Django rest框架发送一个带单引号的字符串，而不是带双引号的JSON

I am sending JSON via POST to a view. The response I get back is only part JSON and the rest has changed from double quotes to single quotes.

我通过POST将JSON发送到视图。我得到的响应只是JSON的一部分，其余部分已经从双引号改为单引号。

My question is how to I make sure that I am sending all this back as JSON in a get? As an added bonus to my problem, I don't know what fields will be sent to leasee.

我的问题是，如何确保将所有这些作为get中的JSON发送回来?作为对我问题的额外奖励，我不知道什么字段将被发送给leasee。

The POST looks like:

这个职位看起来像:

{"leasee":
{"profession":{"permanentMakeup":true,"esthetician":true,"hairStylist":true},
"compare":{"uniqueVsChic":"56"},
"name":"dfasdfasdf",
"contact":{"text":true,"facebook":true}}}

But GET gives me:

但给我:

{"leasee":
"{'compare': {'uniqueVsChic': '56'}, 
'profession': {'hairStylist':True, 
'esthetician': True, 
'permanentMakeup': True}, 
'name':'dfasdfasdf', 
'contact':{'facebook': True,'text': True}}",
"created_at":"2015-05-22T23:27:13.598686Z",
"updated_at":"2015-05-22T23:27:13.609893Z"}

It appears that leasee = models.CharField(max_length=2000) is a charfield. So Django is simply returning the string stored in this field. Also it is not storing valid JSON string neither because JSON only allows double quote.

看起来leasee = models.CharField(max_length=2000)是一个charfield。Django只是返回存储在这个字段中的字符串。它也不存储有效的JSON字符串，因为JSON只允许双引号。

{'compare': {'uniqueVsChic': '56'}, 
'profession': {'hairStylist':True, 
'esthetician': True, 
'permanentMakeup': True}, 
'name':'dfasdfasdf', 
'contact':{'facebook': True,'text': True}}

looks like stringified dict. So you can try to parse leasee as a dict in your serializer.

看起来像字符串化的命令。所以你可以尝试把leasee解析为序列化器中的命令。
