How to change a sqlite table column value type from Django model?
There is an easy way to do this. (in Django 2)
After making the necessary changes to the model.py file of your app, run command:

python manage.py makemigrations - This will generate a new file in migration folder of your app.
python manage.py migrate - This will apply those edits on actual databse.

To check if the changes have been applied, run command : .schema <tablename> in your terminal, after entering the sqlite command-line program.
I created a table before I code the Django app and now I merged both the app and the table with following command python manage.py inspectdb > models.py. However after some while I really need to change the value type of one of the column. Is it enough to chage it through the model file or do I need some additional steps?
