Question

我正在尝试将分页添加到我的项目中，找不到任何明确的文档或教程。

我有一份办公室名单

模型 Office.py

?>

串行

class Office(Model):
    name = CharField(_("name"), default=None, max_length=255, null=True)
    email = EmailField(_("email"), default=None, max_length=255, null=True)
    description = TextField(_("description"), default=None, null=True)

views.py

class OfficeSerializer(ModelSerializer):
     id = IntegerField(read_only=True)
     name = CharField(read_only=True)
     email = URLField(read_only=True)
     description = CharField(read_only=True)

class Meta:
    model = Office
    fields = ("id", "name", "email", "description")

有关使用分页返回Office列表的任何帮助吗？

Answer 1

http://www.django-rest-framework.org/api-guide/pagination/

只有在您使用通用符号时才会自动执行分页视图或视图集。如果您正在使用常规APIView，则需要执行此操作自己调用分页API以确保返回分页响应。请参阅mixins.ListModelMixin和的源代码 generics.GenericAPIView类的一个例子。

https://github.com/tomchristie/django-rest-framework/blob/master/rest_framework/mixins.py#L35 https://github.com/tomchristie/django-rest-framework/blob/master/rest_framework/generics.py#L166

所以我会建议像：

@api_view(["GET"])
@permission_classes((AllowAny,))
def offices(request):
    pagination_class = api_settings.DEFAULT_PAGINATION_CLASS
    paginator = pagination_class()
    queryset = Office.objects.all()
    page = paginator.paginate_queryset(queryset, request)

    serializer = OfficeSerializer(page, many=True)

    return paginator.get_paginated_response(serializer.data)

http://www.django-rest-framework.org/api-guide/pagination/

GET https://api.example.org/accounts/?limit=100&offset=400

响应：

HTTP 200 OK
{
    "count": 1023
    "next": "https://api.example.org/accounts/?limit=100&offset=500",
    "previous": "https://api.example.org/accounts/?limit=100&offset=300",
    "results": [
       …
    ]
}

settings.py

的示例

REST_FRAMEWORK = {
    'PAGE_SIZE': 10,
    'EXCEPTION_HANDLER': 'rest_framework_json_api.exceptions.exception_handler',
    'DEFAULT_PAGINATION_CLASS':
        'rest_framework_json_api.pagination.PageNumberPagination',
    'DEFAULT_PARSER_CLASSES': (
        'rest_framework_json_api.parsers.JSONParser',
        'rest_framework.parsers.FormParser',
        'rest_framework.parsers.MultiPartParser'
    ),
    'DEFAULT_RENDERER_CLASSES': (
        'rest_framework_json_api.renderers.JSONRenderer',
        'rest_framework.renderers.BrowsableAPIRenderer',
    )
}

Django使用自定义API视图进行框架分页
