python之预期单例 : hr. employee(1, 2)

美好的一天!我在加载 kanban View 时出错。我继承了 hr.employee Kanban xml 并且只添加了一个条件，如果某些文件过期，它会在 kanban View 中添加一个 Expired Documents 通知，这里是 xml 代码:

    <record model="ir.ui.view" id="hr_kanban_view_employees_recruitment_kanban"> 
        <field name="name">HR - Employees Kanban Document Status</field> 
        <field name="model">hr.employee</field> 
        <field name="inherit_id" ref="hr.hr_kanban_view_employees"/> 
        <field name="arch" type="xml"> 
            <xpath expr="//templates" position="before"> 
                <field name="employee_id"/> 
                <field name="documents_status"/> 
            </xpath> 
            <xpath expr="//div[@class='oe_employee_details']/ul/li[@id='last_login']" position="inside"> 
                <span t-if="record.documents_status.raw_value" style="font-size: 100%%" 
                        t-att-class="record.documents_status.raw_value==true'oe_kanban_button oe_kanban_color_3'"> 
                    <field name="employee_id" readonly = "1"/> 
                    Has Expired Documents 
                </span> 
            </xpath> 
        </field> 
    </record> 

documents_status 字段的模型

加载时

documents_status = fields.Boolean('DocumentStatus', readonly = True,store = False,compute ='getdocumentStatus') 
 
    @api.one 
    def getdocumentStatus(self): 
        raise Warning(self.employee_id) 
        server_date = datetime.datetime.strptime(DATE_NOW.strftime("%Y-%m-%d") ,"%Y-%m-%d") 
        result = {} 
 
        for id in self.ids: 
            result[id] = { 
                'documents_status': True 
            } 
            totaldoc = self.env['hr.employee_documents'].search_count([('date_expiry', '<', server_date),('employee_doc_id','=', id)]) 
            if totaldoc > 0: 
                result[id]['documents_status'] = True 
                self.documents_status = True 
            else: 
                result[id]['documents_status'] = False 
                self.documents_status = False 
        return result 

员工中的看板 View 发生错误

Expected singleton: hr.employee(1, 2).

有人会帮我解决这个问题吗？在此先感谢。

请您参考如下方法:

我不知道hr.employee 和hr.employee_documents 之间的关系。如果这是一个 One2many(一个唯一员工的许多文档)，则 hr.employee 模型中必须有一个 One2many 字段指向 hr.employee_documents。假设此字段名为 documents(这对于通过 api.depends 触发计算方法很重要)。然后写这段代码:

@api.multi 
@api.depends('documents.date_expiry') 
def getdocumentStatus(self): 
    server_date = datetime.datetime.strptime(DATE_NOW.strftime("%Y-%m-%d"), "%Y-%m-%d") 
    for record in self: 
        totaldoc = self.env['hr.employee_documents'].search_count([('date_expiry', '<', server_date),('employee_doc_id','=', self.id)]) 
        if totaldoc > 0: 
            record.documents_status = True 
        else: 
            record.documents_status = False 

您应该将两种模型之间的关系写给我们，以便给您准确的答案。
