In my project I use many tables such as table transaction_2021, transaction_2022, transaction_2023, and the same table will be created every time the year changes. Can this case be solved with 1 model, because I have searched for my problem and couldn’t find it.
Why you need to create separate tables for each year, you can simply add created_at field and then can filter queryset data with respective to year instead of creating a new table for each year.
If you’re using PostgreSQL, it natively supports partitioned tables. That’s what we use for this purpose.
