Making changes to database structure in django
Hi I am looking to get some guidance on how to properly make changes to the models in django. Currently I'm working on an app where I have previously defined models and have uploaded data for these models. However I would like to make some changes to the schema of the database and edit and add/delete some columns of the tables. I am running into some issues with this where django will not allow me to make migrations or migrate after certain changes. If anyone could give me some tips on why this is happening and best practices to follow when I am making changes like this it would be very helpful. Also currently I am using a sqlite3 db.
I have tried to delete migrations and the database but had no success and I would also like a solution that is more practical if I wanted to make changes like this when the app in in production
