Check this code:
class Client < ActiveRecord::Base
validates_presence_of :name, :itin, :address
validates_uniqueness_of :itin
has_many :invoices, :dependent => :protect
def initialize(attrs = {}, &block)
super
self.active ||= true
end
end
class ClientController < ApplicationController
active_scaffold :client do |config|
config.label = "Clientes"
config.columns = [:name, :itin, :address, :active, :invoices]
config.update.columns = config.create.columns =
[:name, :itin, :address, :active]
columns[:name].label = "Nombre"
columns[:itin].label = "NIT"
columns[:address].label = "Dirección"
columns[:active].label = "Activo"
columns[:invoices].label = "Facturas"
config.print_pdf.header_text = "Lista de clientes"
end
def destroy
begin
super
rescue ActiveRecord::ReferentialIntegrityProtectionError
send_flash('Imposible borrar porque hay registros relacionados')
end
end
end
