Automatic request parser decorator for JSON/XML format

Hi, I’ve worked with Django for several months and I haven’t see a quick way to parse a request’s body which can be in JSON o XML format. Until now I’ve had to do:

import json

def some_view(request):
    if request.content_type == 'application/json':
        data = json.loads(request.body)
        # Uses 'data' variable as we can't set parsed data to request.body
        # Uses request.POST[...], or request.GET[...], etc

In cases where It’s expected to have multiple formats (an application which uses JQuery will send the request in application/x-www-form-urlencoded format, modern apps will send in json, and so on) it would be very cool to have a Django’s decorator to parse automatically especified formats and HTTP methods and set it to the request’s body to work with request.POST/GET/etc as a QueryDict instance.

The usage would be something like this:

from django.http import parse_request

@parse_request(['json', 'xml'], ['POST', 'GET', 'PATCH'])
def some_view(request):
    field = request.POST['field']

What do you think about it? Would you like me to make a PR with this new decorator?

Thanks in advance and sorry about my English

Hi Genarito,

Your English is nothing to apologise for!

I’ve never worked on Django’s internals, but I do use Django Rest Framework a lot for working with JSON. It’s a sensation when it comes to JSON and serialising your models.

I believe it also can work well with XML

And let me apologise if you were already aware of DRF. Just thought I’d mention it in case you hadn’t had the pleasure to work with it.




Hi Conor! First of all, thank you for answering! Secondly, I’ve worked with DRF and It’s an excelent tool. I didn’t know the existence of JSONP, I’ll give a try!

Anyway I think that It would be nice to have a simpler solution, a Django’s decorator would be easier to use, avoiding import a new dependency to the project or set a middleware.
