yii1.1：umageをアップロードせずにレコードを更新できません

Question

私は別のプログラマーが書いたウェブサイトに対処しようとしていました。ウェブサイトはyiiで構築されています。1.1.4

毎回新しい画像をアップロードせずに「店舗」レコードを更新できないようです。ここに画像をアップロードせずに更新しようとするとメッセージが表示されます： "次の入力エラーを修正してください：

画像は空白にできません。

ピクチャフィールド（別名「アイコン_ファイル名」）も必要ありません。 また、ほとんどのレコードにはまだ画像がアップロードされていません。

誰でも問題が分かりますか？

モデル：：ここ

はコードである

public function rules() { 
    // NOTE: you should only define rules for those attributes that 
    // will receive user inputs. 
    return array(
     array('name, stream_id, full_address,about, country_id', 'required', 'on' => array('create')), 
     array('status, stream_id, lock_version', 'numerical', 'integerOnly' => true), 
     array('name, email', 'length', 'max' => 255), 
     array('about, full_address, website_url', 'length', 'max' => 500), 
     array('website_url, maps_service_url', 'url'), 
     array('phone, fax', 'length', 'max' => 30), 
     array('phone, fax', 'PcSimplePhoneValidator'), 
     array('country_id, region_id, assigned_user, created_by, last_updated_by_user_id', 'length', 'max' => 10), 
     array('assigned_user', 'validateAssignedUser', 'except' => 'search'), 
     array('city_id', 'length', 'max' => 6), 
     array('icon_filename', 'file', 
      'types' => "jpg,jpeg", 
      'wrongType' => Yii::t('StoresModule.forms', "Invalid file type. These are the supported file types: {extensions}"), 
      'maxSize' => 1048576, 
     ), 
     array('icon_filename', 'file', 'allowEmpty' =>true, 'on' => 'update'), 
     array('updated_on', 'safe'), 
     // The following rule is used by search(). 
     // Please remove those attributes that should not be searched. 
     array('id, name, email, stream_id, searchText, status, about, full_address, phone, fax, website_url, country_id, region_id, city_id, icon_filename, assigned_user', 'safe', 'on' => 'search'), 
    );

Answer 1

あなたがDBでのgetInstanceや店舗に異なる属性を使用しなければならないことができますか？

E.G.コントローラ

$model->photo = CUploadedFile::getInstance($model, 'photo'); 

で

public $photo; 

    array('photo', 'file', 'maxSize' => 1048576, 'types' => 'jpg, png, gif, jpeg', 'allowEmpty' => true) 

その後、私はどのように知らない名前、パス、またはどのようなご希望

$model->pictureName = $model->photo->name;
