I told you to read on virtual attributes and callbacks. To give you a clue on what you need to do, you need to create 2 virtual atteibutes: one for the text field and one for the date select. Then use a before validation callback to concatenate them. Or just as colin suggested, concatenate them in the controller but i'd like to so these things in the model.
