如何删除重复的嵌套对象Django REST？

# serializers.py
from rest_framework import serializers
from .models import YourModel

class YourModelSerializer(serializers.ModelSerializer):
    class Meta:
        model = YourModel
        fields = '__all__'
        validators = []

# views.py
from rest_framework import generics
from .models import YourModel
from .serializers import YourModelSerializer

class YourModelListView(generics.ListCreateAPIView):
    queryset = YourModel.objects.all()
    serializer_class = YourModelSerializer

    def delete_duplicates(self):
        # 使用Django ORM的查询方法来筛选出重复的对象
        duplicates = YourModel.objects.filter(field_to_check_for_duplicates='some_value').values('field_to_check_for_duplicates').annotate(count=models.Count('id')).filter(count__gt=1)

        # 删除重复的对象
        for duplicate in duplicates:
            YourModel.objects.filter(field_to_check_for_duplicates=duplicate['field_to_check_for_duplicates']).delete()

    def delete(self, request, *args, **kwargs):
        self.delete_duplicates()
        return self.destroy(request, *args, **kwargs)

# urls.py
from django.urls import path
from .views import YourModelListView

urlpatterns = [
    path('your-models/', YourModelListView.as_view()),
]
