If I understand you correctly, you'd like to add model attributes that
can be used by the model internally (for validation etc), but not
persisted to the database?
All model data is stored as an associative array (a public attribute)
in the model as $this->data['ModelName']['field_name'], so you can
either directly insert into that array (from within a controller:
$this->Model->data['ModelName']['field_name'] = 'Some Value'; ) , or
use $this->Model->set('field_name', 'Some Value'); (again, assuming
you're setting from the controller). All of this data is available to
$model->validates().
You must create the model data array first: $this->Model-
>create([$modelData]) for a new record, and/or $this->Model-
>set($modelData) for an existing record (where $modelData has already
been retrieved via $this->Model->find() or comes from the controller-
>data ) . Note that model->set has two ways of being used.
If you create a form field 'Model/my_checkbox' this will be in the
controllers data array - which is the same structure as the model data
array so can be used as per the $modelData above.
