random code and what not

Some notes - Ubuntu install rails 3 environment

Had this on my desktop, notes to set up Ubuntu install rails 3 environment

Ubuntu install rails 3 environment

1) Get RVM installed with ruby 1.9.2

2) Install Rails 3 gem
- gem install rails --no-rdoc --no-ri
- .... Successfully installed rails-3.0.5 ... 23 gems installed

3) Install redcar 'ruby ide'
- check out
- for my situation I am only installing it on ruby 1.9.2, if you plan to run multiple versions of ruby this probably will not work when you have your rvm switched to another version
- gem install redcar --no-rdoc --no-ri
- redcar install
- now you should be able to type redcar at the terminal to launch the gui
- lets make a desktop shortcut
- right click on the desktop : Create Launcher
- Type: Application
- Name: Redcar
- Command: /home/YOUR_USER_NAME/.rvm/gems/ruby-1.9.2-head/gems/redcar-0.11/bin/redcar
- Comment: Ruby IDE
- need a tight icon for our launcher
- right click > Properties > click the emblem icon
- Path: /home/YOUR_USER_NAME/.rvm/gems/ruby-1.9.2-head/gems/redcar-0.11/share/icons/redcar-icon-beta.png
- drag the desktop icon up to the launcher bar if you want one there as well
- need to set the icon path again for that one

4) Create a rails application
- mkdir projects; cd projects
- rails new sample_app_01; cd sample_app_01
- in redcar > File > Open Directory > projects/sample_app_01
- ctrl+T > type Gem > open Gemfile
- verify line : gem 'sqlite3'
- back to the terminal
- bundle
- rails g scaffold post title:string body:text
- rake db:migrate
- rails s
- in a browser go to http://localhost:3000/posts
