odoo 12 自定义 pos 锁屏模块 this.pos 为空

Question

我为 odoo 12 制作了一个模块来锁定 pos 屏幕代码在 odoo 10 中工作正常，但给出错误 this.pos is null or this.pos.currency is undefined。在models.js，我想切换不同收银员的订单，但是this.pos没有初始化，我应该怎么做才能初始化？这是我的代码：

odoo.define('pos_user_lock.models',
//['point_of_sale.models','point_of_sale.screens','point_of_sale.chrome'
//,'web.ajax','web.core'],
function (require) {
"use strict";

var ajax = require('web.ajax');

var screens = require('point_of_sale.screens');

var models = require('point_of_sale.models');

var chrome = require('point_of_sale.chrome');

var core = require('web.core');

var QWeb = core.qweb;

var _t = core._t;

models.Order = models.Order.extend({

    initialize: function(attributes,options){

        var order =  models.Order.__super__.initialize.call(this,attributes,options);

        if (!this.cashier)

        {

            this.cashier = this.pos.cashier || this.pos.user;

        }





        this.is_last_selected = (this.is_last_selected === undefined) ? false:this.is_last_selected;

        return order;

    },

    finalize: function() {

        var res =  models.Order.__super__.finalize.call(this);

        this.pos.lock_user_screen();

    },

    init_from_JSON: function(json) {

        var user = this.get_user_by_id(json.user_id);

        if (user)

            this.cashier = user;

        this.is_last_selected = json.is_last_selected;

        models.Order.__super__.init_from_JSON.call(this, json);

    },

    export_as_JSON: function() {

        var res =  models.Order.__super__.export_as_JSON.call(this);

        if (this.cashier)

            res.user_id = this.cashier.id ;

        if(this.pos && this.pos.get_cashier())

            res.user_id = this.pos.get_cashier().id ;

        res.is_last_selected = this.is_last_selected;

        return res;

    },

    get_user_by_id: function(id) {

        var users = this.pos.users;

        for (var i = 0; i < users.length; i++) {

            var user = users[i];

            if (user.id == id)

                return user;

        }

    },



});



models.PosModel = models.PosModel.extend({

    initialize: function(session, attributes) {

        models.PosModel.__super__.initialize.call(this, session, attributes);



        var self = this;

        alert(JSON.stringify(attributes.pos));

        this.ready.then(function(){

网页显示 this.pos 为空。 this.currency 为空。我通过添加找到了解决方案：

this.pos = this;

在 PosModel 的初始化函数中。
