How to add data to my sqlite3 database through a python script?
I also have added a custom management command that can be ran through the shell using manage.py. Let's call it script.py.
Now, my script.py runs a few functions and ends up with a couple of variables that I want to add to the database (sqlite3). I assume I have to add some function in script.py that should add the data, but I have no idea what commands to use for that.
Should I use the commands from the sqlite documentation or are there some kind of django commands that I can use?
Some of my models have objects (ForeignKey), so I am not sure if that would be the right approach.
I need a SQLite Sanity Check for my Python App
So far I have designed my script to handle the finance reports telling me whose direct debits have been successful or failed and a userform in excel that will collect when the team gives out any payments.

- A payment table with an autoincrement command to keep a unique ID
- A Direct Debit table, each row any dates a DD is due to be repaid to us for that clients loans. I decided to do this as I can report on how much we expect back in the future, but also I don't always know whether they will pay in one installment or several
- A table that has details about actual repayments. This could be via the dd method (will also log when these fail), but also any other repayment method they pay with.
