title: Rails date format in a text_field
body: <p>I have a rails form that displays a date in a text_field:</p>
  
  <pre><code>&lt;%= form.text_field :check_in_date  %&gt;
  </code></pre>
  
  <p>The date is rendered as <code>yyyy-mm-dd</code></p>
  
  <p>I'm trying to figure out how to have it display as <code>mm-dd-yyyy</code></p>
  
  <p>I tried adding this config but it didn't work.  </p>
  
  <pre><code>ActiveSupport::CoreExtensions::Date::Conversions::DATE_FORMATS.merge!(
    :default =&gt; '%m/%d/%Y'
  )
  </code></pre>
