A queriable source for accessing users and/or groups
Project description
Introduction
This package provides a queriable sources (vocabularies) that return PAS users, groups or principals (both users and groups).
They are registered as named vocabularies, so you can do:
class IMyInterface(Interface):
users = schema.Choice(title=u"Users",
vocabulary="plone.principalsource.Users")
groups = schema.Choice(title=u"Groups",
vocabulary="plone.principalsource.Groups")
principals = schema.Choice(title=u"Principals",
vocabulary="plone.principalsource.Principals")
The underlying source (see source.py) implements the IQuerySource interface from z3c.formwidget.query. This means that it can be used for a query-select widget, including the one in plone.formwidget.autocomplete.
A note about unicode
The source attempts to make it safe to do a __contains__ check, a getTerm() lookup, and searches using unicode strings. This is somewhat constrained by the underlying plugins. In particular, the standard ZODBGroups plugin is incapable of searching for groups with unicode titles or ids, and returns a list of all groups if passed a unicode string. As such, the source forces all unicode strings used to search for groups to UTF-8 (searching for users is unaffected).
Also, remember that tokens should be 7-bit ASCII strings. getTermByToken() is forgiving in that it silently encodes a unicode string to utf-8, but really you should only pass unicode to this method.
