Rails Base

Build Status Test Coverage Code Climate

Rails Base is the base Rails application template used at Flatstack. It's based on Rails 4 and Ruby 2.3.1.

Application Gems

Development Gems

  • Puma as Rails web server
  • Foreman for managing development stack with Procfile
  • Letter Opener for opening mail in the browser instead of sending it
  • Bullet for detecting N+1 queries and unused eager loading
  • Rubocop and Rubocop-Rspec for reporting violations of the Ruby style guide
  • Brakeman for checking application for common security vulnerabilities
  • Pry Rails for interactively exploring objects
  • Bundler Audit for scanning the Gemfile for insecure dependencies based on published CVEs
  • Spring for fast Rails actions via pre-loading
  • Web Console for better debugging via in-browser IRB consoles
  • SCSS-Lint for reporting violations of SCSS coding conventions
  • Coffeelint to keep Coffeescript code clean and consistent
  • Slim-Lint for reporting violations of Ruby style guide in .slim templates
  • Rails ERD for generating a diagram based on application's AR models

Testing Gems


  • mailer.rb - setup default hosts for mailer from configuration
  • requires.rb - automatically requires everything in lib/ & lib/extensions


  • bin/setup - setup required gems and migrate db if needed
  • bin/quality - runs rubocop, brakeman, rails_best_practices and bundle-audit for the app
  • bin/ci - should be used in the CI or locally
  • bin/server - to run server locally

Getting Started

Prepare dependencies

Some gems have native extensions. You should have GCC installed on your development machine.

  • qt - to run specs with Capybara Webkit
  • phantomjs198 - to run Javascript unit tests
  • graphviz - to generate Entity-Relationship Diagram

Setup required dependencies from Brewfile:

brew tap Homebrew/bundle
brew bundle

Bootstrap application

  1. Clone application as new project with original repository named "rails-base".

    git clone git:// --origin rails-base [MY-NEW-PROJECT]
  2. Create your new repo on GitHub and push master into it. Make sure master branch is tracking origin repo.

    git remote add origin[MY-GITHUB-ACCOUNT]/[MY-NEW-PROJECT].git
    git push -u origin master
  3. Run setup script

  4. Run test and quality suits to make sure all dependencies are satisfied and applications works correctly before making changes.

  5. Run app

  6. Update README

    Do not forget to update application file with detailed information based on the existing template.

    mv doc/
    # update
    git commit -am "Update"



Out of the box Rails Base ready to be deployed to

  • Heroku Postgres add-on will be used for database.
  • SendGrid add-on required to be able to send emails.
  • NewRelic add-on could be used to monitor application performance.
  • Rollbar add-on could be used to application errors.
heroku create --addons=heroku-postgresql,sendgrid,newrelic,rollbar --remote staging rails-base-example
heroku config:add HOST="" MAILER_SENDER_ADDRESS="" NEW_RELIC_APP_NAME="Rails Base"
git push staging master
heroku run rake db:schema:load
heroku open
