Models in Amber V2

Amber CLI 2.0.6 installs Grant and the selected database driver in the supported web template. SQLite is the zero-setup default; PostgreSQL and MySQL are selected with amber new APP -d pg or -d mysql.

Grant is the supported V2 model layer. The generated shard.yml pins the reviewed Grant commit, config/database.cr registers the primary connection, and amber database applies Micrate migrations under db/migrations/.

Generate the first complete model and resource from the application root:

Run from: the application root beside shard.yml.

Terminal
amber generate scaffold Pet name:string:required species:string:required adopted:bool
amber database migrate

If you are migrating an Amber 1 application, keep the 1.4.1 documentation open for the existing Granite or Jennifer code and use the Granite-to-Grant guide only after reviewing its compatibility notice and proving a database restore.
