interface from z3c.formwidget.query and have a search() method. The easiest
|
||||
way to do this is generate one with one of:
|
||||
|
||||
* plone.formwidget.contenttree.PathSourceBinder(navigation_tree_query=None, **kw)
|
||||
* plone.formwidget.contenttree.ObjPathSourceBinder(navigation_tree_query=None, **kw)
|
||||
* plone.formwidget.contenttree.UUIDSourceBinder(navigation_tree_query=None, **kw)
|
||||
|
||||
Where ``navigation_tree_query`` is some restrictions that should be applied to
|
||||
any Catalog query. The rest of the arguments are used to form a filter (see source.py).
|
||||
|
||||
``PathSourceBinder`` and ``ObjPathSourceBinder`` store the selected object's
|
||||
path in the field value. This means that the link will be broken if the object
|
||||
is moved. ``UUIDSourceBinder`` stores UUID references, so will handle pages
|
||||
being moved.
|
||||
|
||||
If you do not want to filter the content tree whatsoever, there are some
|
||||
pre-baked instances too:
|
||||
|
||||
* plone.formwidget.contenttree.path_src_binder
|
||||
* plone.formwidget.contenttree.obj_path_src_binder
|
