Php 我在yii中的登录模块没有'；行不通

我正在yii框架中创建登录操作，但我有一个错误，无法修复。以下是错误：

Property "AdminIdentity.user_name" is not defined. `$record=Admin::model()->findByAttributes(array('username'=>$this->user_name));`

这是我的登录模块：

login.php

<?php $form=$this->beginWidget('CActiveForm', array(    
    'id'=>'login_form',
    'enableAjaxValidation'=>false,
    'enableClientValidation' => true));
     ?>     
        <div class="row">
        <?php echo $form->labelEx($model,'username'); ?>
        <?php echo $form->textField($model,'username',array('size'=>60,'maxlength'=>100)); ?>
        <?php echo $form->error($model,'username'); ?>
        </div>

        <div class="row">
            <?php echo $form->labelEx($model,'password'); ?>
            <?php echo $form->passwordField($model,'password',array('size'=>60,'maxlength'=>100)); ?>
            <?php echo $form->error($model,'password'); ?>
        </div>


        <div id="lower">        

        <?php echo $form->Checkbox($model,'rememberMe'); ?> 
        <?php echo $form->labelEx($model,'rememberMe'); ?>

        <input type="submit" value="Login"/>

        </div>

<?php $this->endWidget(); ?>  

LoginForm

            array('username, password', 'required','message'=>'input username requirement'),
            // rememberMe needs to be a boolean
            array('rememberMe', 'boolean'),
            // password needs to be authenticated

    }

                        if(!$this->_identity->authenticate())
                                $this->addError('password','Incorrect username or password.');
                }
        }

    public function login()
    {       
        if($this->_identity===null)
        {

            $this->_identity=new AdminIdentity($this->username,$this->password);

        }
        if($this->_identity->errorCode===UserIdentity::ERROR_NONE)
        {
            $duration=$this->rememberMe ? 3600*24*30 : 0; // 30 days
            Yii::app()->admin->login($this->_identity,$duration);
            return true;
        }
        else
            return false;
    }
}

AdminIdentity

Admin

Model class:

    public function tableName()

    }

    public function rules()
    {

    {
        return parent::model($className);
    }
}

类AdminIdentity扩展了CUserIdentity，在CUserIdentity中定义了两个属性：

$username

$password

所以你要么改变

 $record=Admin::model()->findByAttributes(array('username'=>$this->user_name));

到

或

---

在AdminIdentity类中声明$user\u name。如果选择声明新属性，请确保在构造函数中设置一个值（需要进行更多更改）

declare

user\u name

after

private$\u id是的，它可以工作，但在我的例子中它必须是这样的：$record=Admin:：model（）->findByAttributes（数组（'user_name'=>$this->username）），多谢各位
 $record=Admin::model()->findByAttributes(array('username'=>$this->user_name));

  $record=Admin::model()->findByAttributes(array('username'=>$this->username));
