title: form_tag not rendering in rails 3.2
body: <p>I am following the tutorial at <a href="http://www.noupe.com/ajax/create-a-simple-twitter-app.html" rel="nofollow">http://www.noupe.com/ajax/create-a-simple-twitter-app.html</a>
  I am using ruby version 1.9.3p194 , rails version 3.2</p>
  
  <p>When I created the view file index.html.erb , and put in the contents as </p>
  
  <pre><code>&lt;b&gt;&lt;%= render :partial =&gt; "message_form" %&gt;&lt;/b&gt; 
  &lt;%= render :partial =&gt; @posts %&gt;  
  </code></pre>
  
  <p>and then in the form partial , _message_form.html.erb</p>
  
  <pre><code> In partial _message_form
  &lt;% form_tag(:controller =&gt; "posts", :action =&gt; "create", :method=&gt;"post") do %&gt;  
    &lt;%= label_tag(:message, "What are you doing?") %&gt;&lt;br/&gt;  
    &lt;%= text_area_tag(:message, nil, :size =&gt; "44x6") %&gt;&lt;br/&gt;   
    &lt;%= submit_tag("Update") %&gt;  
  &lt;% end %&gt;
  </code></pre>
  
  <p>and load the index.html.erb , I only see the message "In partial _message_form" . the form tags do not render at all.</p>
  
  <p>Need help. Would be glad to provide any additional required information </p>
