I've got the following models defined:
class FeatureType(models.Model):
type = models.CharField(max_length=20)
def __unicode__(self):
return self.type
class Feature(models.Model):
value = models.CharField(max_length=200)
type = models.ForeignKey(FeatureType)
def __unicode__(self):
return u'type=' + repr(self.type.type) + u', value=' + repr
(self.value)
class Meta:
unique_together = ( ("value", "type"), )
This is what I tried for creating a new Feature:
ft = Feature(type=FeatureType(type='Color'), value='Red')
ft.type.save()
ft.save()
I get an IntegrityError at ft.save() saying that the type_id must not
be NULL. However, this works:
ft = Feature(type=FeatureType(type='Color'), value='Red')
ft.type.save()
ft.type = ft.type
ft.save()
Now, if I add in 'null=True' to the definition of 'type' in the
Feature model, then the first 3-line code set works, and correctly
gets the type_id defined.
Am I running into a bug, or am I misunderstanding something?
