使用Django模板系统返回JSON响应 [英] Return JSON response using Django template system

问题描述

有可能吗? 我试过了:

Is it possible? I tried:

def jsonview(request):
  context = {}
  context['date'] = datetime.now()
  return render(request, "json.html", context, content_type="application/json")

json.html文件:

The json.html file:

{% load i18n %}

'{"date": "{{ date|escapejs }}", "test": "hello"}' 

响应为:

'\n\n{"date": "2014\u002D11\u002D13 11:58:31.635102", "test": "hello"}' 

所以错误是:

SyntaxError: JSON.parse: unexpected character at line 3 column 1 of the JSON data

推荐答案

简单的方法是首先将模板中的数据呈现为字符串，然后像下面的示例代码一样将其作为json进行响应.

simple approach is to render first the data from your template to string and response it as json like the sample code below.

from django.template.loader import render_to_string
from django.http import HttpResponse
def jsonview(request):
      context = {}
      context['data'] = render_to_string("json.html", {'date': datetime.now()})
      return HttpResponse(json.dumps(context), content_type="application/json")
