DataMapper ORM v1.8.2

Indeed.

Adding new properties in general is not a good idea, as it might interfere with future use of the model.

In cases where I have a need for it, I create a property "protected $_custom = array()", and use setters and getters to work with values in this array. This way you can add custom data as much as you want, without tainting the object.

You can use the rules and get rules to populate this property if it's values are related to data you read or write.

Code:

class Modelname extends Datamapper
{
    protected $_custom = array();

    public function get_custom($name)
    {
        return isset($this->_custom[$name]) ? $this->_custom[$name] : NULL;
    }


    public function set_custom($name, $value = null)
    {
        if ($value === NULL)
        {
            if (isset($this->_custom[$name]))
            {
                unset($this->_custom[$name]);
            }
        }
        else
        {
            $this->_custom[$name] = $value;
        {
    }
}
