將常規查詢更改爲Laravel查詢構建器

Question

如何使用Laravel查詢構建器編寫此常規查詢？

SELECT `t1`.`id` , `i`.`item_description` AS `name` , SUM(t1.amount) AS total, `u`.`name` AS `unit` 
FROM `fees9_items` AS `t1` 
LEFT JOIN `items` AS `i` ON `i`.`id` = `t1`.`item_id` 
LEFT JOIN `mesure_units` AS `u` ON `u`.`id` = `i`.`unit` 
LEFT JOIN `fees9` AS `f` ON `f`.`id` = `t1`.`fees9_id` 
WHERE date >= '2016-01-01' AND (f.field1=1 OR f.field2=1 OR f.other =1) 
GROUP BY `i`.`id` 

這部分是非常重要的：

(f.field1=1 OR f.field2=1 OR f.other =1)

嘗試了這一點，它應該工作

$query = DB::table("fees9_items AS t1") 
       ->select(array("t1.id", "i.item_description AS name", 
         DB::raw("SUM(t1.amount) as total"), "u.name AS unit" 
        ) 
       ->leftJoin("items AS i", "i.id", "=", "t1.item_id") 
       ->leftJoin("mesure_units AS u", "u.id", "=", "i.unit") 
       ->leftJoin("fees9 AS f", "f.id", "=", "t1.fees9_id") 
       ->where("date", ">=", "2016-01-01") 
       ->where(function($query){ 
        $query->where("f.field1", "=", 1) 
         ->orWhere("f.field2", "=", 2) 
         ->orWhere("f.other", "=", 1) 
        ) 
       ->groupBy("i.id") 
       ->get();
