Hi all,
I have 4 classes and i want to build a get_absolute_url() for a class,
querying other 3 classes. But i get "list index out of range" error
for the FILTER row. Any ideas?
class Aaa( models.Model ):
...
...
class City( models.Model ):
...
...
class Bbb( models.Model ):
aaa = models.ForeignKey( Aaa )
city = models.ForeignKey( City )
...
...
class Ccc( models.Model ):
aaa = models.ForeignKey( Aaa )
...
...
def get_absolute_url(self):
bbbs = Bbb.objects.filter( aaa = self.aaa )
city = City.objects.get( id = bbbs[0].city.id )
return "/" + city.name + "/" + str(self.id)
