In the ModelAdmin I use a get_form() to test for conditions on the object. Specifically, if this item has been published then make it read_only. You should be able to test for users as well.
I had to add the try/except in order to add new objects because obj.published doesn't exist on a new object. See: https://docs.djangoproject.com/en/1.5/ref/contrib/admin/#django.contrib.admin.ModelAdmin.get_form Here is a snippet: def get_form(self, request, obj=None, **kwargs): try: if obj.published: self.readonly_fields = ['prj_name','published','schema_code','data_name','description','sem_attr','resource_uri','asserts', 'simple_units','coded_units','normal_status','reference_ranges','min_inclusive','max_inclusive', 'min_exclusive','max_exclusive','total_digits','fraction_digits','magnitude','error','accuracy','magnitude_status',] except (AttributeError, TypeError) as e: self.readonly_fields = ['published','schema_code'] return super(DvQuantityAdmin, self).get_form(request, obj, **kwargs) On Wed, Oct 9, 2013 at 11:06 AM, Victor <[email protected]> wrote: > Yes, I know but unfortunately if in Admin Site you say that a user cannot > Add, Delete, and Modify a model if that user is connected he/she doesn't > see the model itself in the list but only those models for which it has > some kind of permission.
