Rails Root directory path?

Question

I recently migrated my application across servers and set up my directories a little.

I ran into a problem where I had hard coded some paths, in particular, where I store all my attachments.

I moved my attachment directory in app_path/../attachments/*

Is there a variable that gets me my app_path, rails root directory, or whatever the correct term for it is?

And this variable needs to be accessible from controllers and models.

Thanks

Answer 1

Either: RAILS_ROOT or Rails.root

Answer 2

Hi, You can access rails app path using variable RAILS_ROOT.

For example, render :file => ”#{RAILS_ROOT}/public/layouts/mylayout.html.erb”

For super correctness, you should use:

Rails.root.join('foo','bar')

which will allow your app to work on platforms where / is not the directory separator, should anyone try and run it on one.
