Overview

The headline command: model + migration + route + a reactive CRUD resource, the way rails g scaffold emits a plain one.

Subclasses Rails' ResourceGenerator, which is the model generator plus the resource_route hook — so the model, its migration, its fixtures and the route all come from Rails itself, unchanged. Only the controller half is ours.

Stock rails g scaffold is deliberately left alone: this lives under its own namespace and nothing here registers as Rails' scaffold_controller.

  # Raised HERE rather than in a task, because the inherited orm hook
  # runs first and would otherwise write a model and a migration before
  # the controller generator discovered it had nothing to work from.
  raise ::Rails::Generators::Error, <<~MESSAGE.strip
    #{self.class.banner} needs at least one field — the migration has not run when the
    views are generated, so the schema cannot be read yet. For a model that
    already exists, use:

        bin/rails g hibiki:rails:scaffold_controller #{name}
