我使用One2many字段扩展了'account.analytic.account'模型,该字段引用了具有One2many字段的第二个模型.

当我尝试从compute方法迭代第二个One2many字段时,它只列出刚刚添加的记录.在保存父记录之前,先前的记录(在界面上可见)在使用"自我"上下文的代码中不可见.

例:

for line in self.One2manyField:
    #only gets here for records I add during current session, or all records if parent is saved
    #how can I see previously saved records? 

这是代码:

1.)扩展'account.analytic.account'模型

class account_analytic_account(models.Model):

    _inherit = ['account.analytic.account']

    service_location_ids = fields.One2many(comodel_name='contract.service.location', inverse_name='contract_id', copy=True)

2.)首先引用One2many模型:

class Contract_Service_Location(models.Model):
    _name = 'contract.service.location'
    _description = 'Service Location Record'  

    #problem is here!
    #compute method for subtotal field
    @api.one    
    @api.depends('recurring_line_ids','recurring_line_ids.price_subtotal')
    def _compute_subtotal(self):
        total = 0.0

        #I tried to get previously saved ids, but returns nothing, until …
