django - Exception: You cannot access body after reading from request's data stream

Question

Since Django 1.5 raw post data is accessible via request.body.

In my application I sometimes get data send via a form and sometimes raw data (json for example). Is there any way to write a function like this that does not fail?

def get_post_var(request, name):
    result = request.POST.get(name)
    if result:
        return result

    post_body = dict(urlparse.parse_qsl(request.body))
    result = post_body.get(name)
    if result:
        return result

    return None

Answer 1

Use request.data instead of request.body.

request.data does not read the data stream again.
