在我的模型中，我有一个族表，用户可以在其中输入他们的族详细信息并存储他们的信息。但是如何基于当前用户ID获取/查询所有家庭成员

例如：userId=1添加了2个家庭成员，母亲和父亲。如何根据当前用户的用户ID查询得到这2个家庭成员

这是我的密码：

有人能帮我获取当前用户的家庭吗？假设我们有一个id为1的用户

usr = MyUser.objects.get(id=1) usr_famly = usr.family_set.values()

usr\u family
将拥有与id=1的
用户相关的所有家庭数据
假设我们有一个id=1的用户

usr = MyUser.objects.get(id=1) usr_famly = usr.family_set.values()

usr\u family
将拥有与id=1的
用户相关的所有家庭数据
您可以尝试以下方法：

class Family(models.Model): userId = models.ForeignKey(MyUser, related_name='user_family') relationship = models.CharField(max_length=100) first_name = models.CharField(max_length=50) last_name = models.CharField(max_length=50) gender = models.CharField(max_length=6, blank=True, null=True)

class FamilySerializer(serializers.ModelSerializer): class Meta: model = Family fields = ('id', 'first_name', 'last_name', 'gender', 'relationship') class MyUserSerializer(serializers.ModelSerializer): valid_time_formats = ['%H:%M', '%I:%M%p', '%I:%M %p'] birthTime = serializers.TimeField(format='%I:%M %p', input_formats=valid_time_formats, allow_null=True, required=False) my_family = FamilySerializer(many=True, source='user_family') class Meta: model = MyUser fields = ('userId', 'username', 'email', 'first_name', 'last_name', 'gender', 'nric', 'birthday', 'birthTime', 'my_family') read_only_fields = ('userId',) extra_kwargs = {"password": {"write_only": True}}

MyUserSerializer
现在将显示
userid
相关的家庭成员。如果要获取当前用户家庭成员，则需要覆盖
get\u queryset
方法
您的视图.py：

class MyUserViewSet(viewsets.ModelViewSet): serializer_class = MyUserSerializer get_queryset(self): return MyUser.objects.get(id=self.request.user.id)
现在，视图将返回当前用户族成员

很高兴提供帮助：）啊，对不起，我在查看页面时出错，因为没有重复检查。我有几个问题，在家族序列化程序中，我是否删除userId？在views.py
MyUserViewSet
中，我使用id而不是userId？对于
FamilySerializer
，您可以保留或删除
userId
，但我认为没有必要保留
userId
。在
MyUserViewSet
中，使用
userId
或
pk
而不是
id
。现在我遇到了这个错误
“MyUser”对象没有属性“myu family”。
我必须在MyUser模型中创建“myu family”字段吗？很抱歉给您带来这么多麻烦。如果您能给点时间学习DRF文档，那就更好了。你会从中学到很多。很高兴能帮上忙：）啊，对不起，我在查看页面时出错了，因为没有重复检查。我有几个问题，在家族序列化程序中，我是否删除userId？在views.py
