Hey,
I had a problem recently that caused me some confusion!
I have a model that has a OneToOne field as the primary key. When
adding a new record in the admin form and entering a key that already
existed, I wasn't getting the expected "record already exists" error,
instead it was just overwriting the existing record!!
The problem was because I was implementing my own "clean" method on
the AdminForm. e.g.
class MyModelAdminForm(forms.ModelForm):
def clean(self):
....
return self.cleaned_data
as per the doco:
http://docs.djangoproject.com/en/1.0/ref/forms/validation/#cleaning-and-validating-fields-that-depend-on-each-other
But this then ignores the standard form validation that should still
occur. By adding a call to the super class clean method everything
became fine!
class MyModelAdminForm(forms.ModelForm):
def clean(self):
self.cleaned_data = super(MyModelAdminForm, self).clean()
....
return self.cleaned_data
Just be aware that any invalid data will be removed from cleaned_data
This is really a bug in the documentation I think... Can the doco be
updated??
Regards,
Simon
