title: Ruby on rails form_tag - sending model parameters to controller
body: <p>Controller: <code>@micropost = Micropost.new(params[:micropost])</code></p>
  
  <p>But this form_tag is sending me <code>params[:content]</code> instead of <code>params[:micropost][:content]</code></p>
  
  <pre><code>&lt;%= form_tag( {:controller =&gt; :microposts, :action =&gt; :create}, :remote =&gt; true) do %&gt;
  
      &lt;%= text_area_tag :content, "", :size=&gt; "20x2" %&gt;
      ...
      ...
      ...
      &lt;%= submit_tag "submit" %&gt;
  &lt;% end %&gt;
  </code></pre>
  
  <p>server:</p>
  
  <pre><code>Processing by MicropostsController#create as JS
  Parameters: {"utf8"=&gt;"✓", "content"=&gt;"sdfsdf", "commit"=&gt;"submit"}
  </code></pre>
