我的Django Rest-Framework API中有以下Django视图

from django_filters.rest_framework import DjangoFilterBackend, RangeFilter, FilterSet
from rest_framework.filters import OrderingFilter, SearchFilter

from rest_framework import generics
from api.serializers import UserSerializer
from django.contrib.auth.models import User
from rest_framework import permissions
from api.permissions import IsOwnerOrReadOnly

from MyGameDBWebsite.models import Game, GameDeveloper, GameGenre, GameConsole
from api.serializers import GameSerializer, DeveloperSerializer, GenreSerializer, ConsoleSerializer


class GameList(generics.ListCreateAPIView):
    permission_classes = (permissions.IsAuthenticatedOrReadOnly,)
    serializer_class = GameSerializer

    filter_backends = (DjangoFilterBackend, OrderingFilter, SearchFilter,)
    filter_fields = ('owner__username', 'id', 'game_title', 'game_developer_name', 'game_console',
                     'game_genre', 'game_release_year', 'game_price',)

    ordering_fields = ('owner__username', 'id', 'game_title', 'game_developer_name', 'game_console',
                       'game_genre', 'game_release_year', 'game_price',)

    search_fields = ('game_title', 'game_release_year', 'game_price',)

    queryset = Game.objects.all()

    def perform_create(self, serializer):
        serializer.save(owner=self.request.user)

我的输出URL如下：http://127.0.0.1:8000/api/?owner__username=&id=&game_title=&game_developer_name=&game_console=&game_genre=&game_release_year=&game_price=

我想创建一个价格范围，这样我就可以从URL调用API来获取价格范围内的结果

指定FilterSet对于更高级的过滤要求，您可以指定视图应该使用的FilterSet类。例如：

import django_filters
from myapp.models import Game
from myapp.serializers import GameSerializer
from rest_framework import generics


class GameListFilter(django_filters.FilterSet):
min_price = django_filters.NumberFilter(name="price", lookup_type='gte')
max_price = django_filters.NumberFilter(name="price", lookup_type='lte')
class Meta:
    model = Game
    fields = ['min_price', 'max_price']


class GameList(generics.ListAPIView):
queryset = Game.objects.all()
serializer_class = GameSerializer
filter_class = GameListFilter

这将允许您发出如下请求：

http://example.com/api/games?max_price=8.00
