Rails where date is greater than given date query

问题

Trying to search where movies coming out have a release date greater than today's date

 Movie.where('release > ?', Date.today)
ActiveRecord::StatementInvalid: Mysql::ParseError: You have an error in your SQL     syntax;    check the manual that corresponds to your MySQL server version for the right syntax to use near 'release > '2011-09-25')' at line 1: SELECT `movies`.* FROM `movies` WHERE (release > '2011-09-25')

回答1:

Rails 3+ :

Movie.where('release > ?', DateTime.now)

---

Pre Rails 3

Movie.where(['release > ?', DateTime.now])
