我从数据库中获得了一些数据。
$searchModel = new InventorySearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
使用复杂算法计算每种产品的收入和成本。之后,使用以下新成本和收入更新$ dataProvider:
foreach ($dataProvider->models as $model) {
$model->cost = 0;
$model->revenue = 0;
$model->profit = 0;
$model->profit_margin = 0;
foreach($calculated_costs as $item)
{
if($model->id == $item['product_id'])
{
$model->cost = $item['total_cost'];
break;
}
}
foreach($calculated_revenue as $rev_item)
{
if($model->id == $rev_item['product_id'])
{
$model->revenue = $rev_item['total_sales'];
break;
}
}
$model->profit = floatval($model->revenue) - floatval($model->cost) ;
if($model->revenue != 0)
{
$model->profit_margin = ( floatval($model->profit) ) / floatval($model->revenue) ;
}
}
我需要在更新dataprovider后按利润对数据提供者进行排序。有没有办法做到这一点?
