Django REST API: How to respond to POST request? - django

Question

I want send POST request with axios(VueJS) and when Django server got a POST request then I want to get back that request message.
I tried make functions when got an POST request in Django server and then return JsonResponse({"response": "got post request"), safe=False)
JS function
sendMessage() {
axios({
method: "POST",
url: url,
data: this.message
})
.then(response => {
this.receive = response;
})
.catch(response => {
alert('Failed to POST.' + response);
})
}
}
views.py
from chat.serializer import chatSerializer
from chat.models import *
from rest_framework.routers import DefaultRouter
from rest_framework import viewsets
from django.http import JsonResponse
from django.views.generic import View
# Create your views here.
class get_post(View):
def post(self, request):
if request.method == 'POST':
JsonResponse({"response": 'got post request'}, safe=False)
but error says like that in django
Internal Server Error: /api/chat/
Traceback (most recent call last):
File "/usr/lib/python3/dist-packages/django/core/handlers/exception.py", line
47, in inner

in _get_response
self.check_response(response, callback)
File "/usr/lib/python3/dist-packages/django/core/handlers/base.py", line 309,

raise ValueError(
ValueError: The view chat.views.views.get_post didn't return an HttpResponse object. It returned None instead.

I think POST request is working properly, but Django code is something wrong.
Therefore, my question is..
How to fix and solve this error?
When I call axios in JS, inside '.then' we got a response so which data is come to this variable? Should I return this data like Response() or JsonResponse() method?

Answer 1

just add a return in the view ... like this:
class get_post(View):
def post(self, request):
if request.method == 'POST':
return JsonResponse({"response": 'got post request'}, safe=False)
because the error complains that the post function must return anything.
for the second question ya you need to return JsonResponse because you are dealing with APIs.
