My Git Workflow

Project workflow:

  1. Load/Reload waffle.
  • Get most current list of actions for the project.
  1. 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.
  1. git checkout master
  2. git pull origin master
  • Ensure you're starting on the master branch and have the most recent changes pulled down.
  1. run rspec
  • Make sure there are no outstanding issues with code on master.

VasylShevchenko / rails_setup.md
Created March 13, 2020 21:29 — forked from ryanflach/rails_setup.md
Common setup for a new Rails project
  1. 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
  1. 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)
  • Inside of group :test:
    • gem 'rspec-rails' - user rspec in place of minitest (docs)
