#20234 closed Bug (fixed)

SingleObjectMixin does not add 'object' key to context

The documentation at says that 'object' will be in the context, as well as potentially context_object_name if given. However, actually only context_object_name is set in the context by this mixin; only if object is passed to the mixin (which BaseDetailView does) will it be included.

The MultipleObjectMixin does include 'object_list' in its get_context_data (though assumes it must be passed in rather than on the object, I'll file that as another ticket), so I assume this is an issue with SingleObjectMixin, and that it should set 'object' on context whether it is passed in as a kwarg or not.

I have a patch on a branch of my github fork:

If this ticket is applied, then I think get_context_data of ModelFormMixin becomes entirely superfluous - see ticket #20236.

Hmm, all "object" stuff does not seem to be very consistent (like you mention in your other tickets).

It also strikes me as strange, that these mixins rely on self.object being set, while it is only set in it's derived classes (that is probably why object was passed as a kwarg earlier).

I think the documented functionality is the correct functionality and this and #20236 can be fairly easily tidied up together.
