Deploy rails app to non-root context - restful_auth not working

apache, passenger, ruby-on-rails, ruby-on-rails-plugins

Solution

Short Answer

- setting `relative_url_root` in `environments/production.rb`

- creating a route called "home" to my home page

- Modifying the scaffolded `restful_authentication` code to redirect to home instead of `/`

Details

If you're having troubles because of the suburi configuration, you should configure the relative_url_root in your environments/production.rb file:

config.action_controller.relative_url_root = "/scalatour"

In my opinion, the problem your describing here is a controller/routes issue and a possible solution may be the next:

1) I would configure these routes:

ActionController::Routing::Routes.draw do |map|
  [...]
  map.home 'home', :controller => 'welcome', :action => 'show'

  map.login "login", :controller => "user_sessions", :action => "new"

  map.logout "logout", :controller => "user_sessions", :action => "destroy"

  map.root :login
end

2) Then the UserSessions controller would look like:

class UserSessionsController < ApplicationController
  before_filter :require_no_user, :only => [:new, :create]
  before_filter :require_user, :only => :destroy

  def new
    @user_session = UserSession.new
  end

  def create
    @user_session = UserSession.new(params[:user_session])
    if @user_session.save
      redirect_back_or_default home_path
    else
      flash[:error] = "Sorry, unrecognized username or password."
      render :action => :new
    end
  end

  def destroy
    current_user_session.destroy
    redirect_back_or_default login_url
    reset_session()
  end
  end

3) Just for completeness, the methods "require_user" and "require_no_user" could be placed at the ApplicationController and would be:

  def require_user
    unless current_user
      flash[:error] = t("You must be logged-in to access this page")
      redirect_to login_path
      return false
    end
  end

  def require_no_user
    if current_user
      redirect_to home_path
      return false
    end
  end

Best regards
