Access a Many to Many model in Django.

access_m2m_model.py

from django.db import models

# Given the following classes:

class Foo(models.Model):
    name = models.TextField()

class Bar(models.Model):
    name = models.TextField()
    foos = models.ManyToManyField(Foo)

# Query the underlying many to many table directly.

def main():
    foos = Foo.objects.filter(name='foo')
    print(Bar.foos.through.objects.filter(foo__in=foos))
    # This works as well.
    print(Bar.foos.through.objects.filter(foo__name='foo'))
    # Just to make things clear.
    from django.db.models.base import ModelBase
    assert isinstance(Bar.foos.through, ModelBase)
