[Fixed]-Django Rest Framework: empty request.data

✅

You need to send the payload as a serialized json object.

import json
import requests
payload = {"foo":"bar"}
headers = {'Content-type': 'application/json'}
r = requests.put("https://.../myPk/", data=json.dumps(payload), headers=headers)

Otherwise what happens is that DRF will actually complain about:

*** ParseError: JSON parse error - No JSON object could be decoded

You would see that error message by debugging the view (e.g. with pdb or ipdb) or printing the variable like this:

def update(self, request, pk = None):
    print pk
    print str(request.data)

Check 2 issues here:-

  1. Json format is proper or not.
  2. Url is correct or not(I was missing trailing backslash in my url because of which I was facing the issue)

Hope it helps

Assuming you’re on a new enough version of requests you need to do:

import requests

payload = {"foo":"bar"}
r = requests.put("https://.../myPk", json=payload, headers=headers)

Then it will properly format the payload for you and provide the appropriate headers. Otherwise, you’re sending application/x-www-urlformencoded data which DRF will not parse correctly since you tell it that you’re sending JSON.
