Question

I am attempting to create a login system. My UserController has this to control the new action:

def new
    @user = User.new

    respond_to do |format|
        format.json { render :json => @user }
        format.html
    end
end

and my routes.rb has this to link:

resources :user

The View’s form to create a new user is this:

<%= form_for @user do |f| %>

however, I receive an Action Controller error with this:

undefined method `users_path' for #<#<Class

What has baffled me is why it is using users_path. This is a plural reference to my route. Why is it returning a plural error of user_path?? When I route `resources :users’ it clears the error, but of course I don’t have anything setup for that resource and thus produces other errors.

Answer 1

resources :users is actually the correct structure, since it is a collection of users, not a single user. The route construction also expects a plural path (IIRC, it expects a plural path unless it finds a resource, as opposed to resources route), hence the attempt to use users_path.

Passing an explicit url parameter is another option <%= form_for @user, :url => user_path do |f| %>, since you already have things expecting singular routes
