odoo框架需求：假如有用户表订单表 现在需要让用户审核订单，审核人不能是订单表的申请人，这个方法如何实现请写出完整代码

在Odoo框架中实现该需求，需要进行以下步骤：

1. 定义用户表和订单表的模型

from odoo import models, fields

class User(models.Model):
    _name = 'myapp.user'
    
    name = fields.Char()
    email = fields.Char()
    ...

class Order(models.Model):
    _name = 'myapp.order'
    
    name = fields.Char()
    user_id = fields.Many2one('myapp.user')
    status = fields.Selection([('draft', 'Draft'), ('pending', 'Pending'), ('approved', 'Approved')], default='draft')
    ...

2. 创建订单审核模型，并继承订单模型

class OrderApproval(models.Model):
    _name = 'myapp.order_approval'
    _inherits = {'myapp.order': 'order_id'}
    
    order_id = fields.Many2one('myapp.order', required=True, ondelete='cascade')
    approved_by = fields.Many2one('myapp.user', string='Approved By')
    ...

3. 定义订单审核流程

class OrderWorkflow(models.Model):
    _name = 'myapp.order_workflow'
    
    def action_approve(self):
        for rec in self:
            if rec.order_id.status == 'pending' and rec.approved_by != rec.order_id.user_id:
                rec.order_id.status = 'approved'

4. 将订单审核模型添加到菜单中

<odoo>
    <data>
        <menuitem id="menu_order_approval" name="Order Approval" parent="base.menu_sales" sequence="10"/>
        <record id="view_order_approval_form" model="ir.ui.view">
            <field name="name">Order Approval Form</field>
            <field name="model">myapp.order_approval</field>
            <field name="arch" type="xml">
                <form string="Order Approval">
                    <sheet>
                        <group>
                            <field name="name"/>
                            <field name="user_id"/>
                            <field name="status"/>
                            <field name="approved_by"/>
                            ...
                        </group>
                    </sheet>
                </form>
            </field>
        </record>
        <record id="action_order_approval" model="ir.actions.act_window">
            <field name="name">Order Approval</field>
            <field name="res_model">myapp.order_approval</field>
            <field name="view_mode">tree,form</field>
        </record>
        <menuitem id="menu_order_approval_list" name="Order Approval" parent="menu_order_approval" action="action_order_approval"/>
    </data>
</odoo>

5. 进行权限设置，使只有审核人才能操作

<odoo>
    <data>
        <record id="group_order_approval_user" model="res.groups">
            <field name="name">Order Approval User</field>
        </record>
        <record id="rule_order_approval_access" model="ir.rule">
            <field name="name">Order Approval Access</field>
            <field name="model_id" ref="myapp.model_myapp_order_approval"/>
            <field name="domain_force">[('approved_by', '=', user.id)]</field>
            <field name="groups" eval="[(4,ref('myapp.group_order_approval_user'))]"/>
            <field name="perm_read" eval="True"/>
            <field name="perm_write" eval="True"/>
            <field name="perm_create" eval="False"/>
            <field name="perm_unlink" eval="False"/>
        </record>
    </data>
</odoo>

以上是实现Odoo框架中的订单审核需求的完整代码，该代码具体实现了订单审核的业务逻辑和权限控制。
