UPDATE.md

Updating process

• In the outer directory install latest rails, using latest ruby:

  $ rvm get stable
  $ rvm use ruby-prev.version
  $ rvm gemset delete mayak
  $ rvm install ruby-new.version
  $ rvm --default use ruby-new.version
  $ rvm gemset create mayak
  $ rvm gemset use mayak
  $ gem install bundler
  $ gem install --no-rdoc --no-ri rails -v rails.new.version
  $ rails new mayak --skip-bundle --skip-test-unit --database=postgresql
  $ mv mayak rails_new.version
  

• Save this directory until next update unchanged - any chages do with a copy

• Generate scaffold for test in the new directory:

  $ bin/bundle install
  $ bin/rails generate scaffold Author name:string
  $ bin/rails generate scaffold Article author:belongs_to source:references{polymorphic} title:string slug:string:index published_at:datetime:index image:string intro:text body:text seodata:text hided:boolean:index
  $ bin/rake db:drop db:create db:migrate
  

• Save scaffolded version for future

• Diff with previous scaffolded rails and analyse changes for update current version of Mayak

• Copy new rails files (without scaffold) to mayaknew folder

• Merge 'Gemfile' from old Mayak with updating versions of gems

• Run bin/bundle install --without production and generate all configs:

  bin/rails g active_admin:install
  bin/rails g kaminari:config
  bin/rails g uploader Avatar
  bin/rake sitemap:install
  bin/bundle exec wheneverize .
  bin/bundle exec mina init
  

• Carefully merge Mayak to new instance

• Remove old Mayak files except '.git' directory

• Move all new Mayak files to old directory with '.git' inside

• Run bin/rake db:drop db:create db:migrate db:seed

• Update information about software versions in the readme file and in the admin dashboard file.

• Check all changes using git diff : we need to be sure that we didn't lost anything important

• Run bin/rails server and check result manually

• git add . && git commit -m "Update to Ruby new.version and Rails new.version" && git push - Le Roi est mort, vive le Roi!
