HI all.
I write a model:
class UserGroup(models.Model):
groups = models.ForeignKey(Group, to_field='id')
and when I into admin backend:
<https://lh4.googleusercontent.com/-dxgts8I14Sw/UDXNrsM0CZI/AAAAAAAAAoA/6DQxSeD2mOw/s1600/123.jpeg>
According to the Django document the combobox item should be a "id"
field in Group model,
but it is not, why ?
Where from the documenttion you got impression of that? As documentation
states:
"Foreginkey.to_field
The field on the related object that the relation is to. By default,
Django uses the primary key of the related object"
There is nothing about representation in a select field on a form. It
still uses ID as a value to post. But what you see is just a
representation of the __unicode__ method. There is way to change that
behaviour for a particular form field if needed.
