As long as D has a foreign Key FK relations with both B and C, it
should validate. What you will end up with is a ternary relation
between A, B, and C. Whether this is what you want is between you and
your requirements :-)

Bah, this is what I get for reading too quickly.  The answer is maybe,
you'd have to try it.  I see no obvious reason it wouldn't work
though.

class A defines an consumer order

class B and C both define different lines of product

I'd like to store all the ordering info in one intermediate table
while maintaining different tables for the porducts

I don't believe it would work, but even if it did, what would this do?
 What's the expecected behavior?

Intermediate Table question

[LeeRisq]

Does anyone know if an intermediate table can be specified on more
than two models? For instance:

class A(m.Model):
   B = ManyToManyField(B, through='D')
   C = ManyToManyField(C, through='D')

Will this validate and actually work?
