Django的：测试后根据使用JSON对象的意见 [英] django: Testing POST-based views with json objects

问题描述

我有接受通过POST请求JSON对象几点看法Django应用程序。 JSON的对象是中等复杂与嵌套几层，所以我使用JSON库解析raw_post_data，如下所示：

I have a django application with several views that accept json objects via POST requests. The json objects are medium-complex with a few layers of nesting, so I'm using the json library to parse raw_post_data, as shown here:

def handle_ajax_call(request):
    post_json = json.loads(request.raw_post_data)

    ... (do stuff with json query)

接下来，我要编写测试这些意见。不幸的是，我无法弄清楚如何将JSON对象传递给客户。下面是我的code一个最简单的情况下版本：

Next, I want to write tests for these views. Unfortunately, I can't figure out how to pass the json object to the Client. Here's a simplest-case version of my code:

def test_ajax_call(self):
    c = Client()
    call_command('loadfixtures', 'temp-fixtures-1') #Custom command to populate the DB

    J = {
      some_info : {
        attr1 : "AAAA",
        attr2 : "BBBB",
        list_attr : [ "x", "y", "z" ]
      },
      more_info : { ... },
      info_list : [ 1, 22, 23, 24, 5, 26, 7 ]
    }

    J_string = json.dumps(J)
    response = c.post('/ajax/call/', data=J_string )

当我运行测试，它失败：

When I run the test, it fails with:

AttributeError: 'str' object has no attribute 'items'

如何传递JSON对象的Client.post方法？

How can I pass the JSON object in the Client.post method?

推荐答案

的 似乎暗示该文件，如果你传递一个 CONTENT_TYPE 参数 client.post ，它将把数据值作为一个文档并直接张贴。因此，尝试这样的：

The documentation seems to imply that if you pass a content_type parameter to client.post, it will treat the data value as a document and POST it directly. So try this:

response = c.post('/ajax/call/', content_type='application/json', data=J_string)
