Django REST框架后置数组对象 [英] Django REST framework post array of objects

问题描述

我正在使用 Django REST框架，将API和Angular SPA与Restangular进行通信API。有时我必须添加多个对象来添加，我认为我可以将它们一起发送到数组中并发出一个请求。

当我尝试从错误的输入错误。如果我尝试从REST框架Web界面添加一个对象，我传递对象或数组的对象：

  //这个{text：gdhg，}，{text：gdhg，}，{text：gdhg，} 
 //或这个[{text：gdhg ，}，{text：gdhg，}，{text：gdhg，}] 
  

但是我收到ParseError。我错了什么，我必须改变什么或如何正确执行。

解决方案

我不知道问题是否仍然存在。但是，fiver提出的解决方案对我来说没有效果。
对我来说有用的是只覆盖 get_serializer 方法。

  def get_serializer（self，instance = None，data = None，
 files = None，many = True，partial = False）：
 return super（ViewName，self） .get_serializer（实例，数据，文件，
许多，部分）
  

如果你会注意到我在 get_serializer 的参数中设置默认的 many = True 。
除此之外，没有必要。另外如果您在视图中定义了pre_save和post_save方法，那么希望将列表（iterable）作为参数（就像你所说的那样），这个方法也是不需要的。

正在发布列表）方法不仅仅是一个对象。

  def post_save（self，objects ，* args，** kwargs）：

在post_save中，obj列表已创建

对象中的obj：
 do_something_with（obj）
  

I am using Django REST framework for API and Angular SPA with Restangular for comunication with the API. Sometimes I have to add more than one objects for adding and I think that I can send them together in array and make one request.

When I try to do this from the Restangular I recive error for Wrong input. If I try to add more then one object from the REST framework web interface I am passing objects or array of objects:

// this { "text": "gdhg", },{ "text": "gdhg", },{ "text": "gdhg", }
// or this [{ "text": "gdhg", },{ "text": "gdhg", },{ "text": "gdhg", }]

But I receive ParseError. Where I am wrong, what I have to change or how to do it properly.

解决方案

I am not sure if the problem still exist. But the solution suggested by fiver did not work for me. What works for me is overriding the get_serializer method ONLY.

def get_serializer(self, instance=None, data=None,
                    files=None, many=True, partial=False):
    return super(ViewName, self).get_serializer(instance, data, files,
                                                    many, partial)

If you will notice I am setting default many=True in arguments of get_serializer. Apart from that nothing is required. Overridng of create method is also not required.

Also if you are defining the pre_save and post_save method in the views, expects the list(iterable) as the argument(as you are posting the list) of method not just a single object.

def post_save(self, objects, *args, **kwargs):
    """
    In the post_save, list of obj has been created
    """
    for obj in objects:
        do_something_with(obj)
