Hi all,
I have a quick question about editing instances of child models in the
admin interface. I have a couple of models which derive from a (non-
abstract) parent model, thusly:
class Contact(models.Model):
first_name = models.CharField(...)
last_name = models.CharField(...)
# etc.
class LabMember(Contact):
hire_date = models.DateField(...)
# etc.
class Collaborator(Contact):
institution = models.CharField(...)
# etc.
I have another model with a ForeignKey field to Contact, because I
would like to be able to associate either LabMembers or Collaborators
with that field.
What I would l like to do is be able to add a Contact in the admin
interface (using the standard popup form) when creating an instance of
that model, and then later associate a new LabMember or Collaborator
instance with the previously-added Contact (either by changing the
Contact record, or by adding a new LabMember and having the option to
select an existing Contact).
I realize this may be a use case for an explicit OneToOne field
instead of inheritance, though I do like having the Contact fields
displayed inline when I add a new LabMember. So yes, I want to have
my cake and eat it too...but if I can only do one, suggestions for
this use case would be greatly appreciated!
Thanks,
Richard
