如何查詢字段並返回Projex Orb的數據集？

Question

我試圖找到所有reasons對象與type_id = 3：

用ActiveRecord，我希望查詢爲：

reasons = Reason.where('type_id = 3') 

那麼我可以遍歷每個原因有：

reasons.each do |reason| 
    # do stuff with the reason... 
end 

Answer 1

對於更簡單的查詢，可以使用支持縮短語法的新過濾器選項：

reasons = Reason.all().filter(type_id=3) 
for reason in reasons: 
    # do stuff with reason 

對於更高級的查詢，您可以使用查詢語法：

from orb import Query as Q 
reasons = Reason.select(where=Q('type_id') == 3) 
for reason in reasons: 
    # do stuff with reason
