【问题描述】：

enter image description here当我在树视图 one2many 字段中选择第 1 天这样的选择字段值并且不应该重复第 1 天时，它应该从第 2 天“天”开始：fields.selection([(1,'Day- 1'), (2,'Day-2'), (3,'Day-3'),(4,'Day-4'), (5,'Day-5')],'Day'),在odoo中

enter image description here

【问题讨论】：

添加默认值="2"
图片中重复的记录显示不应该显示
你可以继续 onchange
不应重复选择字段值
@api.onchange('day') def _day_change(self): res= {} if self.env.context.get('day'): crm_team_members_ids = self.env[current_model]。 search([('day', '不在', self.env.context.get('dat')[0][2])]) crm_sp_ids= crm_team_members_ids.ids dayslist = list(set(crm_sp_ids)) res[ 'domain'] = {'day':[daylist]} 返回 res

【解决方案1】：

@api.onchange('week1_meals_id','week2_meals_id','week3_meals_id','week4_meals_id') def _onchange_amount(self): 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]
