title: ActiveAdmin custom values entered into form fields
body: <p>I have an ActiveAdmin project in Rails 4. For some reason when I use the <code>:value =&gt; some_value</code> for a field nothing changes. It just shows up as an empty text field.</p>
  
  <p>Here's an example of my form:</p>
  
  <pre><code>form do |f|
    f.inputs "Template Details" do
    f.input :inventory_type, :value =&gt; "test"
    f.input :body_type
    f.input :section
    f.input :formula
    f.input :trait
  end
  f.actions
  </code></pre>
  
  <p>The inventory_type field is blank when it renders. I've tried all the other fields with similar results.</p>
