安装

安装此扩展的首选方式是通过 composer。

运行

php composer.phar require --prefer-dist nick-denry/managed-constant-models

或者

"nick-denry/managed-constant-models": "^0.1.0"

将以下内容添加到您的 composer.json 文件的 require 部分。

使用方法

1. 创建管理常量模型

   <?php
   
   namespace app\models;
   
   use nickdenry\managedConstants\interfaces\ManagedConstantInterface;
   use nickdenry\managedConstants\traits\ManagedConstantTrait;
   
   /**
   * TaskStatus constant model
   */
   class TaskStatus implements ManagedConstantInterface
   {
   
       use ManagedConstantTrait;
   
       const ACTIVE = 0;
       const DONE = 1;
       const _ATTRIBUTES = [
           self::ACTIVE => [
               'class' => 'task-active',
               'label' => 'Активна',
           ],
           self::DONE => [
               'class' => 'task-done',
               'label' => 'Завершена',
           ],
       ];
   
   }

2. 与您的其他模型类（例如 yii2 模型）一起使用

   <?php
   
   namespace app\models;
   
   use app\models\TaskStatus;
   
   /**
   * This is the model class for table "task".
   *
   * @property int $id
   * @property string $title
   * @property int|null $created_at
   * @property int|null $updated_at
   */
   class Task extends \yii\db\ActiveRecord
   {
       ...
       /**
       * Get task statuses.
       */
       public static function getStatuses()
       {
           return new TaskStatus(); //TaskStatus()::class;
       }
       ...
   
   }

1. 通过代码获取常量

   <?php
   
   $constValue = Task::getStatuses()::ACTIVE; //$constValue = 0;
   
   Task::getStatuses()::ACTIVE; // ACTIVE constant;
   Task::getStatuses()::DONE; // DONE constant;
   Task::getStatuses()::constants(); // Returns array ['ACTIVE' => 0, 'DONE' => 1]
   Task::getStatuses()::values(); // Returns array [0, 1]
   Task::getStatuses()::listAttributes($constValue); // Returns array ['class' => 'task-active', 'label' => 'Активна']
   Task::getStatuses()::attribute($constValue, 'class'); // Returns 'task-active'
   
   Task::getStatuses()::getList(); 
   // Returns [
   //    ['id' => 0, 'class' => 'task-active', 'label' => 'Активна', ]
   //    ['id' => 1, 'class' => 'task-done', 'label' => 'Завершена', ],
   // ]
