Django rest框架在ViewSet中覆盖page_size [英] Django rest framework override page_size in ViewSet

问题描述

我有django休息框架分页的问题。
我已经在如下设置中设置了分页：

 'DEFAULT_PAGINATION_CLASS'：'rest_framework.pagination.PageNumberPagination'，
'PAGE_SIZE'：1 
  

以下是我的观点。

  class HobbyCategoryViewSet（viewsets.ModelViewSet）：
 serializer_class = HobbyCategorySerializer 
 queryset = UserHobbyCategory.objects.all （）
  

我想为此视图设置不同的页面大小。我已经尝试设置page_size和Paginate_by类变量，但列表是按照设置中定义的PAGE_SIZE分页的。任何想法我错了吗？

解决方案

我通过创建自定义分页课来修复这个问题。并在课堂上设置所需的pagesize。我在我的视图中使用了这个类作为pagination_class。

  class ExamplePagination（pagination.PageNumberPagination）：
 page_size = 2 
 
 class HobbyCategoryViewSet（viewsets.ModelViewSet）：
 serializer_class = HobbyCategorySerializer 
 queryset = UserHobbyCategory.objects.all（）
 pagination_class = ExamplePagination 
  

我不知道是否有更容易的方法。这一个为我工作。但是，我觉得创建新类只是为了更改page_size不好。

编辑 - 简单的解决方案设置为

ViewSet中的

  pagination.PageNumberPagination.page_size = 100 
  

  class HobbyCategoryViewSet（viewsets.ModelViewSet）：
 serializer_class = HobbyCategorySerializer 
 queryset = UserHobbyCategory.objects。 all（）
 pagination.PageNumberPagination.page_size = 100 
  

I am having problem with django rest framework pagination. I have set pagination in settings like -

'DEFAULT_PAGINATION_CLASS':'rest_framework.pagination.PageNumberPagination',
'PAGE_SIZE': 1

Below is my viewset.

class HobbyCategoryViewSet(viewsets.ModelViewSet):    
    serializer_class = HobbyCategorySerializer
    queryset = UserHobbyCategory.objects.all()

I want to set different page size for this viewset. I have tried setting page_size and Paginate_by class variables but list is paginated according to PAGE_SIZE defined in settings. Any idea where I am wrong ?

解决方案

I fixed this by creating custom pagination class. and setting desired pagesize in class. I have used this class as pagination_class in my viewset.

class ExamplePagination(pagination.PageNumberPagination):       
       page_size = 2

class HobbyCategoryViewSet(viewsets.ModelViewSet):    
    serializer_class = HobbyCategorySerializer
    queryset = UserHobbyCategory.objects.all()
    pagination_class=ExamplePagination

I am not sure if there is any easier way for this. this one worked for me. But I think its not good to create new class just to change page_size.

Edit - simple solution is set it like

pagination.PageNumberPagination.page_size = 100 

in ViewSet.

class HobbyCategoryViewSet(viewsets.ModelViewSet):    
    serializer_class = HobbyCategorySerializer
    queryset = UserHobbyCategory.objects.all()
    pagination.PageNumberPagination.page_size = 100
