Factory Type Information (FTI)#

A content type is defined by creating a Factory Type Information (FTI) object.

To create an FTI in a GenericSetup profile, add the content type to the list in types.xml. For example, this adds the standard Plone page (Document) content type:

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

Then add a file to the types directory with the same name. In this example, the file is types/Document.xml and contains this XML:

<?xml version="1.0" encoding="utf-8"?>
<object xmlns:i18n="http://xml.zope.org/namespaces/i18n"
        meta_type="Dexterity FTI"
        name="Document"
        i18n:domain="plone"
>

  <!-- Basic properties -->
  <property name="title"
            i18n:translate=""
  >Page</property>
  <property name="description"
            i18n:translate=""
  />

  <property name="allow_discussion">False</property>
  <property name="factory">Document</property>
  <property name="icon_expr">string:contenttype/document</property>

  <!-- Hierarchy control -->
  <property name="allowed_content_types" />
  <property name="filter_content_types">True</property>
  <property name="global_allow">True</property>

  <!-- Schema, class and security -->
  <property name="add_permission">plone.app.contenttypes.addDocument</property>
  <property name="klass">plone.app.contenttypes.content.Document</property>
  <property name="model_file">plone.app.contenttypes.schema:document.xml</property>
  <property name="model_source" />
  <property name="schema" />

  <!-- Enabled behaviors -->
  <property name="behaviors"
            purge="false"
  >
    <element value="plone.namefromtitle" />
    <element value="plone.allowdiscussion" />
    <element value="plone.excludefromnavigation" />
    <element value="plone.shortname" />
    <element value="plone.dublincore" />
    <element value="plone.richtext" />
    <element value="plone.relateditems" />
    <element value="plone.versioning" />
    <element value="plone.tableofcontents" />
    <element value="plone.locking" />
  </property>

  <!-- View information -->
  <property name="add_view_expr">string:${folder_url}/++add++Document</property>
  <property name="default_view">document_view</property>
  <property name="default_view_fallback">False</property>
  <property name="immediate_view">view</property>
  <property name="view_methods">
    <element value="document_view" />
  </property>

  <!-- Method aliases -->
  <alias from="(Default)"
         to="(dynamic view)"
  />
  <alias from="edit"
         to="@@edit"
  />
  <alias from="sharing"
         to="@@sharing"
  />
  <alias from="view"
         to="(selected layout)"
  />

  <!-- Actions -->
  <action action_id="view"
          category="object"
          condition_expr=""
          icon_expr="string:toolbar-action/view"
          title="View"
          url_expr="string:${object_url}"
          visible="True"
          i18n:attributes="title"
  >
    <permission value="View" />
  </action>
  <action action_id="edit"
          category="object"
          condition_expr="not:object/@@plone_lock_info/is_locked_for_current_user|python:True"
          icon_expr="string:toolbar-action/edit"
          title="Edit"
          url_expr="string:${object_url}/edit"
          visible="True"
          i18n:attributes="title"
  >
    <permission value="Modify portal content" />
  </action>

</object>

The name attribute on the root element in the XML must match the name in the filename and the name listed in types.xml.

Set the i18n:domain to the i18n domain which includes translations for this content type. This is usually the same as the name of the Python package which contains the content type.

Global FTI properties#

The XML sets a number of FTI properties that are used globally, in both Classic UI and Volto:

action elements: Defines additional actions which are available for this content type.
add_permission: ID of the permission controlling whether the current user has permission to add this content type.
allow_discussion: Boolean. Controls whether Plone's commenting system is enabled by default for this content type.
allowed_content_types: List of content types which can be added inside this one. Only used if filter_content_types is True.
behaviors: List of behaviors enabled for this content type.
description: Short description displayed in the user interface.
factory: Name of the factory adapter used to create new instances of the content type. Usually the same as the content type name.
filter_content_types: Boolean. Controls which content types can be added inside this one. If True, allow only the types listed in allowed_content_types. If False, allow any content type that the user has permission to add.
global_allow: Boolean. Set to True to allow adding the content type anywhere in the site where the user has permission. Set to False to only allow adding it inside other content types that include this one in allowed_content_types.
klass: Dotted path to the Python class for this content type.
model_file: Location of an XML file to load as the content type's schema. This is an alternative to schema and model_source.
model_source: Inline XML schema for the content type. This is an alternative to schema and model_file.
schema: Dotted path to the Python schema for this content type. One of model_file, model_source, and schema must be set. schema is the most commonly used.
title: The name of the content type displayed in the user interface.

Classic UI only FTI properties#

The following FTI properties are used only in Classic UI:

add_view_expr: TALES expression returning the URL of the form to add a new item of this content type.
alias elements: Controls a mapping from URL to views. It's not common to change this.
default_view: Name of the default view used to display this content type.
default_view_fallback: Boolean. If True, the default_view will be used if the assigned view is not found.
icon_expr: TALES expression returning the name of one of the registered icons. See Icons.
immediate_view: Name of the view alias to display after a new item is added.
view_methods: List of views which can be selected to display this content type.
