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

[FERRARI Hugo]

Hello everyone,
I have installed a complete geonode instance on a developpement server.
I want  to change thebehaviorofthesoftware  to make it fit the need of 
the institution I work for.
So i'm looking for some advices because  I didn't manage to code it yet.

My aim to separate metada access from the data access.
That  is to make all the layers uploaded in geoserver VISIBLE for all 
users (logged or not) but only in the layer-list page , not on the 
layer-detail page .
If you click on any specific layer in the layer-list (or document-list 
because i want the same behavior for both), you get the layer detail so 
you what will see is:

- In the case you have the view_resourcebase permission (who can see it 
?), you will see the current template corresponding to 
layer_detail.html: both access to datas and metadatas.
- In the other case if you don't have the view_resourcebase permission, 
you 'll only have access to metadatas's ressource (that means a template 
similar to layer_detail.html but Instead of the geoexplorer frame you 
sould have a "permission denied" message, but the possibility to 
retrieve metadata).

It's quite simple to make all the layers visible in the layer list, 
whoever is logged in (you just have to modify SKIP_PERMS_FILTERS in 
settings.py AND read_list function in module api/authorisation.py).
but the actual behavior is to catch a 403 http error when trying to view 
the layer detail.
Modifying the 403.html template does not seems to be the good way to 
process.
I don't think it is necessary to modify geonode's database model because 
the view_ressource permission  is enough, considering that  viewing the 
ressource is equivalent to having access to the data (even if you can't 
download it). There's no need to add a new kind of permissions, as far 
as I can guess.
What is prefered is not throwing a 403 error but just the 
layer_detail.html template modified to get only metadatas.

I hope the explanation was clear enough,
Thanks for your advices
Hugo FERRARI

PS
Does it correspond to the actual geonode developpement policy ?
Datas and metada are strongly linked in this software.
Could this functionnality be interresting for any other geonode users?
