title: Separate identical field names for filters - Ruby on Rails
body: <p>My active admin project has 2 table fields with identical name(created_at) on 2 separate tables(complaints and sales order) and i must enter 2 filters on a ruby page from the admin folder.
  For example :</p>
  
  <pre><code>filter :created_at ,label: "Sales Order Created At:"
  filter :created_at ,label: "Complaint Created At:"
  </code></pre>
  
  <p>How can i differentiate the two fields?</p>
