如何通过过滤的网桥表字段排序查询集？

Question

Given the following models

class Blog(models.Model):
    followers = models.ManyToManyField(User, through='Follow')

class Follow(models.Model):
    blog = models.ForeignKey(Blog)
    user = models.ForeignKey(User)
    created = models.DateField(auto_now_add=True)

If I have a user, how can I get blogs the user follows, ordered by the date they started following them?

Answer 1

Try something like this:

qs = user.blog_set.all().order_by("follow__created")

For descending order use the following:

qs = user.blog_set.all().order_by("-follow__created")

I am not sure about "order_by" part, but you can "play" with it.
