OneToOne mappings

[marcin....@gmail.com]

Hi.

The problem is:

A   1:1   B

B.a = OneToOne(A)

and there is a vA - an unmanaged model of A's view

A and B are linked together.

vA view is not linked with B, of course.

When I try to declare OneToOne within vA, Django expects vA.b_id field which is missing (that's ok).

When I try to declare sedond OneToOne within B (with db_column set to B.a_id and on_delete=DO_NOTHING),  Django complains about "models.E007": column name 'a_id that is used by another field.

When I declare second 1:1 and ignore models.E007, I can't save B model anymore due to "many assignments to the same column" (these values are same and will be always same, but "Django knows better").

So how to map a relation for my view? Is Django really so limited?
