无法筛选，排序和搜索数据的嵌套端点API

Question

我的API端点是http://127.0.0.1:7009/apps/2/versions

我无法过滤，订购和搜索特定版本数据

models.py：

class App(models.Model):
    app_id = models.CharField(max_length=40,help_text="app_id of the app",unique=True)
    name=models.CharField(max_length=40,help_text="name of the app")

class AppVersion(models.Model):
     app_version = models.CharField(max_length=200)
     app_description = models.CharField(max_length=200,blank=True)

Views.py：

from django_filters.rest_framework import DjangoFilterBackend
from rest_framework.filters import OrderingFilter,SearchFilter
class AppVersionListView(mixins.ListModelMixin,mixins.CreateModelMixin,generics.GenericAPIView):

    lookup_field = 'pk'
    serializer_class = appVersionsSerializer
    queryset = AppVersion.objects.all()
    filter_backends = (DjangoFilterBackend, OrderingFilter,SearchFilter,)
    filter_fields = ('id','app_version','app_description ')
    ordering_fields = '__all__'
    search_fields =('app_version','app_description')

serializers.py：（app_versions的类）

class appVersionsSerializer(QueryFieldsMixin,serializers.ModelSerializer):
     class Meta:
        model = AppVersion
        fields = ('apps','app_version','app_description')

我想基于“ app_description”来过滤版本数据，

获取： http://127.0.0.1:7009/apps/2/versions?app_description = FileCommander

预期输出：

应过滤数据并返回具有该说明的结果

[
{
        "apps": 2,
        "app_version": "v1",
        "app_description ":"FileCommander"
}]

实际输出：

[
{
        "apps": 2,
        "app_version": "v1",
        "app_description ":"FileCommander"
},
{
        "apps": 2,
        "app_version": "v2",
        "app_description ":"cooking"
}]

如何搜索，过滤或订购版本数据？
