Flash Messages, System Messages, Ruby on Rails, by style, debug and test

controller:

flash[:notice] = "Correct things."
flash[:error]  = "Alert things."
flash[:debug]  = "Simple debug."

views/layouts:

<%- flash.each do |name, msg| -%>
  <%= content_tag :div, msg, :id => "flash_#{name}" %>
<%- end -%>

css out of dev, in test, this can help you in both environments:

#debug{
  display:none;
}

ruby on rails i18n

An approach:

$script/plugin install git://github.com/svenfuchs/rails-i18n.git

$cp config/locales/en.yml config/locales/es-ar.yml

config/environment.rb

  config.time_zone = 'Buenos Aires'
  config.i18n.default_locale = :"es-ar"

app/views/payment_operation/show.html.erb

<%= t('views.payment.show_title', :count => @foo.size, :bar => @foo.name) %>

config/locales/es-ar.yml

es-ar:
    views:
      payment:
        show_title: 
          zero: "Mostrando operación de pago y {{bar}}."
          one: "Mostrando operación de pago y {{bar}}."
          many: "Mostrando operación de pago y {{bar}}."

Ruby on Rails, model, validate alphanumeric and space characters

class Product < ActiveRecord::Base
...
  validates_format_of :name, :with => /^([[:alpha:]]|[[:blank:]])+$/

Survive in php.. a logger method.

function logger($msg){
 if(!isset($GLOBALS['logger'])){
  $GLOBALS['logger'] = fopen("/var/www/apps/logs/dev.log","a");
 }
 fwrite($GLOBALS['logger'],"$msg\n");
}

function request($id = ''){
  logger("dir/file.php::request(id[".$id."])");
...
}
