How to specify a less than today condition on a date in Rails ActiveRecord

I'm trying to figure out how to pull all the records in my set where their fields publish is true and expires is less than today. I have the following but I don't think the less than part is working, can someone please point me on the right track?

Announcement.where(publish: true, :expires < Date.today)

Thanks in advance for your help
