Add Ratings and Comments in the same Controller

Question

I have gotten a comment model to work based on railscast 238 but I would like to add voting and rating as well.

My current show for the article controller is:

 def show
    @article = Article.find(params[:id])
    @commentable = @article
    @comments = @commentable.comments
    @comment = Comment.new


    respond_to do |format|
      format.html # show.html.erb
      format.json { render json: @article }
    end
  end

I have tried replicating the same process and adding rateable but I do not know how to integrate it into the show action. I have considered creating a universal function from application controller and then trying to assign it in to multiple things(newb) in the show function but that seems over complicated.

I tried adding:

@rateable = @article
@ratings = @rateable.ratings
@rating = Rating.new

It did not work. But now I am thinking it might work if I assign it to

@ratings = Article.find(params[:id]}
@ratings = @rateable.ratings
@rating = Rating.new

Even if that does work, there must be cleaner way to do this.

Edit:

Error after correction from this line of code, which is identical to the working comment version.

<%= form_for [@rateable, @rating] do |f| %>
  <% if @rating.errors.any? %>
    <div class="error_messages">
      <h2>Please correct the following errors.</h2>
      <ul>
      <% @rating.errors.full_messages.each do |msg| %>
        <li><%= msg %></li>
      <% end %>
      </ul>
    </div>
  <% end %>

  <div class="field">
    <%= f.text_area :content, rows: 8 %>
  </div>
  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>

Answer 1

Okay, think I figured it out. Just change <%= f.submit %> to:

<%= f.submit 'Submit', { controller: 'ratings', action: 'create', method: 'post' } %>

In your routes.rb file you will also need put '/ratings/create' => 'ratings#create' or simply resources :ratings

This will route your form submit to ratings#create which I think is what you want.
