如何获取查询集的外键对象？

Question

我有三个型号项目，会员，用户

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

class User 
    #...user model... 

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

如果我想获得一个项目（P）的所有用户对象，我可以做p.members。但是，我怎样才能轻松获得项目的所有管理员（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)
