python - 属性错误 : object has no attribute

Question

在我的自定义 Odoo 模块中，我必须在单击按钮时调用 python 函数。我按照文档中的确切方式进行操作。但是我得到如下错误..AttributeError: 'book.meeting' 对象没有属性 'checkout_function'

我的代码如下..

class BookMRoom(models.Model):
 _name="book.meeting"



 name=fields.Char(string="Enter booking person name",required=True)
 company_name=fields.Many2one('res.company','Enter your company name',required=True)
 start_time=fields.Datetime(string="Starting date",select=True,required=True)
 end_time=fields.Datetime(string="Ending date",select=True)
 meeting_room=fields.Many2one('mroom', 'select the room',required=True)
 room_info=fields.Many2one(comodel_name='mroom', field='description')
 amenities=fields.Many2one('mroom','Select amenities')
 ob =fields.Many2one('mroom')

 @api.multi
 def checkout_function(self,cr,uid,ids,context=None):
    #raise Exception('Coming Inside Checkout Function')
    current_time = datetime.now().strftime('%Y-%m-%d %H:%M:%S')
    self.end_time=current_time
    meeting_obj=self.env['mroom']
    meeting_room.status='available'
    return meeting_room.status

我的 XML 文件..

<record model="ir.ui.view" id="book-form">
   <field name="name">book.meeting.form</field>
   <field name="model">book.meeting</field>
   <field name="type">form</field>
   <field name="arch" type="xml">
 <form string="booking_view_form">
        <sheet string="Book meeting room">
          <label for="name" string="Booking person name"/>      
          <h1>
             <field name="name" placeholder="Booking person" class="oe_inline" string="Booking person"/>
          </h1>
          <group>
             <group>
                 <field name="company_name" string="Company name"/>

                 <field name="meeting_room" string="select a room" options="{'no_quick_create':True,'no_create_edit':True}"/>

         <button string="Check Out" name='checkout_function' type="object"/>
             </group>
          </group>
        <notebook>
           <page string="Room description">
               <field name="room_info"/>
           </page>
           <page string="Amenities of the room">
           </page>
        </notebook>
        </sheet>
     </form>
   </field>
 </record>

 <record model="ir.actions.act_window" id="booking_action">
     <field name="name">Book meeting room</field>
     <field name="res_model">book.meeting</field>
     <field name="view_type">form</field>
     <field name="view_mode">tree,form</field>
     <field name="view_id" ref="book-tree"/>
     <field name="help" type="html">
          <p>To book a meeting room click create</p>
 </field>
 </record>

谁能帮帮我？

Answer 1

在你的情况下，问题基本上是因为你没有正确升级你的自定义模块，并且可能在创建你的方法后没有从终端重新启动 odoo 服务器。

第二点很重要，您可以听到 cr,uid,ids,context=None 在模型(类)的新 API 装饰器方法中使用不需要的方法参数。

请尝试检查重新启动 odoo 服务器，然后检查该模块操作的影响。

希望我的回答对你有帮助:)
