Ruby Development Guide

By default, teracy-dev already has Ruby installed for the default base box.

Verify that ruby works

$ vagrant ssh
$ ruby --version

And you should see something like this:

ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]

Congratulations, you can do all Ruby related stuff now!

Ruby on Rails (RoR) Development

This guide is based on: http://rubyonrails.org/download/

As Ruby is already installed along with rbenv, you could start using Ruby right away.

  1. Install Rails

    $ vagrant ssh
$ gem install rails
$ rbenv rehash

    Note

    rehash is required by rbenv

  2. Verify Rails

    $ rails --version
Rails 4.2.1

  3. Create a new RoR app

    $ ws
$ cd personal
$ rails new rails-app
$ cd rails-app
$ rails server -b 0.0.0.0

    Tip

    -b 0.0.0.0 here is to make Rails app accept requests from any ip addresses. Required for Vagrant box with forward ports.

    And you should see the output like:

    Warning: You're using Rubygems 1.8.23 with Spring. Upgrade to at least Rubygems 2.1.0 and run `gem pristine --all` for better startup performance.
=> Booting WEBrick
=> Rails 4.2.1 application starting in development on http://0.0.0.0:3000
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server
[2015-03-20 09:14:58] INFO  WEBrick 1.3.1

[2015-03-20 09:14:58] INFO  WEBrick::HTTPServer#start: pid=15258 port=3000

    Open the browser at http://localhost:3000 and you should see Welcome aboard default page. We’re ready for RoR development by following http://rubyonrails.org/documentation/

  4. Use Ruby 2.2.1 instead of default Ruby 1.9.3

    By default, Ruby 1.9.3 is used, however, it’s very easy to use different versions of Ruby thanks to rbenv. We’re going to use Ruby 2.2.1 for RoR development.

    $ ws
$ cd personal
$ rbenv install 2.2.1
$ rbenv local 2.2.1
$ gem install rails
$ rbenv rehash
$ rails new rails-app2
$ cd rails-app2
$ rails server -b 0.0.0.0

    Tip

    Create .ruby-version file with content 2.2.1 within rails-app2 directory to use the right ruby version when cd to that directory.

    Todo

    We’ll support multiple Ruby versions via config by this issue: https://issues.teracy.org/browse/DEV-199

  5. Databases

Sinatra Development

This guide is based on: http://www.sinatrarb.com/

  1. Create Sinatra web app

    Create web app directory:

    $ ws
$ cd personal
$ mkdir sinatra-app
$ cd sinatra-app

    And then create hi.rb file with the following content within sinatra-app directory:

    require 'sinatra'

get '/hi' do
  "Hello World!"
end

set :bind, '0.0.0.0'

    Tip

    set :bind, '0.0.0.0' here is to make Sinatra app accept requests from any ip addresses. Required for Vagrant box with forward ports.

  2. Run the Sinatra web app

    $ gem install sinatra
$ ruby hi.rb

    Now open http://localhost:4567/hi on your browser to see the web app.
