How is the :assets group in rails 3.1 handled by bundler?

Question

I don\'t understand what exactly is going on with this group, and what bundler is doing with it. Is it only loaded in dev mode? What if I want to make a new environment type

Answer 1

I think it should be,

if defined?(Bundler)
  # If you precompile assets before deploying to production, use this line
  Bundler.require(*Rails.groups(:assets => %w(development test)))
  # If you want your assets lazily compiled in production, use this line
  # Bundler.require(:default, :assets, Rails.env)
end

because there are some warning with the line,

Bundler.require *Rails.groups(:assets => %w(development test))

So we use,

Bundler.require(*Rails.groups(:assets => %w(development test)))

Hope this helps :)-
