Question

我在浏览模型中某些自定义规则生成的邮件时遇到问题。

在模型中：

public function rules()
    {
        // NOTE: you should only define rules for those attributes that
        // will receive user inputs.
        return array(
            array('active_yn', 'numerical', 'integerOnly'=>true),
            array('user_name', 'length', 'max'=>20),
            array('password', 'length', 'max'=>100),
            array('full_name', 'length', 'max'=>150),
            // The following rule is used by search().
            // Please remove those attributes that should not be searched.
            array('user_id, user_name, full_name, active_yn', 'safe', 'on'=>'search'),
            array('user_name', 'unique', 'on'=>'api_save, insert', 'message'=>'User already in system'),
            array('user_name, full_name', 'required', 'on'=>'api_save', 'message'=>'Required field, {attribute}, is missing'),
        );
    }

并在我的控制器中。这是一个REST接口..

public function actioncreate(){
        $user = new User();
        $user->scenario = 'api_save';

        // Try to assign POST values to attributes
        if(isset($_POST)){
            foreach($_POST as $key=>$value) {
                // Does the model have this attribute? If not raise an error
                if($user->hasAttribute($key)){
                    $user->$key = $value;
                }else{
                    $var = array('status'=>500,'body'=>'Parameter <b>'.$key.'</b> is not allowed for model');
                    $send = new sendResponse($var);
                }
            }
        }else{
            $var = array('status'=>500,'body'=>'Parameters required for creation');
            $send = new sendResponse($var);
        }
        if(!$user->validate()){
            $str .= $user->message;
            $var = array('status'=>500,'body'=>$str);
            $send = new sendResponse($var);
        }
        $user->save();
        $var = array('status'=>200,'body'=>CJSON::encode($user));
        $send = new sendResponse($var);
    }

如果模型未验证，我想显示模型中的消息。我已经尝试了getError和getErrors，但我收到一条错误，说明_error未定义。

感谢您对这个简单问题的帮助。

经过一番搜索，我找到了答案：

   if($user->save() === false){
        $str = '';
        foreach ($user->errors as $value) {
            $str .= $value[0]."; ";
        }
        $var = array('status'=>500,'body'=>$str);
        $send = new sendResponse($var);
    }else{
        $var = array('status'=>200,'body'=>CJSON::encode($user));
        $send = new sendResponse($var);
    }

我跳过了验证步骤并刚刚保存了模型。如果它返回false，则我可以将$user->errors作为数组或错误消息提取

显示模型验证规则的消息
