Answer 1

@ api.onchange（ 'week1_meals_id'， 'week2_meals_id'， 'week3_meals_id'， 'week4_meals_id'） DEF _onchange_amount（個體）： 天= []

if len(self.week1_meals_id) >5 or len(self.week2_meals_id) >5 or len(self.week3_meals_id) >5 or len(self.week4_meals_id) >5: 
     raise osv.except_osv(_('Error!'),_('Only 5 days per week!!')) 

    for lp in [self.week1_meals_id, self.week2_meals_id, self.week3_meals_id, self.week4_meals_id]: 
     for i in lp: 
      if i.day in days: 
       raise osv.except_osv(_('Error!'),_('Meals for this day already exists!!')) 
      else: 
       days +=[ i.day]
