Rails 3 DateTime Comparison w/ Date In An ActiveRecord Query

Question

I\'m trying to search a model for any dates equal to a specific date while omitting the timestamp. In Rails I could simply execute this as DateTime.to_date == somedate

Answer 1

DateTime class have two usefull methods to do this: beginning_of_day and end_of_day.

For this case, in which you have a Date object, you might do:

Foo.where('created_at >= #{Date.today.to_time.beginning_of_day} AND 
           created_at <= #{Date.today.to_time.end_of_day}')

Notice that you have to transform the Date object to a DateTime object
