Rails Ruby on Rails

One of my common tweaks to the Rails file structure is to move my mailers into app/mailers, and their views into app/mailers/views. This is no longer easily possible in environment.rb or an initializer, because railties/lib/initializer.rb calls 'load_view_paths' after the environment, application initializers, and after_initialize blocks are run. That method forcibly assigns ActionViews' path to ActionMailer.

This is reproducible by setting config.action_mailer.template_root in any of the above parts of the startup process, and then checking it's value in script/console.

I've fixed this in my own application simply by changing the assignment to be ||= rather than =, but I'm sure this is not a proper fix, and the view path cache code is a bit beyond me.
