Uberselection widget
This package provides a query source compatible with z3c.formwidget.query which combines to an uberselection widget for the z3c.form form generation framework.
The native value type for the widget is Archetypes UID collections.
Example:
>>> from plone.z3cform.uberselect import \ ... ArchetypesContentSourceBinder>>> class ISelection(interface.Interface): ... items = schema.Set( ... title=u"Selection", ... description=u"Search for content.", ... value_type=schema.Choice( ... source=ArchetypesContentSourceBinder() ... ) ... )
A recipe to store references as persistent.wref.WeakRef instead of UID is to use the uid2wref adapter between the form and the context.
>>> from plone.z3cform.uberselect import uid2wref>>> Factory = uid2wref(ISelection['items'])
To store weak references instead of UIDs you would register such a factory as a component adapting the context. The factory automatically provides the interface which defines the field.
