In Ruby 2.1.1 / Rails 4.1.1 the route must be defined manually

[itsjms]

In Ruby 2.1.1 / Rails 4.1.1 to get the route working properly I had to turn the config.automatic_routes_mount to false and manually add mount RailsDb::Engine => "/rails/db", as: 'rails_db' as a route in my application.

BTW for people who don't know - you need to generate config

rails g initializer rails_db

And then edit config/initializers/rails_db.rb and restart app

[igorkasyanchuk]

gem 'rails', '4.1.1' gem 'rails_db' gem 'sass', '>= 3.3.14' gem 'sass-rails', '>= 5.0.0' gem 'foundation-rails', '>= 5.5.0.0'

Everything works well (automatic routes mounting I mean works correctly)
