Comment:
I think we really need more effort on your part in suggesting a solution
since the example is quite complex and very specialized. Once again, I
spent over an hour looking at this and couldn't figure out the exact
issue.
Something suspicious that seems related to the problem:
{{{
>>> a = BarInt.objects.get()
>>> a.pk
-15
>>> # a.pk is a shortcut for a.id_id
>>> a.id_id
-15
>>> a.id
<FooInt: 185>
>>> # how form data is generated
>>> model_to_dict(a)
{'id': -15}
>>> # how form choices are generated
>>> [str(a) for a in FooInt.objects.all()]
['185']
}}}
I could make the Id and Fk widgets work by adding this method to the
model:
{{{
def serializable_value(self, field_name):
val = super(FooInt, self).serializable_value(field_name)
if field_name == 'id':
return val.db_value
return val
}}}
but this may not be a good solution and I'm not sure if this will cause
other problems (also m2m didn't work).
Also it would be helpful to modify your project so that it doesn't use
`SubFieldBase` to verify the issue still exists without that (I suspect it
does).
