odoo 币别符号显示机制 Monetary

//-------------------------------------------------------------------
basic_fields.js

init: function () {
    this._setCurrency();

//-------------------------------------------------------------------

_setCurrency: function () {
    var currencyField = this.nodeOptions.currency_field || this.field.currency_field || 'currency_id';
    var currencyID = this.record.data[currencyField] && this.record.data[currencyField].res_id;
    this.currency = session.get_currency(currencyID);
    this.formatOptions.currency = this.currency;

//-------------------------------------------------------------------
core/session.js

get_currency: function (currency_id) {
    return this.currencies[currency_id];
},

//-------------------------------------------------------------------
service/session.js

odoo.define('web.session', function (require) {
"use strict";

　　var Session = require('web.Session');
　　var modules = odoo._modules;

　　var session = new Session(undefined, undefined, {modules: modules, use_cors: false});
　　session.is_bound = session.session_bind();

　　return session;

});

//-------------------------------------------------------------------
在session_bind()中调用this.session_init()

在this.session_init()中调用this.session_reload()

session_reload: function () {
    var result = _.extend({}, window.odoo.session_info);
    delete result.session_id;
    _.extend(this, result);
    return $.when();
}

在运行到session_reload时session_info中已经拿到了res_currency的币种信息

wfk！！！
再往底层就搞不明时什么意思了：
window.odoo是什么玩意？
window 又是什么？

interface Window extends EventTarget, WindowTimers, WindowSessionStorage, WindowLocalStorage, WindowConsole, GlobalEventHandlers, IDBEnvironment, WindowBase64, GlobalFetch, WindowOrWorkerGlobalScope, WindowEventHandlers {
