You do either. That is, a model can have a $hasOne association that is empty. Your data from a find() would just return an empty array for Passport or NationalDocument (whichever didn't exist). But, if the model can only have one or the other, it might be simplest to create a more general model, eg. Credential. That model could either be extended by Passport and NationalDocument, or it could be associated with a CredentialType model whose table was a list of types. It really depends on whether you need other firleds for Passport and NationalDocument. > The second question would be: how can I change the form fields dynamically > in the view depending of the person being native or foreign?

What information do you require in either case? If it's only, eg. a number, you could use a single field in conjunction with a checkbox, neither of which directly corresponds to an actual Person field. In beforeValidate, look at the checkbox value and create the association array according to it. Then assign to it the text element value. Can't really suggest much more without knowing what the information is that you require, though.
