Django Editing JsonResponse

Question

How I can add "points = " to this JsonResponse in Django?

My code look like this:

return JsonResponse(data=points, safe=False, json_dumps_params={'indent': 1})

Result :

[ { "x": 0, "y": 1 }, { "x": 0.315397047887207, "y": 0.694608645422627 } ]

what I want to do :

points=[ { "x": 0, "y": 1 }, { "x": 0.315397047887207, "y": 0.694608645422627 } ]

The return you want to have isn't a valid JSON. Do you really need a JSON response ? — Chiheb Nexus, Mar 14 '21 at 16:51

Look like you don't need JSON response. you need to pass a string in JSON.

for output like this : points=[ { "x": 0, "y": 1 }, { "x": 0.315397047887207, "y": 0.694608645422627 } ]

points_dict = {
    // value for points_key you can do some string concatenation for dynamic value
    'points_key': 'points=[ { "x": 0, "y": 1 }, { "x": 0.315397047887207, "y": 0.694608645422627 } ]'
}
return JsonResponse(data=points_dict, safe=False, json_dumps_params={'indent': 1})

Why would you return a string with JsonResponse rather than HttpResponse? — BoobyTrap, Mar 15 '21 at 13:39

As was mentioned before me, the response you want is not a JSON format. As was suggested by a different answer, you can convert it into a string and send it like that:

pointsstr = f'points=[{points_dict}]'
return HttpResponse(pointsstr)

If you want to still use a JSON format then I suggest doing the following:

return JsonResponse(data={'points': points}, safe=False, json_dumps_params={'indent': 1})

This way your response would be: {"points": [{ "x": 0, "y": 1 }, { "x": 0.315397047887207, "y": 0.694608645422627 }]}
