Rails Cheat Sheet

This is a living doc. with my notes on getting off the ground and surviving around a Rails apps. My experience with Rails is rather clunky & hardly anything to speak of Ruby.

Set up
Ubuntu OS, Rails 2.0, Ruby 1.8 running on Mongrel behind an Apache web server

Books
A good starting point would be "Four Days on Rails" by John McCreesh.

Installing on Ubuntu:

- Install the following through Synaptic
Ruby 1.8
Gem 1.8
mysql client/ server (should be installed to connect & run mysql server locally)

- Further install all essential gems (you can go about this lazily, installing what you need):
sudo gem install -v=2.0.2 rails

Gems installed on my dev:
gem list 
    actionmailer (2.1.0, 2.0.2)
    actionpack (2.1.0, 2.0.2)
    activerecord (2.1.0, 2.0.2)
    activeresource (2.1.0, 2.0.2)
    activesupport (2.1.0, 2.0.2)
    cgi_multipart_eof_fix (2.5.0)
    daemons (1.0.10)
    fastthread (1.0.1)
    gem_plugin (0.2.3)
    localization_generator (1.0.8)
    mongrel (1.1.5)
    mongrel_cluster (1.0.5)
    mysql (2.7)
    rails (2.0.2)
    rake (0.8.1)
    salted_login_generator (2.0.2)


Creating your first app
    rails <Application Name>
    edit config/database.yml for correct database settings
    ./script/generate model <modelName>
    ./script/generate controller <controllerName>
    edit db/migrate/<record name> for the appropriate insert and delete scripts
    rake db:migrate
    rake db:migrate RAILS_ENV=production
    Scaffold the controller (put the text active_scaffold : <modelName>

Starting the server
  Within the project folder type:
 ./script/server

Hit http://localhost:9000/ to test. Monitor the console outputs for any issues. Once you find things are working, you can turn this into a daemon (adding & to the script).
./script/server --env=production &
