    Is it possible in Akelos to set something like this in a model (example from api.rubyonrails.com):

    class User < ActiveRecord::Base
   def full_name
     "#{first_name}. #{last_name}"
   end
end

    So I could use:

    $User->collect($User->findBy('role_id',2),'full_name','id')

    .. in a view to make a selection menu with the full names of people?

    this would be

    class User...
function getFullName()
{
    return $this->firstname . $this->lastename;
}

    ah, okay.

    Didn't know I should use get + camelcased name, because I tried:

    function full_name()
{
   return $this->first_name.' '.$this->last_name;
}

    .. but that didn't work.

    Thanks!

    aha, so that's what virtual or transparent attributes are, being discussed in this post. (learning new tricks every day)

    I’ve got another one: I want to make a collection of a model that does not have a name column, the names are defined by a belongs_to association to another column (energysourcename) which has localized name columns.

    So I could do this:

    function getName()
{
   $this->energysourcename->load();
   return $this->energysourcename->{$_SESSION['lang'].'_name'};
}

    But maybe there's a nicer, shorthand way of doing it without using $_SESSION['lang'] ?

    .

    ->getCurrentLocale()

    Or try with

    class Person extends ActiveRecord
{
    var $combined_attributes = array(array('name', "%s %s", 'first_name', 'last_name'));
}

    Now you can user Person->get('name')
