As I look inside the code, the field `b_id` is set only when `a.b` is being set. So, the workaround is: {{{ a = A(name=""Test A"") a.b = B(name=""Test B"") a.b.save() a.b = a.b # workaround a.save() a = A.objects.get(id=a.id) assert a.b is not None }}} Now it works as expected. Is it a bug or a feature? I can't find anything in the docs. If it is a bug, I guess the object should have a list of which objects are pointing to it. So, when it is added, it should updated everyone id field." Bug closed Database layer (models, ORM) 1.5 Normal duplicate msbrogli@… Unreviewed 0 0 0 0 0 0
