在這添加另一種排序功能，即
1、創建子類繼承\yii\db\ActiveRecord類， 並重寫attributes()函數，之後所有的model類全部繼承自定義的ActiveRecord類
/**
* 關聯表屬性，判定哪些關聯表字段需要排序
* @var unknown
*/
static $relationAttributes = ['customer_name' => 'table.name'];
public function attributes(){
$attributes = parent::attributes();
if(static::$relationAttributes){
foreach (static::$relationAttributes as $key => $attribute){
if(is_number($key){
$attributes[] = $attribute;
}else{
$attributes[$key] = $attribute;
}
}
}
return $attributes;
}
2、創建\yii\data\ActiveDataProvider子類
在構造函數中添加
$modelClass = $config['query']->modelClass;
$model = new $modelClass();
$sortAttributes = [];
foreach ($model->attributes() as $key => $attribute) {
if(is_numeric($key)){
$sortAttributes[$attribute] = [
'asc' => [$attribute => SORT_ASC],
'desc' => [$attribute => SORT_DESC],
'label' => $model->getAttributeLabel($attribute),
];
}else{
$sortAttributes[$key] = [
'asc' => [$attribute => SORT_ASC],
'desc' => [$attribute => SORT_DESC],
'label' => $model->getAttributeLabel($attribute),
];
}
}
$config['sort']['attributes'] = $sortAttributes;
parent::__construct($config);通過上述設置，就是讓顯示的字段和數據庫字段做一個映射，也就不用在search()函數中設置setSort。
2、不寫label
public function attributeLabels(){
return [
...........
'customer_name'=>'自定義名',
......
];
}
這樣就不用到處添加label屬性了
