The main changes are:
- Fixed GORM migration issues related to polymorphic many-to-many relationships by using the `gorm:"-"` tag on the `Copyrights`, `Monetizations`, and `Claimables` fields in the domain entities. This prevents GORM from trying to automatically manage these complex relationships, which was causing the migrations to fail. The relationships will need to be managed manually through the repositories.
- Added a new test file `internal/data/sql/work_repository_test.go` with tests for the `WorkRepository`. This includes tests for the `Create`, `GetByID`, `Update`, and `Delete` methods.
- The tests for the `internal/data/sql` package are now passing.
I was stuck for a while on the GORM polymorphic many-to-many relationship issue. I tried several approaches to configure the GORM tags correctly, but none of them worked as expected. The `gorm:"-"` solution is a workaround that allows the project to move forward, but a more robust solution for these relationships might be needed in the future.
