Question

I created a scaffolding gem that uses another gem to generate presenters. I created this scaffolding generator using the Rails 3 generators. It works like this:

rails g stager:scaffold User

I created another gem to generate presenters. I want to use this gem to generate a presenter with each scaffold. Currently I’m doing the following to accomplish this:

run "rails g exhibit:presenter #{scaffold_name}"

The problem is that it seems to reload the Rails environment when this generator is called, making it a bit slow. I’m wondering if there’s a better way to call another generator within a generator. So: is there a better way to create a Rails generator inception? 😉

Answer 1

You must define a hook_for the other generator in your generator class. The ScaffoldGenerator is probably the best example of this, as it has a hook for the scaffold_controller generator.

If you want to pass in arguments to your generator, it’s probably better to use something like the hook_for examples further down in this file for assets and stylesheet engine.
