Django ForeignKey issue -

-

i have 2 classes

class a(models.model):     id=models.integerfield(primary_key=true)     name=models.charfield(max_length=200)     store_id=models.integerfield()     type=models.foreignkey(b)  class b(models.model):     id=models.integerfield(primary_key=true)     type=models.charfield(max_length=10)   class c(models.model):     id=models.integerfield(primary_key=true)     store=models.charfield(max_length=200)   class d(models.model):    id=models.integerfield(primary_key=true)    type=models.charfield(max_length=10)

in class a type foreignkey on b , store_id logical foreign key on c or d depending upon value of type.

in field set want show value of store depending upon typeafter calculations. type tells me table i.e c or d , vlaue of store tell me row in table c or d.now want show value on browser without overwriting values.is possible?

maybe should @ generic relations.
