BlogBoi is a rails gem / engine that provides out-of-the-box blogging functionality to your rails application.

It requires active_storage for photo upload / storage.

1. Add this line to your application's Gemfile:

gem 'blog_boi', '~> 0'

2. Add these lines to your config/application.rb file:

require "active_storage/engine" # If doesn't exist already

ActiveStorage::Engine.config
.active_storage
.content_types_to_serve_as_binary
.delete('image/svg+xml')

3. And then execute:

$ bundle
$ rake active_storage:install `# If hasn't been run yet`
$ rake active_storage:update # if upgrading to rails 6
$ rails blog_boi:install:migrations `# not needed for dummy test application`
$ rails db:migrate

Your storage.yml file should now have this code:

test:
	service: Disk
	root: <%= Rails.root.join("tmp/storage") %>

local:
	service: Disk
	root: <%= Rails.root.join("storage") %>

Note: $ rails railties:install:migrations to copy all new migrations Note: to run migrations only for certain engine, rails db:migrate SCOPE=blog_boi. To revert all migrations from blog_boi engine you can run rails db:migrate SCOPE=blog_boi VERSION=0

4. And then mount the engine in your app's config/routes.rb file:

mount BlogBoi::Engine, at: "/blog"

5. Customize scss colour scheme by creating stylesheets/bootstrap_customizer.scss. See example in test/dummy/app/assets/stylesheets.

6. And then add the engines configuration options in an initializer file (named blog_boi.rb):

BlogBoi.author_class = "User" # name of active record model containing authors with property called name (for author's name)

See lib/blog_boi.rb for all customization options (like setting your Blog's meta description / image).

7. Finally, your parent application must define the method admin_signed_in?. If you are using Devise, this method may already exist. It should return true if the blog admin is signed in, and false if not. When it returns true, you may create, update, and destroy blog articles. It should be available in controllers and views; it should be defined in ApplicationController, and should be marked a helper method. E.g.

class ApplicationController < ActionController::Base

	helper_method :admin_signed_in?

	def admin_signed_in?
		...
	end

end

List of view partial hooks that are rendered if they exist in parent application:

• layouts/blog_boi/head_extension: (for adding html to head of blog_boi application layout in layouts/blog_boi/application)

To override SCSS bootstrap mixins / styles, add a file in parent application called blog_boi/bootstrap_overrides.scss.

• See test/dummy app for example
• https://getbootstrap.com/docs/4.0/getting-started/theming/ for theming examples (any colours you add, like c1, can be used like btn-c1. Very cool)

Override the header or footer by placing your own files at views/layouts/_header or views/layouts/_footer

Further, you can add your own css classes / ids to your markup:

• {: .cls}

• Run system tests: rake app:test:system
• Run all tests: rake or rake test
