如何获取查询集的外键对象？

Question

我有三个模型Project，Member，User

class Project
    members = ManyToManyField(User, through="Member")

class User
    #...user model...

class Member
    project = ForeignKey(Project)
    user = ForeignKey(User)
    isAdmin = BooleanField(default=False)

如果我想获得项目的所有用户对象（p），我可以做p.members。但是，如何轻松获取项目的所有管理员（用户对象）？

Member.filter(project=p, isAdmin=True) # this gets all the admin member objects
# how to convert this to user objects?

Answer 1

User.objects.filter(member__isAdmin=True, member__project=p)
