Permission to view, but not to change! - Django
You can do this by following way:
1)You can make the fields read only if the object has been created.But doing this noone will be able to change the fields
2)You can use databrowse
3)You can use form validation ,if user is not in the selected list throw validation error if any field is changed
4)you can create a view ,if user is in your list then redirect it to normal flow or else redirect him to simple html readonly page 
5)Use jquery to make the fields readonly is user is not in the list  and override the save method to check any smartness.In your save method you throw error any form has changed and user is not in your list.username=request.user.username
is it possible to give users the permission to view, but not to change or delete.
currently in the only permissions I see are "add", "change" and "delete"... but there is no "read/view" in there.
I really need this as some users will only be able to consult the admin panel, in order to see what has been added in.
