A facade storage layer for Archetypes delegating to the Plone memberdata tool

Project Description


A facade storage for Archetypes which delegates to a Plone site’s Memberdata Tool for storing content item field values as memberdata properties.

This heavily relies on name magic. It is assumed that the correponding member and content instances have corresponding ids. Correspondence is established with the help of Products.PlonePAS.utils.[de]cleanId - the same way Plone 4 uses to keep track of member folders.

The use case driving its development has been to support custom Archetypes-based content types which can be used as home folders for members and mirroring some of the member properties. That way, people can change member properties by editing their home folder settings.

archetypes.memberdata is used in production on


In your Archetypes schema definition you can use the MemberPropertyField instead of a regular StringField to get and set the field’s value in a corresponding member property. Per default, a property with the same name as the field is used unless the member_property_id is set to point to a different property.

For other field types one can use MemberdataStorage as well as long as the data type can be handled by the member data tool.
