Using better_errors on Ubuntu with SublimeText 2

After I installed the fantastic better_errors gem, I was disappointed to notice that linking to your text editor doesn't work correctly on Ubuntu (at least, it didn't for me). Here's how I fixed it.

First, create a new desktop entry:

# /usr/share/applications/subl-urlhandler.desktop

# autoload concerns
module YourApp
  class Application < Rails::Application
    config.autoload_paths += %W(
      #{config.root}/app/controllers/concerns
      #{config.root}/app/models/concerns
    )
  end
end

class PostsController < ActionController::Base
  def create
    Post.create(post_params)
  end
  
  def update
    Post.find(params[:id]).update_attributes!(post_params)
  end
