You can't do this quite so directly. However, with a bit of poking about
under the covers you should be able to write your own version.
model1._meta.fields
will give you all the fields directly declared on model1 (except for
ManyToManyFields). You can run through that list looking for things that
are ForeignKey instances. For the reverse relations,
model1._meta.get_all_related_objects()
will return the list of models with relations (ForeignKey, OneToOne) to
the current model.A bit of playing around in the shell looking at dir()
of the returned objects should give you some clues as to how to proceed.
