Modal window for edit model in Sonata Admin

Manually you can do it yourself.

1. Add in your config service

   calls:
   - [ setTemplate, [list, AcmeYourBundle:Your:base_list.html.twig]]
   - [ setTemplate, [edit, AcmeYourBundle:Your:base_edit.html.twig]]
   

2. In your admin bundle add custom templete in configureListFields

   protected function configureListFields(ListMapper $listMapper) {
     $listMapper
       ->add('_action', 'actions', array(
         'actions' => array(
           'edit' => array('template' => 'AcmeYourBundle:Your:_action_edit.html.twig'),
         )
       ));
   }
   

3. _action_edit.html.twig

   {% if admin.hasRoute('edit') and admin.id(object) and admin.isGranted('EDIT', object)%}
     <a class="edit sonata-action-element" href="{{ admin.generateObjectUrl('edit', object) }}">
       <i class="fa fa-edit"></i>
       {{ 'link_action_edit'|trans({}, 'SonataAdminBundle') }}
     </a>
   {% endif %}
   

4. Add javascript code in base_list.html.twig

   <script type="text/javascript">
     $(document).ready(function() {
       $('a.edit').click(function() {   //bind handlers
           var url = $(this).attr('href');
           showDialog(url);
           return false;
       });
   
       $("#targetDiv").dialog({
         autoOpen: false,
         height: 700,
         width: 950,
         modal: true
       });
   
       function showDialog(url) {  
         $("#targetDiv").load(url);
         $("#targetDiv").dialog("open");
       }
     });
   
   </script>
