They tell me my problem is solved as follows
This is fixed in the 2.0.x branch (Phalcon 2.0.4), you have to change a global ORM setting to allow unexpected columns:
\Phalcon\Mvc\Model::setup(['ignoreUnknownColumns' => true]);
I would like to know how to make that change
try in the initialize method of your models, using self::setup() or maybe a magic setter exist for that, a this time the API of models don't list such a thing in the doc...
I don't understand a quesion, you can just add this code anywhere, it's using globals so it will work pretty much anywhere.
Either do as @Jurigag suggested, or put this line into your relevant php.ini file:
phalcon.orm.ignore_unknown_columns = 1
