Why - You must set the database table to be used with your query.

Is it a MUST to define all these "protected ...." settings,
i dont wont to work with the  built-in CRUD methods, so i guess that i dont need to define it!?

I have figure out that the problem comes from another direction, a name of a called function was wrong, if i corret this, the error message (i'm confused about the kind of messag) go away. Now the model works well, without setup the datas on top of the modell.
