您可以在 Rails 3 搜索中对日期进行大于比较吗? [英] Can you do greater than comparison on a date in a Rails 3 search?

问题描述

我在 Rails 3 中有这个搜索:

I have this search in Rails 3:

Note.where(:user_id => current_user.id, :notetype => p[:note_type], :date => p[:date]).order('date ASC, created_at ASC')

但我需要 :date =>p[:date] 条件等价于 :date >p[:日期].我怎样才能做到这一点?感谢阅读.

But I need the :date => p[:date] condition to be equivilent to :date > p[:date]. How can I do this? Thanks for reading.

推荐答案

Note.
  where(:user_id => current_user.id, :notetype => p[:note_type]).
  where("date > ?", p[:date]).
  order('date ASC, created_at ASC')

或者您也可以将所有内容转换为 SQL 表示法

or you can also convert everything into the SQL notation

Note.
  where("user_id = ? AND notetype = ? AND date > ?", current_user.id, p[:note_type], p[:date]).
  order('date ASC, created_at ASC')
