Django Rest Framework视图集正在返回选定的记录,而不是列表视图中的所有记录

我有一个django应用程序。我的应用程序中有一部分无法正常工作。到目前为止,我正在使用django rest框架视图集。我想要的是两个基本上在同一个视图集中有两个不同的列表视图。1返回accountviewset中的所有帐户,另一个列表视图根据帐户模型中的用户foreignkey返回与用户关联的所有帐户。

下面的代码返回与特定人员关联的所有帐户,但我无法使用列表视图返回数据库中的所有帐户。

class AccountViewSet(viewsets.ModelViewSet):
    serializer_class = AccountSerializer
    queryset = Account.objects.all()
    lookup_field = 'user__username'

    def list(self, request):
        queryset = Account.objects.all()
        serializer_class = AccountSerializer

        def get_object(self):
            return self.queryset.get(user__username=self.kwargs.get('username'))

class AccountViewSet(viewsets.ModelViewSet):
    queryset = Account.objects.all();
    serializer_class = AccountSerializer
    filter_backends = (filters.DjangoFilterBackend,)
    filterset_fields = ('user', 'name', '_class')
    lookup_field = 'user__username'

    # def get_queryset(self):
    #     return self.queryset.filter(user__username=self.kwargs.get('username'))

当有一个帐户与一个用户关联时,它工作。 无法处理2个以上的帐户,错误为:

MultipleObjectsReturned at /api/users/accounts/omarjandali/
get() returned more than one Account -- it returned 2!

其他尝试不会返回端点中有特定用户或没有用户的任何帐户。

最大的问题是,它返回的是用户id,而不是用户用户名。

当前代码:

serializers.py:

class UserSerializer(serializers.ModelSerializer):
    class Meta:
        model = User
        fields = ('username', 'first_name', 'last_name', 'email', 'is_staff')

class ProfileSerializer(serializers.ModelSerializer):
    class Meta:
        model = Profile
        fields = ('user', 'gender', 'phone', 'ip_address', 'dob_month', 'dob_day',
                  'dob_year', 'address_street', 'address_city', 'address_state',
                  'address_postal', 'address_country', 'profile_pic', 'role')

class FriendSerializer(serializers.ModelSerializer):
    class Meta:
        model = Friend
        fields = ('requested', 'friended', 'status', 'blocked')

class AccountSerializer(serializers.ModelSerializer):
    user = UserSerializer(
        read_only = True,
    )

    class Meta:
        model = Account
        fields = ('user', '_id', 'name', 'balance', 'currency', 'bank_name',
                  'routing', '_class', 'type', 'active', 'main', 'synapse')

Views.py:

class UserViewSet(viewsets.ModelViewSet):
    serializer_class = UserSerializer
    queryset = User.objects.all()
    lookup_field = 'username'

class ProfileViewSet(viewsets.ModelViewSet):
    serializer_class = ProfileSerializer
    queryset = Profile.objects.all()
    lookup_field = 'user__username'

class FriendViewSet(viewsets.ModelViewSet):
    serializer_class = FriendSerializer
    querset = Friend.objects.all()
    lookup_field = 'user__username'

class AccountViewSet(viewsets.ModelViewSet):
    queryset = Account.objects.all();
    serializer_class = AccountSerializer
    filter_backends = (filters.DjangoFilterBackend,)
    filter_fields = ('user',)
