Inkwell

Build Status Code Climate Coverage Status

Inkwell provides a simple way to add social networking features (e.g., comments, reblogs, favorites, following/followers, communities and timelines) to your Ruby on Rails application.

Installation

To get Inkwell from RubyGems, put the following line in the Gemfile.

gem 'inkwell'

Alternatively, you can get it from Github (This version may contain unfinished features).

gem 'inkwell', :git => 'git://github.com/salkar/inkwell.git'

After that, run bundle install

Next, get gem migrations:

$ rake inkwell:install:migrations

and rake db:migrate them.

Upgrading

After upgrading Inkwell remember to get new migrations and migrate them.

$ rake inkwell:install:migrations
$ rake db:migrate

Usage

Favoriting features

Setup

Include relevant modules to models:

  • add include Inkwell::CanFavorite to models which instances should be able to favorite other objects
  • add include Inkwell::CanBeFavorited to models which instances should be able to be added to favorites

For sample:

# app/models/user.rb

class User < ApplicationRecord
  include Inkwell::CanFavorite
  #...
end

# app/models/post.rb

class Post < ApplicationRecord
  include Inkwell::CanBeFavorited
  #...
end

Inkwell::CanFavorite usage

Inkwell::CanFavorite#favorite(obj)

user.favorite(post)

After that post will appear in the user.favorites. Also if user sees post in someone else's timelines (or blog, favorites, etc.), post will have favorited_in_timeline attribute with true value.

Inkwell::CanFavorite#unfavorite(obj)

user.unfavorite(post)

Rolls back favorite effects.

Inkwell::CanFavorite#favorite?(obj)

user.favorite?(post)
#=> false
user.favorite(post)
#=> true
user.favorite?(post)
#=> true

Check that post is added to favorites by user.

Notice: if obj passed to favorite, unfavorite or favorite? does not include Inkwell::CanBeFavorited Inkwell::Errors::NotFavoritable will be raised

Inkwell::CanFavorite#favorites(for_viewer: nil, &block)

Return array of instances favorited by object.

user.favorites
#=> [#<Post>, #<Comment>, ...]

If favorites used without block, all favorited objects will be returned (without pagination, ordering, etc). In this case Array is returned not Relation!

For perform operations on relation block should be used:

# Gemfile
gem 'kaminari'

# code

user.favorites do |relation|
  relation.page(1).order('created_at DESC')
end
#=> [#<Post>, #<Comment>, ...]

Notice: relation is relation of Inkwell::Favorite instances (internal Inkwell model)

Notice: realization with block looks complicated, but it helps with solve troubles with many-to-many relations through other polymorphic relations on both sides.

If there is necessary to get each result's object with flags for another user (favorited_in_timeline, reblogged_in_timeline, etc.), for_viewer should be passed:

user.favorite(post)
user.favorite(other_post)
other_user.favorite(other_post)
result = user.favorites(for_viewer: other_user)
result.detect{|item| item == post}.favorited_in_timeline
#=> false
result.detect{|item| item == other_post}.favorited_in_timeline
#=> true
Inkwell::CanFavorite#favorites_count

post.favorited_by.each do |obj|
  obj.favorites_count
end

Use favorites_count (instead of obj.favorites.count or obj.inkwell_favorited.count for sample) for prevent n+1 because favorites_count get counter from inkwell cache included in favorited_by by default.

Inkwell::CanBeFavorited usage

Inkwell::CanBeFavorited#favorited_by?(subject)

post.favorited_by?(user)
#=> false
user.favorite(post)
#=> true
post.favorited_by?(user)
#=> true

Check that post is added to favorites by user.

Notice: if subject does not include Inkwell::CanFavorite Inkwell::Errors::CannotFavorite will be raised

Inkwell::CanBeFavorited#favorited_count

user.favorites.each do |obj|
  obj.favorited_count
end

Use favorited_count (instead of obj.favorited_by.count or obj.inkwell_favorited.count for sample) for prevent n+1 because favorites_count get counter from inkwell cache included in favorites by default.

Inkwell::CanBeFavorited#favorited_by(&block)

Return array of instances who favorite this object.

post.favorited_by
#=> [#<User>, #<Community>, ...] # Array, NOT Relation
# Gemfile
gem 'kaminari'

# code

user.favorited_by do |relation|
  # relation - Inkwell::Favorite relation
  relation.page(1).order('created_at DESC')
end
#=> [#<User>, #<Community>, ...] # Array, NOT Relation

Notice: for more details see Inkwell::CanFavorite#favorites . It works the same way.

Blogging features

Setup

Include relevant modules to models:

  • add include Inkwell::CanBlogging to models which instances should be able to add objects to their blog.
  • add include Inkwell::CanBeBlogged to models which instances should be able to be added to blogs.

For sample:

# app/models/user.rb

class User < ApplicationRecord
  include Inkwell::CanBlogging
  #...
end

# app/models/post.rb

class Post < ApplicationRecord
  include Inkwell::CanBeBlogged
  #...
end

To automatically add posts to user blog, you can do the following:

class Post < ApplicationRecord
  include Inkwell::CanBeBlogged
  #...
  belongs_to :user
  #...
  validates :user, presence: true
  #...
  after_create :blog_filling
  #...
  private

  def blog_filling
    user.add_to_blog(self)
  end
end

Inkwell::CanBlogging usage

Inkwell::CanBlogging#add_to_blog(obj)

user.add_to_blog(post)

After that post will appear in the user.blog.

Inkwell::CanBlogging#remove_from_blog(obj)

user.remove_from_blog(post)

Rolls back add_to_blog effects.

Inkwell::CanBlogging#added_to_blog?(obj)

user.added_to_blog?(post)
#=> false
user.add_to_blog(post)
#=> true
user.added_to_blog?(post)
#=> true

Check that post is added to user's blog.

Notice: if obj passed to add_to_blog, remove_from_blog or added_to_blog? does not include Inkwell::CanBeBlogged Inkwell::Errors::NotBloggable will be raised

Inkwell::CanBlogging#blog(for_viewer: nil, &block)

Return array of instances blogged and reblogged by object.

user.blogs
#=> [#<Post>, #<Comment>, ...] # array NOT relation
# Gemfile
gem 'kaminari'

# code

user.blogs do |relation|
  # relation - Inkwell::BlogItem relation
  relation.page(1).order('created_at DESC')
end
#=> [#<Post>, #<Comment>, ...]

Reblogged items has reblog_in_timeline flag

  user.add_to_blog(post)
  user.reblog(other_post)
  result = user.blogs
  result.detect{|item| item == post}.reblog_in_timeline
  #=> false
  result.detect{|item| item == other_post}.reblog_in_timeline
  #=> true

If there is necessary to get each result's object with flags for another user (reblogged_in_timeline, favorited_in_timeline, etc.), for_viewer should be passed:

user.add_to_blog(post)
user.add_to_blog(other_post)
other_user.reblog(other_post)
result = user.blog(for_viewer: other_user)
result.detect{|item| item == post}.reblogged_in_timeline
#=> false
result.detect{|item| item == other_post}.reblogged_in_timeline
#=> true

Notice: for more details see Inkwell::CanFavorite#favorites . It works the same way.

Inkwell::CanBlogging#blog_items_count

Return added to blog objects count (including reblogs).

user.blog_items_count

Use blog_items_count for prevent n+1.

Inkwell::CanBeBlogged usage

Inkwell::CanBeBlogged#blogged_by?(subject)

post.blogged_by?(user)
#=> false
user.add_to_blog(post)
#=> true
post.blogged_by?(user)
#=> true

Check that post is added to user's blog.

Notice: if subject does not include Inkwell::CanBlogging Inkwell::Errors::CannotBlogging will be raised

Inkwell::CanBeFavorited#blogged_by

Return instance who add to blog this object (owner of this object).

user.add_to_blog(post)
post.blogged_by
#=> #<User> # user

Setup

Include relevant modules to models:

  • add include Inkwell::CanReblog to models which instances should be able to reblog objects. If object is reblogged, it is added to subject's blog.

  include Inkwell::CanBlogging
  include Inkwell::CanReblog
  #...
end

# app/models/post.rb

class Post < ApplicationRecord
