javascript - ExtJs：控制台在测试版本中返回无法识别的别名：data.validator.presence

Question

在运行应用程序构建测试并运行测试构建后，我正在使用 extjs 6.2 制作应用程序，控制台返回错误：

未捕获的错误：[Ext.createByAlias] 无法识别的别名：data.validator.presence

我知道这与我的登录页面的模型有关，但我不确定如何解决这个问题。

登录页面：

登录控制器

登录验证模型

Ext.define('uber.model.User',{

    fields: [

        { name: 'username', type: 'string' },

    ],

    validators: {
        username: { type: 'presence', message: 'please input valid username' },
        password: { type: 'presence', message: 'please input valid password' }
    }
