在活动记录/ arel数据库不可知的方式中编写以下sql

Question

I got the following sql expression

g.date > CURRENT_DATE + INTERVAL '1' day * t.notice_days

it works on postgres and as raw sql via my app, Is there an elegant Active Record / AREL way to write the same expression?

Answer 1

Assuming you can get the Integer version of t.notice_days and G is a model you should just be able to do:

future_time = t.notice_days.days.from_now
g.where("data > ?", future_time)

also you can set future_time as Time.now + t.notice_days.days
