Introduction

The plone.versioning (IVersionable) behavior is used for enabling the CMFEditions functionality for dexterity contents. It adds a changeNote-field to the edit- and add-forms and creates a new version when the content is edited, if enabled for the content type.

It's based on Products.CMFEditions. For listing the versions of an object use CMFEdtions' view versions_history_form or the history viewlet (see default @@view).

Usage

Just use the behavior plone.versioning (plone.app.versioningbehavior.behaviors.IVersionable) in your dexterity content type.

In your profiles/default/types/YOURTYPE.xml add the behavior plone.versioning:

<?xml version="1.0"?>
<object name="example.conference.presenter" meta_type="Dexterity FTI"
   i18n:domain="example.conference" xmlns:i18n="http://xml.zope.org/namespaces/i18n">

 <!-- enabled behaviors -->
 <property name="behaviors">
     <element value="plone.versioning" />
 </property>

</object>

The ``plone.versioning`` behavior just adds versioning support to your content type, but it does not enable it.

You have to set the "versioning" option in the Plone types control panel (/@@types-controlpanel) to either "Manual" or "Automatic" for activating versioning.

If you want to automatically enable versioning for your custom content types through generic setup you have to create a file "repositorytool.xml" in your gs profile (e.g. "profiles/default") with the following content:

<?xml version="1.0"?>
<repositorytool>
    <policymap>
        <type name="MyType">
            <policy name="at_edit_autoversion"/>
            <policy name="version_on_revert"/>
        </type>
        <type name="AnotherType">
            <policy name="at_edit_autoversion"/>
            <policy name="version_on_revert"/>
        </type>
    </policymap>
</repositorytool>
