Readonly models in Django admin interface?

Question

How can I make a model completely read-only in the admin interface? It\'s for a kind of log table, where I\'m using the admin features to search, sort, filter etc, but there

Answer 1

If you want the user become aware that he/she cannot edit it, 2 pieces are missing on the first solution. You have remove the delete action!

class MyAdmin(ModelAdmin)
    def has_add_permission(self, request, obj=None):
        return False
    def has_delete_permission(self, request, obj=None):
        return False

    def get_actions(self, request):
        actions = super(MyAdmin, self).get_actions(request)
        if 'delete_selected' in actions:
            del actions['delete_selected']
        return actions

Second: the readonly solution works fine on plain models. But it does NOT work if you have an inherited model with foreign keys. Unfortunately, I don't know the solution for that yet. A good attempt is:

Whole model as read-only

But it does not work for me either.

And a final note, if you want to think on a broad solution, you have to enforce that each inline has to be readonly too.
