Rails_Root Require

RAILS_ROOT require?

Yes, you should require the environment.rb:

require File.dirname(__FILE__) + '/../config/environment.rb'
puts RAILS_ROOT

And Rails.root instead.

Rails.root in lib directory

RAILS_ROOT is deprecated, try Rails.root instead.

ruby-1.9.2-p180 :004 > File.expand_path(File.dirname(__FILE__) + '/config/environment.rb')
 => "/home/lpeabody/Documents/ccom_work/dataserver31/config/environment.rb" 
ruby-1.9.2-p180 :005 > require File.expand_path(File.dirname(__FILE__) + '/config/environment.rb')
 => true 
ruby-1.9.2-p180 :006 > Rails.root
 => #<Pathname:/home/lpeabody/Documents/ccom_work/dataserver31> 
ruby-1.9.2-p180 :007 > RAILS_ROOT
NameError: uninitialized constant RAILS_ROOT
    from (irb):7
    from /usr/local/rvm/rubies/ruby-1.9.2-p180/bin/irb:16:in `<main>'

Rails Root directory path?

In Rails 3 and newer:

Rails.root

which returns a Pathname object. If you want a string you have to add .to_s. If you want another path in your Rails app, you can use join like this:

Rails.root.join('app', 'assets', 'images', 'logo.png')

In Rails 2 you can use the RAILS_ROOT constant, which is a string.

Unable to locate where deprecated RAILS_ROOT is used

One of your gems is using RAILS_ROOT in its initialization code.

From your app's bundle directory, try: grep -R RAILS_ROOT .

(If you are using RVM, the bundle directory will be in ~/.rvm/gems; otherwise it may be .bundle within your app's main directory.)

Where does RAILS_ROOT (Rails.root) come from?

Change the symlink so that /var/www/application points to /home/user/application/public

Then just change RailsBaseURI to RackBaseURI and undo your changes to spawn_manager.rb

Previous discussion assumed single application.

    <Directory /var/www/application/public>
            Order Allow,Deny
            Allow from all
            Options -MultiViews
    </Directory>

See the Apache Phusion documentation.
You need to add DocumentRoot and append /public to your Directory config and undo your changes to spawn_manager.rb.

As you noticed, the app_root is one directory up from what is specified.. The parent directory of /home/user/application/public is /home/user/application which is the Rails root.

You want RackBaseURI instead of RailsBaseURI for Rails > 3

The reasoning behind this is so that Apache serves the static assets (which are in the public directory) and then if that isn't present Passenger routes the request to the Rails app.

Ruby on Rails file authorization under RAILS_ROOT/public

If you need access control for your files you don't want to serve them from your public folder. Your public folder is server either by ActionDispatch::StaticFile or directly by your web server - neither of which provide the kind of access controll you want.

Instead you would create a controller which serves up the files:

class FilesController < ActionController::Metal
  before_action :authenticate! # you need to implement this
  before_action :authorize!    # you need to implement this

  # GET /files/:filename
  def show
    path = Rails.root.join(
      'uploads', # can be any directory you want really
       # avoids a malicous user being able to use for example '../../secret/password'
       ActiveStorage::Filename.new(params[:file_name]).sanitized
    )
    if File.exist?(path)
      send_file path
    else
      head :not_found
    end
  end
end

RAILS_ROOT Not Correct When Launching Unicorn with Capistrano deploy on rbenv

From Deefour's comment, I switched from using unicorn_rails to unicorn executable.
