Re: Upgrading django from 1.8 to 2.2.0

When you upgrade Django with pip, you can install the latest version of 1.9 with `pip install --upgrade "Django>=1.8,<1.10"` and then the same for each version, until you want the latest version of 2.2 and then use "Django>=1.8,<3.0". (actually the 1.8 is not needed here, you can also use 2.2 etc.)

Hi, 

Im upgrading my django project from 1.8 to 2.2.0. I have done the below changes.

1. Added on_delete to all the Foreign Key fields

2. Changed the url reverse import as from django.urls import reverse

3. Included path/re_path instead of url in all the app's url files.

4. Changed the MIDDLEWARE_CLASSES import in settings files to MIDDLEWARE = {}

I tried to run the server, still it says "TypeError: __init__() missing 1 required positional argument: 'on_delete' and it is pointing to /usr2/santhosh/myproject/myapp/migrations/0002_abc.py

What should I do now? Do I need to delete all the migration files and re-run python manage.py migrate or what?? Help me you are aware.

Regards,

Santhosh
