用odoo 10创建多个记录

Question

这是我的函数create（）：

api.model
def set_student_level(self):
    for record in self:
        if record.student_ids:
            for student in record.student_ids:
                update_student_ids = self.env['ecole.partner.school'].browse(self.env.context.get('active_ids'))
                if update_student_ids:
                    for rec in update_student_ids:
                        partner = update_student_ids.partner_id.id
                        school_year = update_student_ids.school_year.id
                        school_name = update_student_ids.school_name.id
                        school_level = update_student_ids.school_level.id
                        half_pension = update_student_ids.half_pension
                        half_pension_name = update_student_ids.half_pension_name.id
                        half_pension_begin_date = update_student_ids.half_pension_begin_date
                        half_pension_end_date = update_student_ids.half_pension_end_date
                        nursery = update_student_ids.nursery
                        nursery_name = update_student_ids.nursery_name.id
                        nursery_begin_date = update_student_ids.nursery_begin_date
                        nursery_end_date = update_student_ids.nursery_end_date

                    #Ecriture en dur dans la BDD
                        vals = {'partner_id': partner,
                                'school_year': school_year,
                                'school_name': school_name,
                                'school_level': school_level,
                                'half_pension': half_pension,
                                'half_pension_name': half_pension_name,
                                'half_pension_begin_date': half_pension_begin_date,
                                'half_pension_end_date': half_pension_end_date,
                                'nursery': nursery,
                                'nursery_name': nursery_name,
                                'nursery_begin_date': nursery_begin_date,
                                'nursery_end_date': nursery_end_date}

                        res = update_student_ids.create(vals)

                    return res

我的问题是，当我选择一条记录并单击按钮set_student_level，插入操作会在数据库中工作。但是，当我选择多个记录时，会出现一个错误(ValueError: Expected singleton: school.partner.school (15, 68))。在

这里update_student_ids将是一组记录。所以您应该在for循环中将update_student_ids替换为rec。在

例如：

for rec in update_student_ids:
    partner = rec.partner_id.id
...
