Change default table name of session active_record_store for rails 2.3.x.

murad — Mon, 19 Oct 2009 20:55:45 +0000

Just a little tip that can save some time. Before rails 2.3.x you should define the new table name like

CGI::Session::ActiveRecordStore::Session.set_table_name “new_table_name”

Now you have to define it like that

ActiveRecord::SessionStore::Session.set_table_name “new_table_name”

Off-Topic - LinkedIn import contacts.

murad — Thu, 20 Aug 2009 20:19:15 +0000

Hoje resolvi me cadastrar no LinkedIn, logo que o cadastro é realizado, o sistema pergunta se quer importar contatos de alguns lugares, incluindo sua lista de contatos do gmail. Normalmente acho esta opção uma mão na roda. Sendo assim, aceitei importar a lista de contatos do gmail. Abaixo está a tela do sistema neste ponto e meu entendimento quanto a utilização da mesma.

Na caixa grande do lado esquerdo estão todos os contatos do meu gmail, na caixa pequena do lado direito, segundo a seta verde, o link remove all e o botão Invite, estariam os usuário que seriam convidados. Sendo assim, cliquei no botão Invite e todos os meus contatos receberam um convite!!! Depois de alguns minutos, pela quantidade de emails que recebi de confirmação e mensagens instantâneas de pessoas perguntando do que se tratava o convite, tive certeza que convidei todos os meus contatos para o LinkedIn. Por todos, entende-se amigos, clientes, grupos de email que participo, namoradas, ex-namoradas, cachorros, periquitos e papagaios! Legal né? Só no trabalho houveram pessoas que receberam 6 emails de convite.

Peço desculpas a todos que receberam o convite indevidamente!

Gitorious installation.

murad — Mon, 20 Apr 2009 18:26:29 +0000

I just create a script that will automatically install gitorious in a ubuntu server.

If you are having troubles installing it, you can try the script or take a look in what it does.

Customise error fields

murad — Sun, 22 Mar 2009 22:46:07 +0000

The default rails error message style is to insert a div with attribute class set to fieldWithErrors involving the form field.

That is how I’ve changed the default rails behaviour to inject css error class into the object.

sudo apt-get install php5-ldap;
Download LdapAuthentication.php and copy it to extensions directory;
edit LocalSettings.php

#LDAP Auth
require_once ‘extensions/LdapAuthentication.php’;

$wgAuth = new LdapAuthenticationPlugin();
$wgLDAPDomainNames = array(’{#DOMAINNAME#}’);
$wgLDAPServerNames = array(’{#DOMAINNAME#}’ => ‘{#domain_server_host#}’);
$wgLDAPSearchStrings = array(’{#DOMAINNAME#}’ => ‘{#DOMAINNAME#}\\USER-NAME’);
$wgLDAPEncryptionType = array(’{#DOMAINNAME#}’ => ‘clear’);
$wgLDAPUseLocal = false;
$wgMinimalPasswordLength = 1;
$wgLDAPBaseDNs = array(’{#DOMAINNAME#}’ => ‘{#BASEDN#}’);
$wgLDAPSearchAttributes = array(’{#DOMAINNAME#}’ => ’sAMAccountName’);

Restart apache and test it.

How to use gem ruby_plsql with JRuby

murad — Sat, 04 Oct 2008 16:09:40 +0000

That is just the basic configuration. Hope that helps.

enviroment.rb

config.gem “ruby-plsql”, :lib => “ruby_plsql”

models/some_model.rb

require “ruby_plsql”

class SomeModel < ActiveRecord::Base

def persist

plsql.connection = ActiveRecord::Base.connection.

raw_connection.connection

appraisal_id = plsql.bra_customhr_eval_pk.create_appraisal(
:p_employee_number => self.appraisee.employee_number,
:p_appraisal_template_id => @avalTemplate[0].template_id,
:p_period_start_date => @avalTemplate[0].valid_from,
:p_period_end_date => @avalTemplate[0].valid_until,
:p_business_group_id => self.appraisee.business_group_id,

:p_appraisal_id => nil,
:p_object_version_number => nil)[:p_appraisal_id

end

JRuby + JNDI + JBOSS + Oracle

murad — Fri, 18 Jul 2008 15:22:06 +0000

I finally got jndi with jboos to work in jruby on rails . Bellow is an example of files configuration.

I was getting the bellow error:

javax.naming.NamingException has no valid JNDI binding

=====oracle-ds.xml=====

simu3
jdbc:oracle:thin:@xxx.xxx.xxx.xxx:1521:simu3
oracle.jdbc.driver.OracleDriver
login
password
5
20
5000
15
5

=====warble.rb=====
have to enable the line in warble.rb like this:
# Additional files/directories to include, above those in config.dirs
config.includes = FileList["jboss-web.xml"]

# JNDI data source name
config.webxml.jndi = “jdbc/simu3″

=====database.yml=====
production:
adapter: jdbc
jndi: “java:/simu3″
driver: oracle.jdbc.driver.OracleDriver

=====jboss-web.xml=====

jdbc/simu3
java:/simu3

The most important thing was the creation of jboss-web.xml
