Question

我在下面有一个原始的postgresql查询：

SELECT DISTINCT ON (c.id)
a.first_name as name, b.slug as slug, b.name as property_name, 
d.building_area as building_area, e.address as address

FROM   developers c
JOIN properties b USING (id)
JOIN users a USING (id)
JOIN forms f USING (id)
JOIN property_types d USING (id)
JOIN property_items e USING (id)
WHERE b.developer_id = ".$developer['id']."
AND b.created_at >= '01-01-2017' AND b.created_at <= '01-01-2018'
ORDER  BY c.id, b.name, a.id, a.first_name
LIMIT 5

如何将其更改为Laravel eloquent？我想在执行查询后使用mutator函数来更改响应数据。

我试过这样的话：

$z = Developer::select(DB::raw('
DISTINCT ON (c.id)
a.first_name as name, b.slug as slug, b.name as property_name, 
d.building_area as building_area, e.address as address
            '))
->join(DB::raw('JOIN properties b USING (id)'))
->join(DB::raw('JOIN users a USING (id)'))
->join(DB::raw('JOIN forms f USING (id)'))
->join(DB::raw('JOIN property_types d USING (id)'))
->join(DB::raw('JOIN property_items e USING (id)'))
->get();

但是拉拉维尔说：

缺少Illuminate \ Database \ Query \ Builder :: join（），
的参数2

有什么想法吗？

任何帮助将不胜感激：D

谢谢
