I wrote in my user model :

  def validate     errors.add(:born_on, "is invalid") if Proc.new { |user| DateTime.parse(user.born_on) }    end

it's wrong I know, running in the console raises an ArgumentError

Loading development environment (Rails 2.3.2)

born_on = "99/99/9999"

=> "99/99/9999"

DateTime.parse(born_on)

ArgumentError: invalid date   from /usr/local/lib/ruby/1.8/date.rb:1573:in `new_by_frags'   from /usr/local/lib/ruby/1.8/date.rb:1618:in `parse'   from (irb):2

how can I write my validation Proc ?

thanks for your help

I wrote in my user model :

def validate

errors.add(:born_on, "is invalid") if Proc.new { |user|

DateTime.parse(user.born_on) }

end

Try out this

def validate DateTime.parse(self.born_on)

 rescue  
errors.add(:born_on, "is invalid")

end

it’s wrong I know, running in the console raises an ArgumentError

born_on = “99/99/9999”

=> “99/99/9999”

DateTime.parse(born_on)
