Back Reference Field/Widget for Plone/Archetypes
Use it like a field is supposed to be used. Its almost similar to ReferenceField, ReferenceWidget/ ReferenceBrowserWidget.
Archetypes Referenceable API offers already back-references, the field/widget allows to visualize them like forward references. The relationship (name) of the reference must be the same as on the forward reference field given.
Usage for ArchGenXML/ UML
in your UML tool create a relation between 2 classes and make the ‘to’ end of i the assocation navigable (such a beast is provided in the sample dir).
add the tagged value backreferences_support to your model and set it to 1.
restart your zope and try it out
BackReferenceField for Archetypes.
This is the counterpart to the ReferenceField. When you have a relation that is managed by a ReferenceField, you can define at the reference’s target object a BackReferenceField and a BackReferenceWidget, that alows you to navigate back and also add references to the same relation from the other side
You have to install it via portal_setup because it has skin elements (the widget templates).
Works with Plone 3 and 4.
