">
     <property name="behaviors" purge="False">
      <element value="plone.app.contenttypes.behaviors.leadimage.ILeadImage"/>
     </property>
    </object>
    

    By adding a schema-definition to the profile you can add fields.

    <?xml version="1.0"?>
    <object name="Folder" meta_type="Dexterity FTI">
     <property name="model_file">your.package.content:folder.xml</property>
     <property name="behaviors" purge="False">
      <element value="plone.app.contenttypes.behaviors.leadimage.ILeadImage"/>
     </property>
    </object>
    

    Put the schema-xml in your/package/content/folder.xml (the folder content needs a __init__.py)

    <model xmlns:security="http://namespaces.plone.org/supermodel/security"
           xmlns:marshal="http://namespaces.plone.org/supermodel/marshal"
           xmlns:form="http://namespaces.plone.org/supermodel/form"
           xmlns="http://namespaces.plone.org/supermodel/schema">
      <schema>
        <field name="teaser_title" type="zope.schema.TextLine">
          <description/>
          <required>False</required>
          <title>Teaser title</title>
        </field>
        <field name="teaser_subtitle" type="zope.schema.Text">
          <description/>
          <required>False</required>
          <title>Teaser subtitle</title>
        </field>
        <field name="teaser_details" type="plone.app.textfield.RichText">
          <description/>
          <required>False</required>
          <title>Teaser details</title>
        </field>
      </schema>
    </model>
    

For more complex features you should create custom behaviors and/or write your own content-types. For more information on creating custom dexterity-types or custom behaviors to extend these types with read the dexterity documentation.

Differences to Products.ATContentTypes

  • The image of the News Item is not a field on the contenttype but a behavior that can add a image to any contenttypes (similar to http://pypi.python.org/pypi/collective.contentleadimage)
  • All richtext-fields are also provided by a reuseable behavior.
  • The functionality to transform (rotate and flip) images has been removed.
  • There is no more field Location. If you need georeferenceable consider using collective.geo.behaviour
  • The link on the image of the newsitem triggers an overlay
  • The link-type now allows the of the variables ${navigation_root_url} and ${portal_url} to construct relative urls.
  • The keywords-widget is not implemented and is replaced by a simple lines-widget unless you override it or use plone.app.widgets. Please see the section on widgets.

Toubleshooting

Please report issues in the bugtracker at https://github.com/plone/plone.app.contenttypes/issues.

ValueError on installing

When you try to install plone.app.contenttypes < 1.1a1 in a existing site you might get the following error:

  (...)
  Module Products.GenericSetup.utils, line 509, in _importBody
  Module Products.CMFCore.exportimport.typeinfo, line 60, in _importNode
  Module Products.GenericSetup.utils, line 730, in _initProperties
ValueError: undefined property 'schema'

Before installing plone.app.contenttypes you have to reinstall plone.app.collection to update collections to the version that uses Dexterity.

Branches

The master-branch supports Plone 5 only. From this 1.2.x-releases will be cut.

The 1.1.x-branch supports Plone 4.3.x. From this 1.1.x-releases will be cut.
