ruby-on-rails-3.1

Im still new to Rails and have a hard time understanding how the path system works in Rails. In my routes.rb i create an alias for signup: match 'signup' => 'user#new' resource :user, :controller => 'user' The action is there and going to /signup shows the correct action. So far so good. Now, when i submit my signup form it runs the create action with POST as usual. And here is where im stuck. If the signup fails, i would like to present the user with the signup form again. One option would be to do a render "new", but that takes the user to /user instead of /signup. UserController class

I am trying to create 3 nested models at once, and have trouble with my validations. These are my models: class UserEntity < ActiveRecord::Base has_many :users, :dependent => :restrict, :autosave => true end class User < ActiveRecord::Base has_many :user_login_services, :dependent => :destroy, :autosave => true belongs_to :user_entity end class UserLoginService < ActiveRecord::Base belongs_to :user #validates :user_id, :presence => true end (UserEntity can be a company, with many users.

I ran into a problem deploying on Heroku do to a failure in the rake task rake assets:precompile At the bottom is the error I get if I integrate Rails 3.1 Jquery calendar: https://github.com/themouette/jquery-week-calendar Twitter bootstrap The error happens from uglifier.

I also could not get the debugger in RubyMine to stop
