Reddit on Rails Update

What follows are the things I had to do to update the Reddit on Rails project to Rails 5.

Create A New Project

rails new reddit_on_rails --database=postgresql

Add Gems

Comment in BCrypt.

Add:

gem 'jquery-rails'

Add to :development, :test:

gem 'shoulda-matchers', git: 'https://github.com/thoughtbot/shoulda-matchers.git', branch: 'rails-5'
gem 'rails-controller-testing'
gem 'rspec-rails', '~> 3.5'
gem 'factory-girl-rails'

Add to :development:

gem 'pry-rails'
gem 'byebug'
gem 'better_errors'
gem 'binding_of_caller'

Run bundle install.

Setup RSpec

Run rails g rspec:install.

Add shoulda_matchers configuration. In the rails_helper.rb:

require 'shoulda/matchers'

RSpec.configure do |config|
#...

  Shoulda::Matchers.configure do |config|
    config.integrate do |with|
      with.test_framework :rspec
      with.library :rails
    end
  end

#...
end

Generate The Models

Run rails db:create. The create the following:

Routes

I then copied all of the routes in.

Controllers

Users

Copy the controller content.

Copy the controller tests.

Make sure that the params are properly nested in the controller tests.

Views

I then copied and pasted all of the non-layout views folders into the new project.

Remove initialized .git

Rails initializes with a git folder. Remove it.

Re-Zip

Zip the project up.

Readme

After all of this, I made sure that the Readme was good to go.

For the Gemfile, "factory-girl-rails" should be "factory_girl_rails".
