How do I access class variable?
<pre><code>class TestController &lt; ApplicationController

  def test
    @goodbay = TestClass.varible
  end
end

class TestClass
  @@varible = "var"
end
</code></pre>

<p>and i get error </p>

<pre><code>undefined method 'varible' for TestClass:Class 
</code></pre>

<p>on the line <code>@goodbay = TestClass.varible</code> </p>

<p>What is wrong?</p>
