Question

我正在尝试构建一个前端，它将检查可用于显示不同UI元素的选项（如编辑按钮）。我可以从我的django rest框架后端中提取OPTIONS，但它显示的唯一操作是POST。

我正在使用带有DjangoObjectPermissions的ModelViewSet。

我收到此作为回复标题：

Access-Control-Allow-Headers:accept, accept-encoding, authorization, content-type, dnt, origin, user-agent, x-csrftoken, x-requested-with, access-control-allow-methods
Access-Control-Allow-Methods:DELETE, GET, OPTIONS, PATCH, POST, PUT
Access-Control-Allow-Origin:*
Access-Control-Max-Age:86400
Allow:GET, POST, HEAD, OPTIONS
Content-Length:405
Content-Type:application/json
Date:Wed, 02 Aug 2017 19:40:08 GMT
Server:WSGIServer/0.1 Python/2.7.12
Vary:Accept
X-Frame-Options:SAMEORIGIN

这是json发回的：

{  
   "name":"Project List",
   "description":"",
   "renders":[  
      "application/json",
      "text/html"
   ],
   "parses":[  
      "application/json",
      "multipart/form-data"
   ],
   "actions":{  
      "POST":{  
         "id":{  
            "type":"integer",
            "required":false,
            "read_only":true,
            "label":"ID"
         },
         "description":{  
            "type":"string",
            "required":true,
            "read_only":false,
            "label":"Description"
         },
         "name":{  
            "type":"string",
            "required":true,
            "read_only":false,
            "label":"Name",
            "max_length":80
         }
      }
   }
}

我试图从响应标题中读取允许的操作，但事实证明这是不可能的。有没有办法让Django Rest Framework显示用户的所有可用操作？

默认情况下DRF renders options only for POST and PUT methods。如果要将此行为扩展到更多HTTP方法，则需要创建tput rmcup的子类并覆盖SimpleMetadata方法。

Django Rest Framework OPTIONS操作仅显示POST
