Heroku seems to be stripping out the JSON from POST requests
I can run my code locally and it works just as I want, but when I run it in Heroku it returns NoneTypes for everything and seems like it has no data in the request. from django.shortcuts import render from rest_framework import generics from rest_framework.response import Response from rest_framework.reverse import reverse from rest_framework.decorators import api_view import psycopg2 @api_view(['GET', 'POST']) def testVert(request): user = request.data.get('username') password = request.data.get('password') response = { "user": user, "pass": password } return Response(data=response) #request.readline() The readline also works on my local computer, but not on Heroku. I'm wondering if maybe there are some Heroku settings or if I need to look for the data elsewhere after it goes through Heroku's stuff. Thanks for any help! -

How can I create a working production build for my django-rest site?
I've been running yarn build, but when I visit index.html I see not only <noscript>You need to enable JavaScript to run this app.</noscript>, but when I click a link on that page, I find that the pathing does not work. For example, when I click a link that would take me to a sign up page, I just get Your file was not found. The URLs are clearly different between the two pages, one being file:///C:/Users/icant/GitProjects/moodzaic/moodzaic_django/assets/bundles/index.html and the other just being file:///C:/signup.

Guys im fairly new to Django and I just started working on a personal project and decided that ill-use pycharm (i think its related to the error, or not). when I run python manage.py runserverI get the error posted below.

Nginx 502 Bad Gateway after a Site Update - How to Resolve?
I updated my site, which is on a DO droplet, restarted gunicorn and nginx, and now I'm getting a 502 bad gateway error. I ran sudo tail -30 /var/log/nginx/error.log and here is the output: 2019/12/02 22:01:32 [crit] 24429#24429: *1 connect() to unix:/home/jake/mysite-main/mysite.sock failed (2: No such file or directory) while connecting to upstream, client: 198.85.222.158, server: 165.22.38.243, request: "GET / HTTP/1.1", upstream: "http://unix:/home/jake/mysite-main/mysite.sock:/", host: "www.mysite.com" 2019/12/02 22:02:44 [crit] 24466#24466: *1 connect() to unix:/home/jake/mysite-main/mysite.sock failed (2: No such file or directory) while connecting to upstream, client: 198.85.222.158, server: 165.22.38.243, request: "GET / HTTP/1.1", upstream: "http://unix:/home/jake/mysite-main/mysite.sock:/", host: "www.mysite.com" What are the best next steps? Thanks for any advice, I've been Googling and still haven't found the solution. -
Django Auto generate 10 digit unique number
So i been trying to generate 10 digit unique random number in django model without making it my primary key. My model is Class Transaction(models.Model): Referrence_Number = models.Charfield(max_lenght = 10, blank=True, editable=False, unique=True) I know that Django has special feature inside it to generate random string that i came to know after reading documentation. from django.utils.crypto import get_random_string get_random_string(10).lower() But my problem is how can i incorporate this get_random_string function inside my django transaction model in my Transcation_number Instance. I m actually new to django and cant able to figure it that out.
