Question

我是Yii的初学者，我使用GII创建了一个CURD表。一切正常，但我只想通过放置一个where子句（例如“客户性别为男性）从数据库中获取某些记录。我无法在Gii生成的代码中找到从数据库中获取数据的位置以及我需要的位置在代码中插入WHERE子句。

如您所知，Gii生成了模型，控制器和视图文件。模型文件如下。我的视图使用CGridView生成CRUD表。

    public static function model($className = __CLASS__) {
    return parent::model($className);
}

/**
 * @return string the associated database table name
 */
public function tableName() {
    return 'test_prefixtbl_client_local';
}

/**
 * @return array validation rules for model attributes.
 */
public function rules() {
    // NOTE: you should only define rules for those attributes that
    // will receive user inputs.
    return array(
        array('client_id', 'required'),
        array('client_id', 'length', 'max' => 15),
        array('surname, forename', 'length', 'max' => 20),
        array('title', 'length', 'max' => 6),
        array('status', 'length', 'max' => 8),
        array('dob', 'safe'),
        // The following rule is used by search().
        // Please remove those attributes that should not be searched.
        array('client_id, surname, forename, title, status, dob', 'safe', 'on' => 'search'),
    );
}

/**
 * @return array relational rules.
 */
public function relations() {
    // NOTE: you may need to adjust the relation name and the related
    // class name for the relations automatically generated below.
    return array(
    );
}

/**
 * @return array customized attribute labels (name=>label)
 */
public function attributeLabels() {
    return array(
        'client_id' => 'Client ID',
        'surname' => 'Surname',
        'forename' => 'Forename',
        'title' => 'Title',
        'status' => 'Status',
        'dob' => 'Date of birth (yyyy-mm-dd)',
        'actions' => 'Actions',
    );
}

/**
 * Retrieves a list of models based on the current search/filter conditions.
 * @return CActiveDataProvider the data provider that can return the models based on the search/filter conditions.
 */
public function search() {
    // Warning: Please modify the following code to remove attributes that
    // should not be searched.

    $criteria = new CDbCriteria;

    $criteria->compare('client_id', $this->client_id, true);
    $criteria->compare('surname', $this->surname, true);
    $criteria->compare('forename', $this->forename, true);
    $criteria->compare('title', $this->title, true);
    $criteria->compare('status', $this->status, true);
    $criteria->compare('dob', $this->dob, true);

    return new CActiveDataProvider($this, array(
                'criteria' => $criteria,
                'sort' => array(
                    'defaultOrder' => 'dob DESC',
                ),
            ));
}

您有两种方法可以进行查询，一种使用查询构建器（tutorial here），如下所示：

$clientLocalArray = Yii::app()->db->createCommand()
->select()
->from("test_prefixtbl_client_local")
->where("gender = :gender", array(":gender"=>$gender))
->queryAll();

或者您可以使用Active Record本身（tutorial here），如下所示：

$clientLocalArrayObjects = ClientLocal::model()->findAllByAttributes(array(
"gender" => $gender
));

有任何疑问，请问！：）

添加Gii生成CRUD的地方
