Seems to be the other side of the relation. So, you need the foreign key
pointing to Category.id, from the above code it isn't obvious what that
field is. Maybe something like Category._meta.get_field('parent_id') is
correct?
This might allow both 1.5 and 1.6 to work:
if django's version is 1.6:
rel = ManyToOneRel(Category._meta.get_field('parent_id'), Category,
'id')
else:
rel = ManyToOneRel(Category, 'id')
