file couldn't find issue it.
railsprelaunchsignup::application.routes.draw root to: "root_path" end user.rb
class user < activerecord::base rolify # include default devise modules. others available are: # :token_authenticatable, :encryptable, :confirmable, :lockable, :timeoutable , :omniauthable devise :database_authenticatable, :registerable, :confirmable, :recoverable, :rememberable, :trackable, :validatable # setup accessible (or protected) attributes model attr_accessible :name, :email, :password, :password_confirmation, :remember_me end any appreciated!
it indeed routes file:
root to: "root_path" this should like:
root to: "controller#action" root_path helper name automatically generated rails when have root definition in routes file.
