明细有数据时，主档的书店不让编辑

class st_book4(models.Model):
    _name = 'st.book4'
    _description = u'书箱出库'

    name = fields.Char(u'单据编码', default=False)
    date = fields.Date(u'日期')
    state = fields.Selection([('draft',u'草稿'),('done',u'确定'), ],u'状态',
                             readonly=False, required=True, default='draft')

    book4_id = fields.Many2one('st.bookstore',  u'书店', required=False,)
    storage3_ids = fields.One2many('st.storage2', 'master2_id', u'入库明细', required=False)

上面是book4，是主档代码
下面是明细字段：

class st_storage2(models.Model):
    _name = 'st.storage2'
    _description = u'出库详细'

    code = fields.Char(u'序号', default=False)
    number = fields.Float(u'出库数量', digits=(16, 2))
    master2_id = fields.Many2one('st.book4', u'书箱入库', required=False,)
    aaa_id = fields.Many2one('st.book3', u'书目', required=False,)
    name = fields.Char(related='aaa_id.name',string=u'书名', default=False)
    samount = fields.Float(u'销售单价',related='aaa_id.samount', digits=(16, 2))
    to_pri = fields.Float(u'销售总价', digits=(16, 2))

    amount = fields.Float(u'单价',related='aaa_id.amount', digits=(16, 2))
    tatol = fields.Float(u'金额',related='aaa_id.tatol', digits=(16, 2))

似乎st_storage2有值跟book4_id完全没有关系，问题应该在别的地方
