如何用动态字段odoo10过滤树视图

Question

我向res.user添加了“location\u id”字段以将用户连接到某个位置

类继续器（models.Model）： _inherit='res.users'

current_location_id=fields.Many2one('physical.location',string="Current Loction")
allowed_location_ids=fields.Many2many('physical.location',string="Allowed Location")

我只想筛选当前位置id=用户当前位置id的访问

<filter string="My visits" name="filter_my_visits"
                        domain="[('current_location_id','=',current_location_id)]"/>

将显示此错误消息

    Uncaught Error: Failed to evaluate search criterions: 
{"code":400,"message":"Evaluation Error","data":{"type":"local_exception","debug":"Local evaluation failure\nNameError: name 'current_location_id' is not defined\n\n{\"domains\":[[],\"[('current_location_id','=',current_location_id)]\"],\"contexts\":[{\"lang\":\"en_US\",\"tz\":false,\"uid\":1,\"params\":{\"action\":354,\"min\":1,\"limit\":80,\"view_type\":\"list\",\"model\":\"visit.visit\",\"menu_id\":241,\"_push_me\":false}},{}],\"group_by_seq\":[]}"}}

视图中唯一可直接调用的字段是uid lang。。。等 所以我试图重写read方法来更新上下文，但它似乎没有在视图中更新，仍然给出未定义的“当前位置id”

    @api.multi
    def read(self, fields=None, load='_classic_read'):
        ctx = self.env.context.copy() 
        ctx.update({ 'user_current_location_id':self.env.user.current_location_id.id})

        return super(Visit,self.with_context(ctx)).read(fields=fields,load=load)

访问树视图

 <record id="visit_visit_tree_view" model="ir.ui.view">
    <field name="name">visit.visit.tree</field>
    <field name="model">visit.visit</field>
    <field name="arch" type="xml">
        <tree string="Visits">
            <field name="name" />
            <field name="date"/>
            <field name="visit_type" />
            <field name="patient_id"/>
            <field name="hcp_id"/>
            <field name="current_location_id" />
            <field name="user_current_location_id"/>
            <field name="severity"/>
            <field name="state"/>
        </tree>
    </field>
</record>

访问操作

<record id="visit_visit_act" model="ir.actions.act_window">
    <field name="name">Visit</field>
    <field name="res_model">visit.visit</field>
    <field name="view_type">form</field>
    <field name="view_mode">tree,form</field>
    <field name="context">{'search_default_filter_my_visits':1}</field>
    <field name="search_view_id" ref="view_visit_filter"/>
</record>

以下是我所做的：

 @api.multi
def vsit_action(self):
    ctx = self.env.context.copy()

    ctx.update({'search_default_current_location_id': self.env.user.current_location_id.id,
                'user_current_location_id': self.env.user.current_location_id.id})
    return {
        'name': 'Visit',
        'view_type': 'form',
        'view_mode': 'tree,form',
        'res_model': 'visit.visit',
        'type': 'ir.actions.act_window',
        'context': dict(ctx),
        'search_view_id': self.env.ref('eroyal_visit.view_visit_filter').id
    }

过滤器：

    <filter string="My visits" name="filter_my_visits"
                            domain="[('current_location_id', '=', context.get('user_current_location_id'))]"/>


the visit action
     <record id="visit_visit_act" model="ir.actions.server">
        <field name="name">Visit</field>
        <field name="model_id" ref="model_visit_visit"/>
        <field name="state">code</field>
         <field name="code">
                action = env['visit.visit'].vsit_action()


         </field>
    </record>

默认的搜索当前id工作正常，但筛选筛选器我的访问确实筛选当前位置为“无”的视图，而其在上下文中的设置正确 坦克
