Hello,
I have a model
class Post(models.Model):
...
authors = models.ManyToManyField('accounts.User', through='PostAuthor',
related_name='authors_posts')
class PostAuthor(models.Model):
user = models.ForeignKey('accounts.User')
post = models.ForeignKey(Post)
...
How can I use the Django 1.7 Prefetch object to load PostAuthors, this
does not work:
Post.objects.prefetch_related(
Prefetch(
'authors',
queryset=PostAuthors.object.select_related('user')
)
I got an exception:
django.core.exceptions.FieldError: Cannot resolve keyword 'authors_posts' into
field. Choices are: created, id, post, post_id,
user, user_id
Thanks for help,
Marcin Szamotulski
