I am trying to use ForeignKey data returned from a page and view, and
am having trouble. I am missing something fundamental I think.
Say I have 2 models
class TopModel(models.Model):
name = models.CharField(max_length=50)
db_type = models.CharField(max_length=1, choices=STATUS_DBS)
# and another class with an FK to the above
class OtherModel(models.Model):
name = models.CharField(max_length=50)
topmodel = models.ForeignKey(TopModel)
# Form classes for the above are just as follows:
class TopModelForm(forms.ModelForm):
class Meta:
model = TopModel
class OtherModel(forms.ModelForm):
class Meta:
model = OtherModel
Anyway, if I go to a page template and view for OtherModel, say the
user selects an fk for TopModel in OtherModel,
I want to get back the actual fk number , e.g, 3, 10, 1, or whatever
from the post dict. I currently do not get a value back for this (or
I am calling it the wrong thing or something).
I just want the Interger id for the fk that would be in the db). I
want to use this type of access several layers deep in cases,
and this seems like it should be dirt simple (it would be the old
school way), but of course, I am trying to get away from that.
I have been looking through the docs and things and just confusing
myself
more and more.
So, can anyone tell me what I am doing wrong or if there is an easy
(and efficient) way to do this, or perhaps point me to a piece of
actual code that does something similar.
Thanks very much,
Peter
