Following is my model: class Story(models.Model): author = models.ForeignKey(User, related_name=’author_id’, default=1) source = models.ForeignKey(User,

  • 0

Following is my model:

class Story(models.Model):
    author = models.ForeignKey(User, related_name='author_id', default=1)
    source = models.ForeignKey(User, related_name='source_id', default=2)

User is the django provided model.

Now I need to find out number of articles authored and sourced by each user.

I thought of using story_set with user object:

res = User.objects.annotate(Count('story_set'))

However, there are two columns in story referencing User. Hence, Django won’t know which one to use?

Can anyone help me on this?

    story_set doesn’t exist one way or another. That would’ve been the default related_name if you hadn’t provided one. Since you did, you have to use those.

    res = User.objects.annotate(Count('author_id'))

    OR

    res = User.objects.annotate(Count('source_id'))

    So, that’s how Django knows the difference.

    FYI: if you had used the default (so you accessed stories via .story_set.all(), you don’t use the “_set” part in queries. It would just be Count('story').
