Rails模型：SQL或和關鍵字

Question

我使用的軌道，我想請求喜歡的是：

SELECT * FROM events WHERE id = 5 AND 
active = true AND 
(current_state = 0 OR current_state = 1) 

我寫的東西喜歡的是：

Event.where(id:5).where(active:true).or(Event.where(current_state:)).or 
(Event.where(current_state: 1)) 

但是，當我這樣做，我有這個請求：

SELECT * FROM events WHERE id = 5 AND 
active = true AND 
current_state = 0 OR current_state = 1 

我該如何使用括號？

Answer 1

你可以做這樣的事情：

Event.where('WHERE id = ? AND active = ? AND (current_state = ? OR current_state = ?)', 5, true, 0, 1)
