Southwest Checkin 2.X

Build Status

Deploy

Automatically checks in passengers for their Southwest Flight.

Version 2.0 of this project is a complete rewrite of the service. The brittle HTML parsing and form submissions are a thing of the past. A much better approach is being taken to automate checkins. And, importantly, the new version has a robust test suite. It is even written in a new language (Ruby) and framework (Rails).

If you are interested in the old version, see the 1.0 branch.

Create a config file replace your website, email, and email server. It must accept mail on port 587 with tls. You can use .env.example as a template

echo 'SITE_NAME=Southwest Checkin

Old but maybe useful bits

Heroku Installation

  1. While not strictly required, it is recommended to install rbenv and ruby-build to manage ruby versions in development. Ruby 2.2 or greater is required.

    • Note: Replace anything inside of <> with your projects information.
    • Note: These instructions do not include steps to add email support.
    • Note: This tutorial assumes you're using a Mac with OSX, if you're running something else you may need to make a few adjustments for your OS but should work mostly the same.
    • Note: I recommend using Homebrew to install dependencies.
  2. Required dependencies

  3. Setup heroku and download latest version of the code:

    • Create an account on Heroku
    • From the Heroku web interface create a new app
    • From the Heroku web interface add the following resources to your project:
      • Redis To Go
      • Heroku Postgres
    • Create a folder and cd into it using Terminal
    cd Your/Project/Folder
    git clone https://github.com/aortbals/southwest-checkin.git
    heroku git:remote -a <YOUR_HEROKU_APP_NAME>
  4. Get sidekiq to load the redis add-on's URL

    heroku config:set REDIS_PROVIDER=REDISTOGO_URL
  5. Add ruby version to Gemfile:

    • Open the Gemfile located in the project folder and add the following lines near the top, right below source 'https://rubygems.org'"
    ruby '2.2.0'
    gem 'rails_12factor', group: :production
    
  6. Configure Heroku:

    heroku config:set SITE_NAME='Southwest Checkin' SITE_URL=<HEROKU_URL> ASSET_HOST=<HEROKU_URL> MAILER_DEFAULT_FROM_EMAIL=<YOUR_EMAIL> MAILER_DEFAULT_REPLY_TO=<YOUR_EMAIL> DEPLOY_BRANCH=master DEPLOY_USER=deploy DEPLOY_PORT=22
  7. After installing the aforementioned dependencies (see step 2), install the ruby dependencies:

    gem install bundler
    bundle install
  8. Now commit and push your app to heroku:

    git add .
    git commit -am ""
    git push heroku master
  9. Create and seed the database:

    heroku run rake db:create db:migrate db:seed
  10. (Optional) Setup email with Mailgun

    • From the Heroku web interface add the following resource to your project:
      • Mailgun
    • Once Mailgun is installed login to Mailgun (click on the Mailgun resource to automatically be logged in) and add your domain. This might not be necessary but it's the only way I could get it to work for me.
    • Once the domain has been verified, click on the domain to find the values for the following command and run it:
    heroku config:set MAILER_DEFAULT_FROM_EMAIL=<YOUR_EMAIL> MAILER_DEFAULT_REPLY_TO=<YOUR_EMAIL> MAILER_ADDRESS=<SMTP_HOSTNAME> MAILER_DOMAIN=<HEROKU_URL> MAILER_USERNAME=<DEFAULT_SMTP_LOGIN> MAILER_PASSWORD=<DEFAULT_PASSWORD>
  11. Now browse to your Heroku's app url and start adding reservations.

Create a script to launch everything

echo '#!/bin/sh
service postgresql restart
service redis-server restart
sleep 2
echo Starting rails
tmux new -s rails  -d
tmux send-keys  -t rails "cd /root/southwest-checkin/app" C-m
tmux send-keys  -t rails "/root/.rbenv/shims/rails s -b 0.0.0.0 -p 80 -e development" C-m
tmux new -s sidekiq -d
sleep 2
echo Starting sidekiq
tmux send-keys  -t sidekiq "cd /root/southwest-checkin" C-m
tmux send-keys  -t sidekiq "/root/.rbenv/shims/bundle exec sidekiq &" C-m' > /root/start.sh
