Comfy cms.
Add gem definition to your Gemfile:
gem "comfy_blog", "~> 2.0.0"
Then from the Rails project's root run:
bundle install
rails generate comfy:blog
rake db:migrate
Take a look inside your config/routes.rb file and you should see following lines there:
comfy_route :blog_admin, path: "admin"
comfy_route :blog, path: "blog"
You should also find view templates in /app/views/blog folder. Feel free to adjust them as you see fit.
