Inkwell

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

Russian translation of README file available here.

Requirements

You should have two classes: User and Post or other identical. Between them should be a one-to-many relationship. For example:

class User < ActiveRecord::Base
  has_many :posts
end

class Post < ActiveRecord::Base
  belongs_to :user
end

If you want to use communities, then you need to have Community class, too:

class Community < ActiveRecord::Base
end

Installation

Put in Gemfile:

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

After it do bundle install

Add to your User model acts_as_inkwell_user and to your Post model acts_as_inkwell_post

class User < ActiveRecord::Base
  has_many :posts
  acts_as_inkwell_user
end

class Post < ActiveRecord::Base
  belongs_to :user
  acts_as_inkwell_post
end

If you want to use communities, then add to your Community model acts_as_inkwell_community:

class Community < ActiveRecord::Base
  acts_as_inkwell_community
end

Create inkwell.rb file in config/initializers and put in it your names of User and Post tables (or other identical). Put in it name of Community table if you want to use it:

module Inkwell
  class Engine < Rails::Engine
    config.post_table = :posts
    config.user_table = :users
    config.community_table = :communities #if you want to use communities
  end
end

Next, get gem migrations:

rake inkwell:install:migrations

and db:migrate it.

Usage

Favorite features

User is able to favorite posts/comments:

@user.favorite @post
@user.favorite @comment

To delete post/comment from favorites:

@user.unfavorite @post

To check that post/comment enters in favorites:

@user.favorite? @post

To return favorite line, consisting of favorited posts and comments:

@user.favoriteline(:last_shown_obj_id => nil, :limit => 10, :for_user => nil)

where

  • last_shown_obj_id - id of the last item in favorite line shown to the user. Get it from the item_id_in_line property of last item from previous favoriteline calls. This parameter is used for pagination and separation of the timeline.

    fline = @user.favoriteline    #get first 10 items from @user favorite line
    last_shown_obj_id = fline.last.item_id_in_line
    fline_next_page = @user.favoriteline :last_shown_obj_id => last_shown_obj_id    #get next 10 items from @user favorite line
    
  • limit - defines the count of favorited items to return.

    fline = @user.favoriteline :limit => 20    #return first 20 items from @user favorite line
    
  • for_user - User, who looks this favorite line. For him is_reblogged and is_favorited properties will been formed.

    @user.favorite @another_user_post
    @user.reblog @another_user_post
    
    fline_for_unknown_user = @another_user.favoriteline
    # For example, fline_for_unknown_user.first == @another_user_post
    fline_for_unknown_user.first.is_reblogged    # => false
    fline_for_unknown_user.first.is_favorited    # => false
    
    fline_for_user_who_reblog_and_favorite_another_user_post = @another_user.favoriteline :for_user => @user
    # For example, fline_for_user_who_reblog_and_favorite_another_user_post.first == @another_user_post
    fline_for_user_who_reblog_and_favorite_another_user_post.first.is_reblogged    # => true
    fline_for_user_who_reblog_and_favorite_another_user_post.first.is_favorited    # => true
    

More examples you can find in this spec.

Reblog features

Reblog means that reblogged post will be added to user’s blogline and to timelines of his followers. Thus, the behavior of reblogged object is similar to the post of the user who made this reblog. User is able to reblog posts/comments:

@user.reblog @post
@user.reblog @comment

To delete post/comment from reblogs:

@user.unreblog @post

To check that post/comment enters in reblogs:

@user.reblog? @post

Reblogs don’t have their own line and are contained in user’s blogline.

More examples you can find in this spec.

Comment features

User is able to create comments for post or other comment. If you want to comment the post:

@user.comments.create :post_id => @post.id, :body => "comment_body"

If you want to comment other comment you should add parent_id of parent comment:

@user.comments.create :post_id => @parent_post.id, :body => "comment_body", :parent_id => @parent_comment.id

To delete comment you should use destroy method:

@comment.destroy

You are able to get comment line for post or comment. It consists of comments for this object in reverse chronological order.

Notice: returned array will have back order to simplify the use. Last comment is at the bottom usually.

To get comment line:

commentline(:last_shown_comment_id => nil, :limit => 10, :for_user => nil)

where last_shown_comment_id is id of last shown comment from previous commentline results. For example:

cline = @post.commentline    #get last 10 comments for @post
last_shown_comment_id = cline.first.id    # First element is taken due to reverse order. In fact, it is the oldest of these comments.
cline_next_page = @post.commentline :last_shown_comment_id => last_shown_comment_id

Limit and for_user mean the same thing as in the favoriteline.

More examples you can find in this spec.

Follow features

User is able to follow another users. It allows him to get followed user’s blogline in his timeline.

To follow user:

@user.follow @another_user

After it last 10 @another_user blogline’s items will be transferred to @user timeline. And each new @another_user blogline item will be added to @user timeline.

To unfollow user:

@user.unfollow @another_user

To check that user is follower of another user:

@user.follow? @another_user

To get followers ids for user and ids of users, which he follow:

@user.followers_row
@user.followings_row

Both methods return arrays of ids.

More examples you can find in this spec.

Blogline feature

Community feature

Community is association of users. It has own blogline, consisting of posts of its members. Community member can send his post to the community blogline. Then this post is added to the timelines of other community users.

When you create community you need to pass owner_id:

@community = Community.create :name => "Community", :owner_id => @user.id

User with the passed id will be the first administrator of created community and will be added to it.

To add a user to the open community:

@user.join @community

To remove a user from community:

@admin.kick :user => @user, :from_community => @community

where admin is community administrator and @user is deleted user.

If user leave community:

@user.leave @community

After leaving the community (both methods) its blogline items will be removed from the user timeline.

To send post to the community blogline:

@user.send_post_to_community :post => @user_post, :to_community => @community

Sent post will be added to timelines of community members. A post can be sent to the community only by its owner.

To remove post from community blogline:

@user.remove_post_from_community :post => @user_post, :from_community => @community

or

@admin.remove_post_from_community :post => @user_post, :from_community => @community

Only post owner or administrator of community can remove the post from the community blogline.

To check that the user is a member of the community:

@community.include_user? @user

To check that the user is an admin of the community:

@community.include_admin? @user

Each administrator has the access level. Community owner has access level 0. Administrators, to whom he granted admin permissions, have access level 1 and so on. Thus the lower the access level, the more permissions. For example, admin with access level 0 can delete admin with access level 1 but not vice versa.

To grant admin permissions:

@admin.grant_admin_permissions :to_user => @new_admin, :in_community => @community

To revoke admin permissions:

@admin.revoke_admin_permissions :user => @admin_who_is_removed, :in_community => @community

To get admin’s access level:

@community.admin_level_of @admin

To get communities ids in which there is this post:

@post.communities_row

To get ids of community members:

@community.users_row

To get ids of communities to which the user has joined:

@user.communities_row

Community blogline is consists of the posts of members that have added to it. To get it:

@community.blogline(:last_shown_obj_id => nil, :limit => 10, :for_user => nil)

where parameters are similar with described above favoriteline parameters.
