• 默认控制器

  1. 普通控制器

     defaultController => 'site'
     

  2. module内的默认控制器

     modules => array(
         'web' => array(
             'class' => 'application.modules.web.WebModule',
             'defaultController' => 'index'
         )
     )
     

  3. 默认控制器为module内的控制器

     defaultController => 'web/site'
     

• 别名

  1. 内置别名有

     Yii::setPathOfAlias('application',$this->getBasePath());
     Yii::setPathOfAlias('webroot',dirname($_SERVER['SCRIPT_FILENAME']));
     Yii::setPathOfAlias('ext',$this->getBasePath().DIRECTORY_SEPARATOR.'extensions');
     

  2. 获取别名的路径

     Yii::app->getAliasPath('webroot');
     

  3. 自定义别名

     Yii::setPathOfAlias('test',$this->getBasePath());
     

• 路由

  1. 后缀

     'urlSuffix'  => '.html'
     

  2. 忽略大小写

     'caseSensitive' => false,
     

  3. 隐藏module

     '/<controller:\w+>' => 'web/<controller>',
     '/<controller:\w+>/<action:\w+>' => 'web/<controller>/<action>',
     '<controller:\w+>/<action:\w+>/<id:\d+>'=>'web/<controller>/<action>'
     

• 日志

  1、 显示执行的sql

  'routes' => array(
      array(
        'class' => 'CWebLogRoute',
         'levels' => 'trace,warning,error,info',
         'categories' => 'system.db.CDbCommand.*',
     )
  ),
  

  2、自定category调试控制器台程序

  array(
      'class'=>'CFileLogRoute',          
      'categories'=>'debug.*',
  ),
  

  使用

  Yii::log($message, 'info', 'debug');
  

• ActiveRecord

  1. 自动记录 创建时间、修改时间

     protected function beforeSave()
     {
         if ($this->isNewRecord) {
             $this->add_time = time();
         } else {
             $this->modify_time = time();
         }
         return parent::beforeSave();
     }
     

2. 乐观锁(版本号)

        class PostModel extends CActiveRecord
        {
            public function rules()
            {
                return array(
                    array('version', 'required'),
                    array('id', 'exists', 'on' => 'update', 'criteria' => array('condition' => 'version <'. $this->version))
                );
            }
        }

        $model1 = PostModel::model()->findByPk(1);
        $model2 = PostModel::model()->findByPk(1);

        $model1->version = $model->version++;
        $model->save();//true


        $model2->save();//false

• 显示控制器action执行时间

  protected function afterAction($action)
  {
      $time = sprintf('%0.5f', Yii::getLogger()->getExecutionTime());
      $memory = round(memory_get_peak_usage() / (1024 * 1024), 2) . "MB";
  
      echo "Time: $time, memory: $memory";
      parent::afterAction($action);
  }
  

• 维护通知main.php

  return array(
   .... 
       'catchAllRequest'=>array(
            'offline/notice'
            'otherParams'=>'value',
        ),
   ....
  ),
