Hola a todos de la lista…
en mi proyecto quiero que antes de guardar valido el formato de un campo
fecha, esto es lo que tengo
validates_format_of :fecdurcom_at, :message => “^ El Formato del campo
Vigente hasta es Inválido”, :with =>
/\A(^((((0[1-9])|([1-2][0-9])|(3[0-1]))|([1-9]))--)$)\Z/i
yo no se mucho de regular expresion pero eso lo consegui de una pagina:
pero no me funciona no me deja grabar me da error
algun guru de perl que me pueda ayudar?
muchas gracias

Eso es tremendo pollo.
Como es el flujo de entrada de fechas en tu app? En que momento se
pasan de String a Date?
Por otro lado comentarte que por convenio un campo *_at en Rails es un
datetime, las fechas se guardan en campos *_on.

SÃ, tremendo pollo, cuando se puede utilizar a Ruby para ello:
http://apidock.com/ruby/Date/strptime/class
class MiClase
validate :validates_fecdurcom_date_format
private
def validates_fecdurcom_date_format
errors.add(:fecdurcom, “el mensaje”) unless parse_date(fecdurcom)
end
def parse_date(date, formats = [‘%d-%m-%Y’, ‘%d-%m-%y’])
formats.each do |format|
begin
Date.strptime(date, format)
return true
rescue ArgumentError
# nada aquÃ
end
end
return false
end
end
Eso deberÃa funcionar con fechas como las que deberÃa validar tu RegEx.
Suerte

Eso es que le estás pasando un valor nulo al parse_date. DeberÃas
comprobarlo antes de enviarlo:
def validates_fecdurcom_date_format
unless fecdurcom.nil?
errors.add(:fecdurcom, “el mensaje”) unless parse_date(fecdurcom)
end
end
Suerte.
