ruby - Active Record - Find records which were created_at before today

I want to get all records where the created_at field is less than today (a date). Is there anything like:

MyTable.find_by_created_at(< 2.days.ago)

Using ActiveRecord the standard way:

MyModel.where("created_at < ?", 2.days.ago)

Using the underlying Arel interface:

MyModel.where(MyModel.arel_table[:created_at].lt(2.days.ago))

Using some thin layer over Arel:

MyModel.where(MyModel[:created_at] < 2.days.ago)

Using squeel:

MyModel.where { created_at < 2.days.ago }
