>>> from django.contrib.auth.models import User
>>> from music.models import Song
>>> user = User.objects.get(username='jdoe')
>>> song = Song.objects.get(pk=1)
>>> like = Like.objects.create(user, song)

or:

>>> like = Like.objects.create(user, 1, Song)

or:

>>> like = Like.objects.create(user, 1, "music.Song")

• Get the objects liked by a given user:

>>> from django.contrib.auth.models import User
>>> user = User.objects.get(username='jdoe')
>>> Like.objects.for_user(user)
>>> [<Like: Like object 1>, <Like: Like object 2>, <Like: Like object 3>]
