Rails 3: Display variable from controller in view

Question

I'm pretty new to rails and I was wondering how I can display a variable from my controller into my view.

Basically, I have 2 files: articles_controller.rb and _article.html.erb

In my controller file I have a variable @article_votes that I want to display on my view. I've tried using <%= @article_votes %> but it does not display anything at all.

Would anyone have any guidance? Thank you!

Not sure how new you are to rails. Any instance variable you define inside your controller is reachable inside the views.

So, if @article_votes is defined in the controller, writing

<pre>   <%= @article_votes.inspect %> </pre> 

somewhere in your view should show up in your page.

But the _article.html.erb is not shown by default. If you have a show method in your ArticlesController, the view called show.html.erb is rendered. This is a general approach, so for the index method, it should be called index.html.erb.

Hope this helps.
