Hi, I’m new to silverstripe, and I’m trying to evaluate if I want to use silverstripe for my next projects.

I love it so far but I’m running into a problem with the DataObject and the Gridfield.

I created a dataobject that has a file via $has_one now what I’m trying to do is to have a link to this file in the Gridfield via the $summary_fields but I do not have any luck yet, does anybody knows of a good tutorial on how to do this? Also I like to add additional action buttons to it, a tutorial on that would also be greatly appreciated.

I don't have an answer for you right away, but have you seen the great new lessons department here: http://www.silverstripe.org/learn/lessons/

There's a brand new lesson on ModelAdmin (13) and it might give you some hints on casting and formatting gridfield datacells...

You can create a method to get the link to the file, and return it in your $summary_fields. I made you a paste as an example, I haven't tested it, but it should set you on the right direction: http://www.sspaste.com/paste/show/55020854ce4f5

Thanks Rhym,

That worked great, the only thing is that it escaped the link html so I changed

 
if($this->File()->ID) {
      $html = '<a href="'.$this->File()->Link().'">'.$this->File()->Name.'</a>';
      return $html;
}

To

 
if($this->File()->ID) {
      $link= HTMLText::create();
      $link->setValue('<a href="'.$this-> File ()->Link().'" target="_blank"><div>'.$this-> File ()->Name.'</div></a>');
      return $link;
}

and now it displays the html correctly

Did you solve the "problem" that the gridfield item also gets opend?
