title: Rails POST params empty after submit?
body: <p>i have a strange rails 3.2 problem. when i submit a form like this:</p>
  
  <pre><code>&lt;%= form_for @job, :url =&gt; job_preview_path do |f| %&gt;
  &lt;dl&gt;
    &lt;dt&gt;&lt;%= f.label :job_title, "Job Titel" %&gt;&lt;/dt&gt;
    &lt;dd&gt;&lt;%= f.text_field :job_title %&gt;&lt;/dd&gt;
    &lt;dt&gt;Checkbox please!&lt;/dt&gt;
    &lt;dd&gt;&lt;%= f.check_box :extra_featured %&gt; &lt;/dd&gt;
  &lt;/dl&gt;
  &lt;%= f.submit "Submit" %&gt;&lt;/p&gt;
  &lt;% end %&gt;
  </code></pre>
  
  <p>where the action route is defined as</p>
  
  <pre><code>match 'job/preview' =&gt; 'jobs#preview', :as =&gt; :job_preview, :via =&gt; :post
  </code></pre>
  
  <p>the values of the POST params stay empty after submit except for the check_box value. In the action in my controller after the submit, I reassigned the params to the model, so I can reuse the params for saving the entry.</p>
  
  <pre><code>def preview
    @job = Job.new(params[:job])
  end
  </code></pre>
  
  <p>any advice on this strange behaviour? am i blind and don't see the bug?</p>
