如何在odoo 9的qweb模板中从odoo上下文中获取值？

Question

我正在odoo 9中工作。我已经从JS打开了一个向导，并且已经传递了上下文，因此我想在向导中使用此上下文。我怎样才能做到这一点？ 请查看我的代码。

     myfunc: function(e) {
     var mycontext = {};
     var is_checked = this.field_manager.get_field_value('Default')
     if (is_checked)
     {
         var model_obj = new Model('olims.ar_priority');
         var domain = [['Default', '=', true]];
         model_obj.call('search_read',[domain]).then(function(result){
         mycontext['current_priority'] = result[0]['Priority'];
         })
         alert()
         this.do_action({
                            name: ("Pop Up"),
                            res_model: 'olims.ar.priority.wizard',
                            type: 'ir.actions.act_window',
                            view_type: 'form',
                            view_mode: 'form',
                            views: [
                                [false,'form']
                            ],
                            target: 'new',
                            context : mycontext,
                        });
      }

这是xml

   <record model="ir.ui.view" id="olims_ar_priority_confirm_wizard">
    <field name="name">Set Default Priority Wizard</field>
    <field name="model">olims.ar.priority.wizard</field>
    <field name="type">form</field>
    <field name="arch" type="xml">
        <form>
            <group>
                <templates>
                    <t t-set="priority" t-value="request.env.context['current_priority']"/>
                    <span><t t-esc="priority"/>  is set as default</span>
                </templates>
            </group>
            <footer>
                <button string="Cancel" special="cancel" class="oe_highlight"/>
                <button name="agent_exceed_limit" string="Request Manager to Approve Sale" type="object" class="oe_highlight" />
            </footer>
        </form>
    </field>
</record>
