Rails form keeps returning a nomethoderror

        <%= form_for rating_ballot, :html => { :class => 'rating_ballot' } do |f| %>
            <%= f.label("value_1", content_tag(:span, '1'), {:class=>"rating", :id=>"1"})
            radio_button_tag("rating[value]", 1, current_user_rating == 1, :class => 'rating_button') %>
            <%= f.label("value_2", content_tag(:span, '2'), {:class=>"rating", :id=>"2"})
            radio_button_tag("rating[value]", 2, current_user_rating == 2, :class => 'rating_button') %>
            <%= f.label("value_3", content_tag(:span, '3'), {:class=>"rating", :id=>"3"})
            radio_button_tag("rating[value]", 3, current_user_rating == 3, :class => 'rating_button') %>
            <%= f.label("value_4", content_tag(:span, '4'), {:class=>"rating", :id=>"4"})
            radio_button_tag("rating[value]", 4, current_user_rating == 4, :class => 'rating_button') %>
            <%= f.label("value_5", content_tag(:span, '5'), {:class=>"rating", :id=>"5"})
            radio_button_tag("rating[value]", 5, current_user_rating == 5, :class => 'rating_button') %>

            <%= hidden_field_tag("message", msg.message) %>
            <%= f.submit :Submit %>
        <%- end -%>

This is my form, I'm trying to create a system for users to rank messages in a "star" system form this tutorial. I have followed all the instructions on the tutorial but when I include this form I get a nomethoderror undefined method 'ratings_path'. In my home_helper I have

  def rating_ball开发者_运维知识库ot
    if @rating = current_user.ratings.find_by_id(params[:msg])
      @rating
    else
      current_user.ratings.new
    end
  end

  def current_user_rating
    if @rating = current_user.ratings.find_by_id(params[:msg])
      @rating.value
    else
      "N/A"
    end
  end

Why am I getting this error? Thanks

This is a routing problem. *_path are known as path helpers. Run rake routes to see what routes you have. You'll likely need to add new routes for your actions in order to use the path helpers. From your code, I'm guessing you'll need:

resources :ratings

But it's anyones guess what the rest of your application looks like.
