如何獲取查詢集的外鍵對象？

Question

我有三個型號項目，會員，用戶

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

class User 
    #...user model... 

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

如果我想獲得一個項目（P）的所有用戶對象，我可以做p.members。但是，我怎樣才能輕鬆獲得項目的所有管理員（用戶對象）？

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)
