I'm trying to run django 1.9 on google app engine. Got the below error when trying to access API's through Google API Explorer.

I already added
builtins:

- django_wsgi: on
handlers:
- url: .*
script: mysite.wsgi.application
env_variables:
DJANGO_SETTINGS_MODULE: 'mysite.settings'
inside app.yaml file.
wsgi.py looks like
import os
from django.core.wsgi import get_wsgi_application
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")
application = get_wsgi_application()
I tried adding django.setup() line on the top of models.py but it shows a different error.

Temporary solution for this problem:
Seems like I need to open the home page first. So that it would loads the db since I made the homepage to return all the db table contents . Once the db lists shown on the home page, we are ready to call the Google API Explorer.
Is there any way to refine this solution?
You should first initiate django this way in your script:
import django
django.setup()
See https://docs.djangoproject.com/en/1.9/ref/applications/#django.setup
You can also look at the Troubleshooting section of the link to see other possibilities to solve this aprticular exception.
By adding the above two lines at the top of services.py file solves this problem for me..
In your script initiate django as:
from django_root_app.wsgi import application

further codes would b supplied based on request. Kindly help with it
The Could not parse version info string error is the issue in ticket 28441, which has been fixed in Django 1.11.5.
Note that it's always a good idea to use the latest point release (currently 1.11.5 for 1.11.X) to make sure you've got the latest security patches and bug fixes.
I'm using a project called Django Dynamic Scraper to build a basic web scraper on top of Django. Everything works find in development but when setting up on my Digital Ocean VPS I run into issues.
I'm using Supervisor to keep three things running:
Scrapyd on 0.0.0.0:6800
Celery task scheduler
Celery worker
Whenever Celery passes a job to Scrapyd to scrape I get an error logged to the Scrapyd log:

On the final line of the stacktrace it seems to be having trouble importing my Django project settings into the scrapy project settings. My scrapy project is located inside one of my Django apps as recommended by Django Dynamic Scraper.
Here is my Scrapy settings file where it tries to import Django Settings (and succeeds in development):

import sys
sys.path.append('../../../IG_Tracker/')
os.environ['DJANGO_SETTINGS_MODULE'] = 'IG_Tracker.settings'

I get a 500 Server Error while uploading my app on GAE. It works perfectly fine locally with dev_appserver with SETTINGS_MODE='prod'.
Based on the logs, it cannot find MySQLdb on GAE. It does not make sense to me.
