Hello,

I try to show the link of DataObject but I've an error :
[User Error] Uncaught Exception: Object->__call(): the method 'fortemplate' does not exist on 'Page'

My code :
class BlockHome extends DataObject
{
   static $db = array (
      'Title' => 'Varchar(255)',
      'Description' => 'HTMLText',
      'Link' => 'Int',
      'Order' => 'Int'
   );
   
   static $has_one = array (
      'Attachment' => 'Image',
      'HomePage' => 'HomePage'
   );
   
   public static $summary_fields = array(
      'Attachment.StripThumbnail' => '',
    'Title' => 'Titre'
   );
   
   public function getCMSFields()
   {
       $thumbField = new UploadField('Attachment', 'Image');
    $thumbField->allowedExtensions = array('jpg', 'png', 'gif');
   
    return new FieldList(
    new TextField('Title', 'Titre'),
    new TextareaField('Description', 'Description'),
    new TreeDropdownField('Link', 'Lien', 'SiteTree'),
    $thumbField
    );
   }
   
   public function getUrl()
   {
      if($this->Link)
      {
         $doSet = SiteTree::get()->byID($this->Link);
         
         return $doSet ? $doSet : false;
      }
      
      return false;
   }
}

class HomePage extends Page
{
   static $icon = 'homepage/images/icon';
   static $allowed_children = "none";
   
   public static $has_many = array(
      'Blocks' => 'BlockHome'
   );

   function getCMSFields()
   {
       $fields = parent::getCMSFields();
   
       $gridFieldConfig = GridFieldConfig::create()->addComponents(
           new GridFieldToolbarHeader(),
        new GridFieldAddNewButton('toolbar-header-right'),
        new GridFieldSortableHeader(),
        new GridFieldDataColumns(),
        new GridFieldPaginator(10),
        new GridFieldEditButton(),
        new GridFieldDeleteAction(),
        new GridFieldDetailForm(),
        new GridFieldSortableRows('Order')
    );
   
    $gridField = new GridField("Blocks", "Blocks :", $this->Blocks(), $gridFieldConfig);
   
    $state = $gridField->State->GridFieldSortableHeader;
    $state->SortColumn = 'Order';
    $state->SortDirection = 'asc';
   
    $fields->addFieldToTab("Root.Blocks", $gridField);
         
       return $fields;
   }
}

class HomePage_Controller extends Page_Controller
{
   public function init()
   {
      parent::init();
      
      Requirements::javascript("mysite/js/jquery.anythingslider.min.js");
      Requirements::css('mysite/css/anythingslider.css');
   }
}

My template :
<% if Blocks %>
   <div id="extra">
      <% loop Blocks %>
         <a href="$getUrl" title="$Title">$Title</a>
         ...
      <% end_loop %>
   </div>
<% end_if %>

Can you help me ?

Thanks

I resolved this problem.

In my template, the tag must be $getUrl.URLSegment
