Question

基本上我正在学习如何通过我的rest api的url正则表达式来过滤结果的教程。我希望转到/ api / v1 / users / 1 /目标以获取与用户相关的目标列表。我已经搜索了django休息框架文档和大量的教程，但无法使其工作。我收到404错误，我要求的网址不存在。

myapp.views.py

class ListCreateUser(generics.ListCreateAPIView):
        queryset = User.objects.all()
        serializer_class = serializers.UserSerializer


class RetrieveUpdateDestroyUser(generics.RetrieveUpdateDestroyAPIView):
    queryset = User.objects.all()
    serializer_class = serializers.UserSerializer


class ListCreateGoal(generics.ListCreateAPIView):
    queryset = Goal.objects.all()
    serializer_class = serializers.GoalSerializer

    def get_queryset(self):
        return self.queryset.filter(user_id=self.kwargs.get('user_pk'))


class RetrieveUpdateDestroyGoal(generics.RetrieveUpdateDestroyAPIView):
    queryset = Goal.objects.all()
    serializer_class = serializers.GoalSerializer

urls.py

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^api/v1/users', include('dataStoreApp.urls', namespace='users')),

]

myapp.urls.py

urlpatterns = [
    url(r'^$',
        views.ListCreateUser.as_view(),
        name='user_list'),

    url(r'(?P<pk>\d+)/$',
        views.RetrieveUpdateDestroyUser.as_view(),
        name='user_detail'),

    url('r^(?P<user_pk>\d+)/goals/$',
        views.ListCreateGoal.as_view(),
        name='goals_list'),

    url('r^(?P<user_pk>\d+)/goal/(?P<pk>\d+)/$',
        views.RetrieveUpdateDestroyGoal.as_view(),
        name='user_goal_detail'),

]

myapp.serializers.py

class GoalSerializer(serializers.ModelSerializer):
    class Meta:
        model = Goal
        fields = ('id', 'user_id', 'name', 'amount',
                  'start_date', 'end_date', )


class UserSerializer(serializers.ModelSerializer):
    class Meta:
        model = User
        fields = ('username', 'email', 'id', 'password')
        read_only_fields = ('id', )
        extra_kwargs = {'password': {'write_only': True}}

myapp.models.py

class Goal(models.Model):
    class Meta:
    verbose_name_plural = 'Goals'
user_id = models.ForeignKey(settings.AUTH_USER_MODEL, default=1, 
on_delete=models.CASCADE)
NAME_CHOICES = (
    ("Goal 1", "Goal 1"),
    ("Goal 2", "Goal 2"),
    ("Goal 3", "Goal 3"),
)
name = models.CharField(max_length=100)
amount = models.DecimalField(decimal_places=2, max_digits=20)
start_date = models.DateField(default=None, blank=True, null=True)
end_date = models.DateField(default=None, blank=True, null=True)

def __str__(self):
        return self.name

使用django rest框架通用视图
