ActiveRecord查询语法

Question

@past_topics = Topic.includes(:user, :event).where("event_id IS NOT NULL "cached_votes_up DESC").page(params[:page]).per(6)

这是我的代码。

如何在event.date < DateTime.now条件下将where添加到此代码？

Answer 1

只需追加它：）

@past_topics = ... # your code
@past_topics = @past_topics.where('events.date < ?', DateTime.now)
