How could I create a wizard, whose function is to select a date and a value and copy it to another date.

suppose it is a film that has a session with some values ​​(room, time, film), and this by a certain date the wizard should select the date 1 and the session and date 2 (where to copy the session date 1). Help please.

I have made this part of the code:

**from osv import osv, fields class cinema_move_sessions(osv.osv_memory): _name = 'cinema.move.sessions'

_columns = {
'info_updates': fields.integer('Number of updated rates',readonly=True),
'date_inicial': fields.date('Date Initial'),
'date_final': fields.date('Date Final'),
'sessions_ids': fields.many2one('cinema.sessions', 'Sessions', required=True),
'state':fields.selection([ ('init','Init'), ('done','Done'), ],'State',readonly=True)
}

_defaults = { 
'state': lambda *a: 'init'
}

cinema_move_sessions()**
