Odoo丨手把手教你灵活控制表单明细的创建与删除！

@api.onchange('name_a')    #监听姓名字段def _name_a(self): args_list = [] self.name_rel = None #把关联关系接触，每次触发清楚上次的明细 if self.name_a: purchase_detail = [{             #可以通过sql查询，或者接口获取，拿到想要的明细数据 'name_b': '打篮球',  'time_b': '2年' }] for detail in purchase_detail: num = 1 args = { 'name_b': detail['name_b'], 'time_b': detail['time_b'], } args_list.append((0, 0, args))         #建立odoo规定的关联关系！！ num += 1 self.res_sale_product_detail = args_list          #给关联字段赋值
