基于 yiisoft/yii2-app-advanced,在 GitHub 上新建仓库 yii2-app-advanced,新建接口应用(实现 RESTful 风格的 Web Service 服务的 API),实现模型分层:数据层、逻辑层,明确公共目录、应用、模块的继承、引用关系 (二)

1、定义与规范:
定义:
(1)数据层:models 用于定义数据相关的自动验证和自动完成和数据存取接口;
(2)逻辑层:logics 用于定义数据相关的业务逻辑;

规范:
(1)/common/models 目录中的模型类文件仅允许Gii工具所生成,为公共的模型数据层;
(2)/common/logics 目录中的模型类文件为业务逻辑相关,继承至 /common/models 数据层,为公共的模型逻辑层;
(3)/common 目录中需要引用模型类文件,仅引用 /common/logics 中的模型类文件,例:

public $modelClass = 'common/logics/User';

(4)/api/models、/backend/models、/frontend/models 目录中的模型类文件为业务逻辑相关(仅与各应用相关),继承至 /common/logics 公共逻辑层;
(5)接口、前端、后端应用目录中需要引用模型类文件,仅引用各自目录下的对应模型类文件,例:

use api/models/User;

(6)/api/modules/v1/models 目录中的模型类文件为业务逻辑相关(仅与模块相关),继承至 /api/models 应用逻辑层;
(7)模块目录中需要引用模型类文件,仅引用各自模块下的对应模型类文件,例:

public $modelClass = 'api/modules/v1/models/User';

2、在common目录中新建logics目录,用于MySQL模型的逻辑层所在目录,如图1

3、复制 /common/models/LoginForm.php、/common/models/User.php 至 /common/logics,如图2

复制 /common/models/LoginForm.php、/common/models/User.php 至 /common/logics

图2

4、在common/models目录中的MySQL模型文件仅为Gii工具所生成,删除 /common/models/LoginForm.php,如图3

在common/models目录中的MySQL模型文件仅为Gii工具所生成,删除 /common/models/LoginForm.php

5、配置路由,使用美观的 URL ,编辑 /frontend/config/main.php

        'urlManager' => [
            'enablePrettyUrl' => true,
            'showScriptName' => false,
            'rules' => [
            ],
        ],

6、国际化的支持,新建目录 /common/messages/en-US/model、/common/messages/zh-CN/model,分别用于模型的数据层的美国英语、中文简体;新建 /common/messages/{language}/app.php、/common/messages/{language}/error.php、/common/messages/{language}/success.php,分别用于应用全局消息、应用错误消息、应用成功消息,如图4

app.php

<?php
return [
];

error.php

<?php
return [
    20000 => 'error',
];

success.php

<?php
return [
    10000 => 'success',
];

7、配置应用程序语言,源语言为美国英语,目标语言为简体中文,当源语言和目标语言相同时,是否强制进行消息翻译,默认为假,设置为真,编辑 /common/config/main.php

    'sourceLanguage' => 'en-US',
    'language' => 'zh-CN',
    'components' => [
        'i18n' => [
            'translations' => [
                '*' => [
                    'class' => 'yii/i18n/PhpMessageSource',
                    'forceTranslation' => true,
                    'basePath'=>'@common/messages',
                    'fileMap' => [
                        'app' => 'app.php',
                        'error' => 'error.php',
                        'success' => 'success.php',
                    ],
                ],
            ],
        ],
        'cache' => [
            'class' => 'yii/caching/FileCache',
        ],
    ],

8、打开网址:http://www.github-shuijingwan-yii2-app-advanced.localhost/gii/model ,选项,命名空间为common/models,此时需支持国际化,覆盖/common/models/User.php,如图5
