Dear All,

I'm new to the Django ORM, and quite new to ORMs in general.  I have two 
models (lets call them A and B) between which I have an interesting 
mapping.  There are precisely 2 B instances associated with each A 
instance.  Each A instance can have many B instances.  The order of Bs are 
important for As.

I want to do something like this:

class A(models.Model):
  b_1 = models.ForeignKey(B)
  b_2 = models.ForeignKey(B)

class B(models.Model):
  pass

Such that i can do:

>>> b1, b2, b3 = B(), B(), B()
>>> a1, a2 = A(b_1=b1, b_2=b2), A(b_1=b2, b_2=b3)
>>> b2.as
[<A ... >, <A ... >] #(order doesn't matter)

I expect I could eventually do something a bit hacky that would work, but 
what would be the best way to handle this?

Thanks in advance,

Richard
