Hello again :)
I'm still implementing validations and got a new problem. I would like to put all my POST data into my model object and validate two of the fields. In this case it password and password_confirm. When I use them in my own Validator I can't access to "password_confirm" because it is not an existing column in the database. So the question is, how can I access all the data given in the model. By the way it is not only $_POST it can be also differ.
I saw already that the value which is required to compare are in the snapshot.
