I didn’t try this version yet but just today I’ve decided to begin my new rails project with the new one. There are already lot of resources out there on the web. The screencast are always extremely usefull, I do suggest every developers to put an eye on them.

My doubt since now was, as for every new release, the compatibility with the most common plugins I use in my projects. This is the big question: are my plugins ready for Rails 3.0? Fortunately, thanks to Rails Plugins Compatibility website, I could checked that lot of plugs are 3.0 ready and for that I feel ready to begin!

So happy I can use JQuery as I did wish since many time! A big thanks to Prototype and Scriptacolous that served me so well in these years!

So, let’s try it!

Aptana Studio is fully installed on my laptop but, when I try to install the RedRails plugin, it returns this error:

Requested operation cannot be performed because it would invalidate the current configuration. See details for more information.

Ruby Mylyn Connector Feature (Optional) (0.9.3.6479) requires feature
"org.eclipse.mylyn.context_feature (2.0.0.v20070628-1000)", or later version.

The solution: http://support.aptana.com/issues/browse/ROR-156

The most important steps are:

1. Went to Help=>Updates=>Find and Install. Installed three Eclipse updates that the system found. Installation of updates worked ok.
2. When the update window appears with RadRails updates, expand the tree and uncheck the box next to the Ruby Mylyn Connector Feature. This is an optional extension for users of Mylyn. You don’t need it, so you can safely uncheck the box and install.

This seems to works either on Windows, Osx and Linux

Oggi il mio primo esperimento con SQLite su un progetto rails. Va oremesso che spulciando documentazione ho visto che SQLite sarà integrato come database di default per rails mettendo mysql come scelta opzionale.
Per prima cosa è necessario installare la gemma sqlite3

 sudo gem install sqlite3-ruby

Poi si deve configurare il proprio file database.yml

development:

  adapter: sqlite3

  dbfile: dev.db

test:

  adapter: sqlite

  dbfile: test.db

production:

  adapter: sqlite

  dbfile: prod.db

A questo punto basta sotto lib/task/ un rake db.rake tipo questo:

namespace :db do

  desc 'Inserire i dati default'

  task :install => [:environment, 'db:migrate'] do |t|

    sDbPath = "#{ ENV['RAILS_ROOT'] }/db"

    h = YAML.load_file("#{ ENV['RAILS_ROOT'] }/config/database.yml")

    hConnection = h[ENV['RAILS_ENV']]

     puts "-----"

     puts "eseguo sqlite3 ..."

    `sqlite3 -echo '#{ sDbPath }/#{ hConnection['dbfile'] }' < '#{ sDbPath }/i_miei_dati.sql'`

  end

end

Semplice, efficace, veloce!
