Django: Performing ManytoMany Queries

May 27th, 2009 posted by Bender Rodríguez

Given the models below:

class Artist(models.Model):
name = models.CharField(max_length=128)

def __unicode__(self):
return u'%s' %(self.name)

class Album(models.Model):
title = models.CharField(max_length=128)
artists = models.ManyToManyField(Artist)

def __unicode__(self):
return u'%s' %(self.title)

class Song(models.Model):
title = models.CharField(max_length=128)
albums = models.ManyToManyField(Album)

def __unicode__(self):
return self.title

Here is how you can get a list of all the songs a particular artist has:

Song.objects.filter(albums__artists=)
