python - Django Rest Framework - URL 查询不起作用？

问题描述

我正在用 Django 编写一个使用 Django Rest 框架的应用程序。对 API URL 的 GET 请求有效，但是当我向它添加查询时，例如 '?id=1845' 它实际上并没有执行查询，它仍然返回完整的结果列表。

在下面的代码中，我试图查询“指标列表”

视图.py

from django.shortcuts import render
from django.http import JsonResponse

from rest_framework.decorators import api_view
from rest_framework.response import Response
from .serializers import IndicatorSerializer

from data_platform.models import Indicator

@api_view(['GET'])
def apiOverview(request):
    api_urls = {
        'Indicator List':'/indicator-list/',
        'Indicator Detail':'/indicator-detail/<str:pk>/',
    }
    return Response(api_urls)

@api_view(['GET'])
def indicatorList(request):
    indicators = Indicator.objects.all()
    serializer = IndicatorSerializer(indicators, many=True)
    #filterset_fields = ('id')
    #filter_backends = [DjangoFilterBackend]
    return Response(serializer.data)

@api_view(['GET'])
def indicatorDetail(request, pk):
    indicators = Indicator.objects.get(id=pk)
    serializer = IndicatorSerializer(indicators, many=False)
    return Response(serializer.data)

网址.py

from django.urls import include, path
from . import views

urlpatterns = [
    path('', views.apiOverview, name="api-overview"),
    path('indicator-list/', views.indicatorList, name="indicator-list"),
    path('indicator-detail/<str:pk>/', views.indicatorDetail, name="indicator-detail"),
]

序列化程序.py

from rest_framework import serializers
from data_platform.models import Indicator

class IndicatorSerializer(serializers.ModelSerializer):
    class Meta:
        model = Indicator
        fields = '__all__'

解决方案

我想到了！我不得不使用类视图而不是函数视图

class indicatorList(generics.ListAPIView):
queryset = Indicator.objects.all()   
serializer_class = IndicatorSerializer
filter_backends = [django_filters.rest_framework.DjangoFilterBackend]
filter_fields = ('id',)

并将“django_filters”添加到 INSTALLED_APPS
