                Common setup for a new Rails project
              
          
rails new <project_name> -d postgresql --skip-turbolinks --skip-spring -T


-d postgresql sets up the project to use PostgreSQL
--skip-turbolinks & --skip-spring creates a project that does not use turbolinks or spring
-T skips the creation of the test directory and use of Test::Unit


In the Gemfile:


Available to all environments:

gem 'figaro' - store environment variables securely across your app (docs)
Uncomment gem 'bcrypt', '~> 3.1.7' if you will be hosting your own user accounts with passwords (docs)

                My Git Workflow
              
          
    Project workflow:


Load/Reload waffle.


Get most current list of actions for the project.


Choose a card from the backlog in waffle. If we're working separately, it's best to move that card that you've chosen into ready and perhaps assign it to yourself as well.


Make sure multiple team members aren't working on the same issue; ensure everyone knows what each other is working on.


git checkout master
git pull origin master


Ensure you're starting on the master branch and have the most recent changes pulled down.


run rspec


Make sure there are no outstanding issues with code on master.
