Hi everybody,

I have a datamodel that looks pretty much like this:


class Lead extends DataObject{
    
    private static $db = array(
       ....
    );
    
    private static $many_many = array(
         'Types' => 'Type'
    );

}

class Type extends DataObject{
    
    private static $db = array(
        'Name' => 'Varchar(255)'
    );
    
    private static $belongs_many_many = array(
        'Leads' => 'Lead'
    );
}

Is it possible to do a sort on the Types?

Something like this?


Lead::get()->sort("Types.Name ASC");

Appreciate any help, thanks.

Could you give an idea of what exactly you ar looking for, maybe how the desired endresult would look, based on the example below?

Lead 1 -> Type C, Type A
Lead 2 -> Type A, Type C, Type B
Lead 3 -> Type B, Type A

Hi Martimiz,

Thank you for writting.

Well something like this would be nice:

Lead 3 -> Type A
Lead 89-> Type A, Type B, Type A
Lead 4 -> Type A, Type B, Type C
Lead 22-> Type A, Type B, Type U
Lead 1-> Type B, Type C
Lead 2-> Type C, Type G
Lead 9-> Type K, Type L

I know it's horrible, but is it possible?

What's even more challenging is that I'm using it in a pagination...

Hey Joel,

Could you reverse how you’re accessing the data to achieve this? E.g:

$leads = Type::get()->sort('Name')->relation('Leads');
