Description
The last part of this fails (with MySql 5):
from django.db import models class Category(models.Model): name=models.CharField(maxlength=40) class Thing(models.Model): """ >>> cat1 = Category.objects.create(name="cat2") >>> cat1.save() >>> cat2 = Category.objects.create(name="cat2") >>> cat2.save() >>> my_thing = Thing.objects.create(name="My thing") >>> my_thing.save() >>> my_thing.categories = [cat1, cat2] >>> Thing.objects.filter(categories=cat1) [<Thing: My thing>] >>> Thing.objects.filter(categories=cat2) [<Thing: My thing>] >>> Thing.objects.filter(categories=cat1).filter(categories=cat2) [<Thing: My thing>] """ name=models.CharField(maxlength=40) categories = models.ManyToManyField(Category) def __str__(self): return self.name
Am I right in thinking that ought to pass?

(In [7477]) Merged the queryset-refactor branch into trunk.
This is a big internal change, but mostly backwards compatible with existing
code. Also adds a couple of new features.

This is a dupe of something (I thought), but I can't find. It should work. I'm working on it.
