[quote author="jpi" date="1248903820"]$vehicles->all is an array where each row is a record in your database AND a vehicle object. When a vehicle objet is instantiate the property time_on_the_road and miles_driven should be empty (as they dont refer to a column in your DB). There is no "cached value".[/quote]
Ah that makes sense, each row is a seperate instance of the model, gotchya.

If you wanted to make this really seamless, try using the magic __get method:

That is pretty neat but it's going to be one ugly method with one huge switch statement what with all the properties I'm going to be caching like this. Hmm.. how's about:

Code:

function __get($field){
  $met = 'calc_'.$field; // give us a convention for these calculating methods
  if(method_exists($this,$met)){
    return $this->$met(); // sets $this->$field and returns it
  }
  return parent::__get($field);
}

Then I can just add the __get() method to DataMapper and then each calc_property_name() method would just work. Good idea or ridiculous idea?
