Acces to controller from a attribute type

Permalink
Hi,

I'm working on my free package 'fileset_attribute' to improve it a bit. I would add some function int the controller to help people to work with. in this way i will add for example the function 'getFileListObjectValue' to get a files list object from the fileset.

BUT.. How to access to this special function from a View? It seems that before 5.6 we has able to specify a special function to get value, but now ? It's semmes that is impossible ?

I've tryed some tricks without result.. 

$c = Page::getCurrentPage();
$cc = Collection::getByID($c->cID);
$fs = $c->getAttributeValueObject('fileset'); // Fatal error:  Call to a member function getAttributeKeyID() on a non-object
Loader::model('attribute/categories/collection');
$attribs = $cc->vObj->getAttribute('fileset',$c, 'getFileListObjectValue'); // string(1) "1" 
$ak = CollectionAttributeKey::getByHandle('fileset');
if (is_object($ak)) {
   $av = $c->getAttributeValueObject($ak);
   if (is_object($av)) {
      $fr =  $av->getFileListObjectValue('getFileListObjectValue'); // Fatal error
   }
}
// And this work but the controller can't acces to the attribute value ..
$ak = CollectionAttributeKey::getByHandle('fileset');
$satc = new FilesetAttributeTypeController(AttributeType::getByHandle('fileset'));

Thanks a lot !

Like you, I would have expected the special function method to work. Could it just be a case of the override cache?

I may not be fully understanding your question, but I can suggest a different way to set up the function.

I'm no real expert on attribute types, but I did build one recently where I wanted to be able to return the stored data in different formats (as HTML, as a raw array of data, etc), I'm pretty sure this is the same sort of problem you are trying to solve.

When you retrieve an attribute from a page object, the basic way to do this is:
$c->getAttribute('fileset');
This is going to call the function getValue() on your attribute, which really is supposed to return the raw data. With your attribute Seb, you haven't defined a getValue() function, it just falls back to the one in DefaultAttributeTypeController. (which works perfectly fine).

What I found out though, is that getAttribute can be passed a 'display mode' as a second argument. When you do this, concrete uses this second argument to work out the name of the function to call on the attribute.
So if you do this:
$c->getAttribute('my_attribute', 'display');
It's going to call the function getDisplayValue() on the attribute. Or if you called:
$c->getAttribute('my_attribute', 'Array');
It's going to call getArrayValue() on the attribute.

So in your case, maybe you need to call:
$fs = $c->getAttribute('fileset', 'FileListObject');

So it calls your getFileListObjectValue() function of your attribute. That function should be able to do whatever is necessary to build the FileList object and return it.

As a bit of a side note, I recently did a blog post about using your attribute type to create a composer driven photo gallery - to fetch the actual file list I used a hardcoded List Files From Set block.http://www.mesuva.com.au/blog/concrete5/creating-a-composer-driven-...

Ok, you're right, this feature exist sine 5.6.2.1 and i has working on 5.6.1..

So now it works and it will help you for your blog post :-)

For the little sorry, i was searching for site that talk about C5 and click on your on google really by chance. Once n your site i've clicked on the post where you are writing about fileset_attribute. That is the starting point to improve the attribute :-)

Thanks both,

Seb
