如何配置viewsets.ModelViewSet以使用在请求正文中传递的参数进行过滤 Django Rest Framework

如何解决如何配置viewsets.ModelViewSet以使用在请求正文中传递的参数进行过滤 Django Rest Framework

我正在使用DJANGO-REST-FRAMEWORK构建API。我正在尝试使用传递给请求主体的参数来过滤后端，这是我的设置：

views.py

from .models import UsstatesG
from .serializer import UsstatesSerializer
from rest_framework import viewsets
from rest_framework.response import Response
from rest_framework.decorators import action

class StatesViewSet(viewsets.ModelViewSet):

    queryset = UsstatesG.objects.all()
    serializer_class = UsstatesSerializer

    @action(detail=False)
    def get_by_id(self,request):
        body = request.body.decode('utf-8')
        body = json.loads(body)

        state_list = UsstatesG.objects.filter(st_abbr__in=body['id'])
        serializer = self.get_serializer(state_list,many=True)
        return Response(serializer.data)

models.py

class UsstatesG(models.Model):
    st_fips = models.CharField(primary_key=True,max_length=2,unique=True)
    geom = models.MultipolygonField(blank=False,null=False)
    objectid = models.BigIntegerField(blank=False,null=False)
    st_name = models.CharField(max_length=50,blank=False,null=False)
    st_abbr = models.CharField(max_length=2,null=False,unique=True)

    class Meta:
        managed = False
        db_table = 'US_States_G'

urls.py

from django.contrib import admin
from django.urls import include,path,re_path
from api import views
from rest_framework.routers import DefaultRouter

router = DefaultRouter()
router.register(r'states',views.StatesViewSet)
router.register(r'states/q',views.StatesViewSet.get_by_id,basename='UsstatesG')

urlpatterns = [
    path('api/location/v1/',include(router.urls)),

serializer.py

from rest_framework_gis.serializers import GeoFeatureModelSerializer
from .models import UsstatesG

class UsstatesSerializer(GeoFeatureModelSerializer):
    class Meta:
        model = UsstatesG
        geo_field = "geom"
        fields = ('st_fips','st_name','st_abbr')
        read_only_fields = ('st_fips','st_abbr')

我想在请求的正文中传递参数（隐私问题） 即正文{“ id”：[“ TX”，“ CA”]}

我收到此错误：

 File "C:\GIT_WS\geospatial\api\REST\APIProject\urls.py",line 31,in <module>
    path('api/location/v1/',File "C:\ProgramData\Anaconda3\envs\cgeo\lib\site-packages\rest_framework\routers.py",line 78,in urls
    self._urls = self.get_urls()
  File "C:\ProgramData\Anaconda3\envs\cgeo\lib\site-packages\rest_framework\routers.py",line 339,in get_urls
    urls = super().get_urls()
  File "C:\ProgramData\Anaconda3\envs\cgeo\lib\site-packages\rest_framework\routers.py",line 237,in get_urls
    routes = self.get_routes(viewset)
  File "C:\ProgramData\Anaconda3\envs\cgeo\lib\site-packages\rest_framework\routers.py",line 153,in get_routes
    extra_actions = viewset.get_extra_actions()
AttributeError: 'function' object has no attribute 'get_extra_actions'

由于我是DRF的新手，所以

1-这是一个好方法吗？我在使用正确的视图类（视图集？）吗？

2-筛选出传递自请求主体的值的模型的最佳方法（推荐方法）是什么？

注意：我正在处理地理空间数据，即Postgresql-PostGIS后端。我也在使用rest_framework_gis

示例代码，尤其是urls.py和views.py

的推荐代码

谢谢！

解决方法

在urls.py中，您配置了错误的内容：

router.register(r'states/q',views.StatesViewSet.get_by_id,basename='UsStatesG')

所需的视图已包含在该行中：

router.register(r'states',views.StatesViewSet)

默认情况下，端点为states/get_by_id/。如果要将端点设为states/q，请在@action装饰器中对其进行配置。

@action(detail=False,url_path='q')
