#17749 closed Cleanup/optimization (fixed)

Admin documentation on views suggests poor way of adding extra_context

Reported by: chrisdpratt Owned by: nobody
Component: Documentation Version: master
Severity: Normal Keywords: admin, documentation, docs
Cc: Triage Stage: Accepted
Has patch: yes Needs documentation: no
Needs tests: no Patch needs improvement: no
Easy pickings: yes UI/UX: no


As reference see:

If you pass my_context for extra_context in this way, it completely drops any existing context passed in from a subclass also overriding this method. This could lead to a confusing scenario in which Django is seemingly ignoring extra_context. One better approach would be:

def change_view(self, request, object_id, extra_context=None):
    extra_context = extra_context or {}
    extra_context['osm_data'] = self.get_osm_info()
    return super(MyModelAdmin, self).change_view(request, object_id,

It's a relatively small difference, I'll admit, but since the docs are probably most frequently read by those new to Django and possibly even Python itself, I believe the sample code should take into account eventualities such as the ModelAdmin being subclassed.
