Django的REST框架，爲list_route行動

Question

定製PAGE_SIZE我有一個list_route：

@list_route(methods=['get']) 
    def bought(self, request): 
     bought_photos = Photo.objects.filter(is_bought=True) 

     page = self.paginate_queryset(bought_photos) 
     if page is not None: 
      serializer = self.get_serializer(page, many=True) 
      return self.get_paginated_response(serializer.data) 
     serializer = self.get_serializer(bought_photos, many=True) 
     return Response(serializer.data) 

我如何可以設置自定義PAGE_SIZE只爲list_route，而不是它的ModelViewSet？

SOLUTION

1）創建CustomPagination類

from rest_framework.pagination import PageNumberPagination 

class CustomPagination(PageNumberPagination): 
    page_size = 10000 
    page_size_query_param = 'page_size' 

2）編輯list_route代碼：

@list_route(methods=['get']) 
    def bought(self, request): 
     bought_photos = Photo.objects.filter(is_bought=True) 
     paginator = CustomPagination() 

     page = paginator.paginate_queryset(bought_photos, request) 
     if page is not None: 
      serializer = self.get_serializer(page, many=True) 
      return paginator.get_paginated_response(serializer.data) 
     serializer = self.get_serializer(bought_photos, many=True) 
     return Response(serializer.data) 

Answer 1

我認爲下面的代碼應該足夠：

@list_route(methods=['get'], pagination_class=CustomPagination) 
def bought(self, request): 
    bought_photos = Photo.objects.filter(is_bought=True) 

    page = self.paginate_queryset(bought_photos) 
    if page is not None: 
     serializer = self.get_serializer(page, many=True) 
     return self.get_paginated_response(serializer.data) 
    serializer = self.get_serializer(bought_photos, many=True) 
    return Response(serializer.data)
