add-field

Asks for fields, as generate-model --fields, and inserts them in the Project, NewProject and UpdatableProject structs of project.rs, before the timestamps. The rest of the file is left as is, unlike generate-model --force. The sqlx derives, GraphQL and OpenAPI take the new fields from the structs.

Option	Description
--model	The model, Project
--migration	Create the ALTER TABLE ... ADD COLUMN migration
--foreign-keys, --unique	As for generate-model
--default	The SQL default of the new non-optional columns on the existing rows (--default "'none'"), asked for each of them otherwise
--sqlite, --postgres, --mysql	Required. The target database
--schema <name>	With --postgres, the schema of the table: the migration alters app.project
--output	The folder of the file

A non-optional column needs a default for the rows already in the table, enter ? instead to make the field optional. SQLite only adds a foreign key column when it is nullable, and only with a constant default (no CURRENT_TIMESTAMP).

$ octopux add-field --model Project --migration --sqlite
