Comment (by r1cky):
The reason I needed related_name is that, in my case (1), the
GenericRelation is actually in an abstract base class and we inherit from
it into two models with the same name in separate apps. If I don't set it,
I get an error about collisions during model validation when starting the
dev server:
{{{
forums.thread: Accessor for m2m field 'watches' clashes with related m2m
field 'Watch.thread_set'. Add a related_name argument to the definition
for 'watches'.
kbforums.thread: Accessor for m2m field 'watches' clashes with related m2m
field 'Watch.thread_set'. Add a related_name argument to the definition
for 'watches'.
}}}
We have a model named Thread in two different apps. I guess that is a
different bug? The validation of models probably shouldn't complain in
this case.
