Favorite rvm flag

One of my favorite rvm flags is the —ruby-version flag. I use it when I want to create or use a gemset

rvm use 2.0.0@gemset_name --ruby-version

This creates the .ruby-version and .ruby-gemset dotfiles in your project directory so it will load the rvm ruby version and gemset automatically. Thanks for this rvm.

Customizing Rails generator templates

I find I spend a lot of time changing the scaffold code in controllers and views to wire up Devise authorization code and html layouts.

I wanted to tailoring the rails scaffold generator to automatically generate code in my controllers and views. I searched out the template files that rails uses to create the controller and view files.  These are located in the rvm railties gem directory.

/usr/local/rvm/gems/ruby-1.9.3-p374@<app_name>/gems/railties-3.2.9/lib/rails/generators/rails/scaffold_controller/templates/controller.rb /usr/local/rvm/gems/ruby-1.9.3-p374@<app_name>/gems/railties-3.2.9/lib/rails/generators/erb/scaffold/templates/index.erb.html (and the other views) /usr/local/rvm/gems/ruby-1.9.3-p374@<app_name>/gems/activerecord-3.2.9/lib/rails/generators/active_record/model/templates/model.rb /usr/local/rvm/gems/ruby-1.9.3-p374@<app_name>/gems/rspec-rails-2.12.0/lib/generators/rspec/controller/templates/controller_spec.rb

To tailor these, I created a local copy in the lib/templates directory and edited the app-specific copy. The local copy goes into each MVC specifc directory:

lib/templates/rails/scaffold_controller/controller.rb lib/templates/erb/scaffold/index.erb.html (and the other views) lib/templates/active_record/model/model.rb lib/templates/rspec/scaffold/controller_spec.rb

If you want to replace the scaffold_controller_generator code itself, you can create lib/generators/rails/my_scaffold_controller/my_scaffold_controller_generator.rb with templates under lib/generators/rails/my_scaffold_controller/templates directory.

Then I pointed my application to the new scaffold_controller in config/application.rb:

config.generators do |g| g.scaffold_controller = "my_scaffold_controller" end
