MongoMapper: finding all documents created on a specified date

I need to write a query that finds all documents created on a specified date.

Let's suppose that the date is today.

I tried this:

Document.all(:created_at => Date.parse(Time.now.strftime('%Y/%m/%d')))

but I got:

Cannot serialize an object of class Date into BSON.

Thanks for your help.

UPDATE This link explains how to do so Date Range Queries With MongoMapper.

Document.count( :created_at => { '$gt' => 2.days.ago.midnight, '$lt' => 1.day.ago.midnight } )
