# Monolith Model Development ## Use this skill when - Adding a new persisted domain entity. - Updating schema and model helpers. ## Default approach 1. Scaffold with `make generator model <Name> field:type...` when possible. 2. Confirm model is added to `db/db.go` AutoMigrate list. 3. Add/adjust helper functions in `app/models/<name>.go`. 4. Add tests under `app/models/*_test.go` and run `go test ./...`. ## Expected model conventions - Embed `gorm.Model`. - Include `IsActive bool` soft-delete style flag. - Provide CRUD helpers (`CreateX`, `GetXByID`, `GetAllXs`, `UpdateX`, `DeleteX`). - Keep validation in hooks (`BeforeSave`/`AfterSave`) or explicit helper functions. ## If you need full REST scaffolding Use `make generator resource <singular> field:type...`. This will create model + controller + routes + views in one pass. ## Migration notes - Auto migration occurs during `db.InitDB()` on startup. - Adding a model without registering it in AutoMigrate means no schema creation.
