Witty.ca - Graham's Professional Archives

So, after starting a number of Rails projects, I thought I'd make a quick list of commands and system changes that I use with almost every install.  (I'll also include some common commands at the bottom.)

_$ rails new myapp -d postgresql -T    # use pg, don't install any tests

$ vi Gemfile
Gemfile begin: ^^^^^^^^^^^^^^^^^^^^^^  # you'll need to update the numbers
 source 'http://rubygems.org'

 gem 'rails', '3.1.1'
 gem 'pg', '0.11.0'
 gem 'heroku', '2.11.0'
 gem 'gravatar_image_tag', '1.0.0'
 gem 'will_paginate', '3.0.2'
 gem 'faker', '1.0.1'        # This shouldn't be here, but Heroku errors won't stop!

 gem 'jquery-rails', '1.0.16'
 
 # Gems used only for assets and not required
 # in production environments by default.
 group :assets do
   gem 'sass-rails',   '~> 3.1.4'
   gem 'coffee-rails', '~> 3.1.1'
   gem 'uglifier', '>= 1.0.3'
 end

 group :development do
   gem 'rspec-rails', '2.7.0'
   gem 'annotate', :git => 'git://github.com/ctran/annotate_models.git'
 end
 
 group :test do
   gem 'turn', :require => false    # Pretty printed test output
   gem 'rspec-rails', '2.7.0'
   gem 'webrat', '0.7.3'
   gem 'factory_girl_rails', '1.3.0'
 end
 
 group :production do
   gem 'thin', '1.2.11'
 end
Gemfile end: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


$ bundle install
$ rails generate rspec:install
$ vi .gitignore
.gitignore begin ^^^^^^^^^^^^^^^^^^^^^^^
     .bundle
      log/*.log
      *.log
      /tmp/
      tmp/
      .sass-cache/
      *.swp
      *~
      .project
      .DS_Store
      bin/
      public/assets/
.gitignore end ^^^^^^^^^^^^^^^^^^^^^^^

$ git init
$ git add .
$ git commit -m "Initial commit"
$ vi README
$ git mv README README.markdown
$ git commit -am "Improved README"

(go to GitHub and at your Dashboard create a New Repository)
$ git remote add origin git@github.com:........ (from github)
$ git push origin master

$ bundle install --binstubs

$ heroku keys          // To see what RSA keys are in the system
$ heroku keys:add  // To choose which key to use
$ heroku create myapp --stack cedar
$ git remote rm heroku
$ git remote add heroku git@heroku.com:myapp.git
$ git push heroku master
$ heroku open

Some common commands:

$ git checkout -b first_branch_name
$ rails generate controller Pages home about
$ rails g controller Users new
$ rails g model Users last_name:string first_name:string
$ rails g scaffold User name:string email:string

$ git reset --hard     # to reset and blow away all changes

$ rake db:migrate
$ rake db:test:prepare
$ heroku run rake db:migrate

$ rake db:reset

# For running RSpec with a beep at the end
$ clear; time bin/rspec spec/; beep -l 2;

# For precompiling assets (and cleaning the folder first, before you upload to Heroku)
$ clear; git rm -rf public/assets; rm -rf public/assets; bin/rake assets:precompile; beep -l 2;


# For telling "rails server" in development that you don't want pre-compiled assets
# in config/environments/development.rb, add this (on advice of StackOverflow)
config.serve_static_assets = false

Database Setup
Don't forget to setup your database!
(If you do, you'll get a PG Error that says:
      fe_sendauth: no password supplied )

To setup the database, you'll need to edit config/database.yml
to include something like this.  (Don't worry about the production data, as it will be overwritten when you upload the site to Heroku.)

database.yml begin ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
# PostgreSQL. Versions 7.4 and 8.x are supported.

development:
  adapter: postgresql
  encoding: unicode
  database: myapp_development
  pool: 5
  host: localhost
  port: 5432
  username: myapp
  password: myapp_password

test:
  adapter: postgresql
  encoding: unicode
  database: myapp_test
  pool: 5
  host: localhost
  port: 5432
  username: myapp
  password: myapp_password

production:
  adapter: postgresql
  encoding: unicode
  database: myapp_production
  pool: 5
  host: localhost
  port: 5432
  username: myapp
  password: myapp_password
database.yml end ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
