Hey all, if I have a foreign key on a model (say Model B has a foreign
key to Model A) and I do something like this:
a = A.objects.get( pk = 1 )
b = B.objects.get( pk = 1 )
if b.a == a :
# Do something
Is that inefficient, since its doing a join to pull b.a? Should I be
comparing their ids? How do I get that from the b model? Something
like this:
if b.a_id == a.id :
# Do something
Not sure about the syntax. Thanks!
