django query select_related()

I got a question concerning select_related(). Assuming I do not specify the depth nor the attributes i.e items = ModelA.objects.selected_related(), does it work for reverse relationship i.e items[0].fk_set?

Also, if we pass items into context and use it inside the django templates, will accessing the foreign keys of items inside the template hit the database?

It doesn't work for reverse relationship, there will be additional database hit. You can easily check it yourself with debug_tolbar.

There is no difference where to evaluate queryset: in view or in template.
