Hi,
I have a model which requires two addresses: a mailing address and a
physical address. From an OO perspective it makes sense to have an Address
class and the Producer to have Address instances as properties, but I can't
seem to achieve this in django while still being able to edit the addresses
inline as part of the Producer admin.
I've tried this sort of thing:
class Address( models.Model ):
street = models.CharField( ... )
# city state zip, etc.
class Producer( models.Model ):
mailing_address = models.OneToOneField( Address, related_name='+' )
physical_address = models.OneToOneField( Address, related_name='+' )
but when I attempt to inline the addresses in the django admin I run into
trouble. I get errors like:
<class 'producers.models.Address'> has no ForeignKey to <class
'producers.models.Producer'>
(This error is true, of course. But I was under the apparently erroneous
impression that including related_name='+' would prevent django from
setting up the reverse relationship.)
I realize I could add a foreign key to Address to associate it with a
specific Producer but this feels backwards to me. An Address shouldn't need
to know whether it's for a Producer or some other object. It's just an
address.
I've been banging my head on this for far too long. Advice?
