如何將此查詢轉(zhuǎn)移到 Eloquent Query builder?我已經(jīng)嘗試過 DB:raw($query) 這似乎不起作用......嘗試使用的是非常需要的 ->paginate(25) 和 ->get()，都不起作用.這里的任何人都可以讓我朝著正確的方向前進(jìn)嗎?
How can I transfer this query to Eloquent Query builder? I tried already DB:raw($query) which seems not to work... Tried is with the much needed ->paginate(25) and with ->get(), all not working. Anyone here can put me in the right direction?
