Django查询具有ManyToManyFields的对象

Question

Here's the situation:

class Party:
    # Hosts of the party
    hosts = ManyToManyField("User")

I have a user u . I want to make a query for all the parties he's hosting. How do I do that?

Party.objects.filter(hosts__in=[u])
Party.objects.filter(hosts__contains=u)

neither of those work.

Answer 1

这个怎么样

u.party_set.all()

Answer 2

你可以这样做u.party_set.all()其中party_set是党经理对象就像Party.objects所以你也可以把它应用不同的过滤器。您可以进一步挖掘的东西在这里
