[GeoNode-users] developpement: Modifying permission behavior and data visibility in Geonode

Tue Jun 9 07:01:34 PDT 2015

Hugo,

Based on what I understand, the best path forward is to have a
view_metadata permission that you use to enforce the behavior you want.
Assigning a new meaning to the existing permission may be problematic for
other users with different needs (for example where metadata is sensitive
information).

The place where we want to get to, is to allow uploaders to restrict any
actions they want, but give the end user buttons to request permissions (to
view if they cannot view, to download if they can only view, to edit if the
can only download) to encourage a conversation between uploaders and users
and provide a workflow to allow access to information when it is needed.

The changes you make would be good candidates for inclusion in the main
version of GeoNode so others can benefit in the future. Hopefully others
(Paolo?) can chime in with more specific feedback.

Best,
Ariel.
