Django ORM: Selecting related set

Question

Say I have 2 models:

class Poll(models.Model):
    category = models.CharField(u\"Category\", max_length = 64)
    [...]

class Choice(models.Model):
    pol         


        

Answer 1

I think what you are trying to do is the term "eager loading" of child data - meaning you are loading the child list (choice_set) for each Poll, but all in the first query to the DB, so that you don't have to make a bunch of queries later on.

If this is correct, then what you are looking for is 'select_related' - see https://docs.djangoproject.com/en/dev/ref/models/querysets/#select-related

I noticed you tried 'select_related' but it didn't work. Can you try doing the 'select_related' and then the filter. That might fix it.

UPDATE: This doesn't work, see comments below.
