Update to Rails 5.0.0.rc1 from 4.2
Just updated this blog to Rails 5.0.0.rc1 from 4.2, since this is a pretty small hobby blog app the update was quite simple and smooth.
1) Update your Gemfile, then bundle update rails
# core part of rails 5
gem 'rails', '~> 5.0.0.rc1'
gem 'turbolinks', '~> 5.x'
# use the same web server
gem 'puma', '~> 3.0'
# use latest master branch to make bundle resolve dependencies
gem 'kaminari', github: 'amatsuda/kaminari'
gem 'simple_form', github: 'plataformatec/simple_form'
gem 'rspec-rails', github: 'rspec/rspec-rails', tag: 'v3.5.0.beta3'
# Fix for https://github.com/jnicklas/capybara/issues/1592
gem 'capybara', github: 'jnicklas/capybara'
2) rails app:update to update the configuration files(config/*, bin/*)
Use d to check the diff and y to overwrite if it’s ok.
3) Create app/models/application_record.rb like this
class ApplicationRecord < ActiveRecord::Base
self.abstract_class = true
end
4) Update for turbolinks
This is equal to bind on window.onload, DOMContentLoaded, or jQuery ready events
$(document).on "turbolinks:load", ->
