time textfield validation (hh:mm)

rubyonrails-talk

I am trying to find the best way in validating a textfield 'start_time' in a form, based on the expected strftime format ("%I:%M%p")

if a user don't enter the correct format like " 01:45PM" hh:mm in 12-hours (with PM/AM ) then should raise an error I know it's possible to validate using gsub , but I wonder if there is any possibility to raise an ArgumentError in parsing the value in a Date/Time function...

I tried

start_time = "89" t = Time.parse(Time.now.to_date.to_s + "," + start_time) but it doesn't raise an error...

Hi

You need not bother about date/time validations. There is plugin called validates_date. just download & install it. in your model, add following line and you are done.

validates_date :field_name
