BookmarkSystem

An active record bookmark system developed using ruby on rails 4.1 applying domain driven design and test driven development principles.

This gem is heavily influenced by cmer/socialization.

Installation

Add this line to your application's Gemfile:

gem 'bookmark_system'

And then execute:

$ bundle

Or install it yourself as:

$ gem install bookmark_system

Usage

Run the generator

$ rails g bookmark_system

Let's suppose for a moment that you have a blog application and a User can bookmark a Post or several Post models. The user model becomes the bookmarker and the post model becomes the bookmarkee.

Post object

class Post < ActiveRecord::Base
  act_as_bookmarkee

  validates :content, presence: true
end

User object

class User < ActiveRecord::Base
  act_as_bookmarker

  validates :username, { presence: true, uniqueness: true }
end

Bookmarkee object methods

post.is_bookmarkee? # returns true

post.bookmarked_by?(user) # returns true if user bookmarks the post object, false otherwise

post.bookmarkers_by(User) # returns a scope of BookmarkSystem::Bookmark join model that belongs to the post object and belongs to bookmarker objects of type User

Bookmarker object methods

user.is_bookmarker? # returns true

user.bookmark(post) # Creates an instance of BookmarkSystem::Bookmark join model associating the user object and the post object, returns true if succeded, false otherwise

user.unbookmark(post) # Destroys an instance of BookmarkSystem::Bookmark join model that associates the user object and the post object, returns true if succeded, false otherwise

user.toggle_bookmark(post) # Bookmarks / unbookmarks the post

user.bookmarks?(post) # returns true if the user object bookmarks the post object, false otherwise

user.bookmarkees_by(Post) # returns a scope of BookmarkSystem::Bookmark join model that belongs to the user object and belongs to bookmarkee objects of type Post
