Rails query timestamp between two hours

Question

I have a problem in Ruby on Rails, where I need to allow a user to set a two time columns, and then query all instances of that model that have the current time within the h

Answer 1

Something like this should work (assuming MySQL):

Model.where("TIME(created_at) BETWEEN '07:00:00' AND '09:00:00'")

You can convert a Time instance to this format with:

Time.now.strftime("%T") #=> "23:02:25"

If the start time is larger than the end time you could reverse the logic, so instead of:

Model.where("TIME(created_at) BETWEEN '23:00:00' AND '01:59:59'")

You could use:

Model.where("TIME(created_at) NOT BETWEEN '02:00:00' AND '22:59:59'")
