Help you implement feeds / timeline in rails application.
Add this line to your application's Gemfile:
gem 'my_feeds'
And then execute:
$ bundle
Or install it yourself as:
$ gem install my_feeds
my_feeds need feeder, eater and associate model
feeder publish feeds
eater receive publish
and associate model create a relation between feeder and eater
yes, like subscribe and publish
feed model is what feeder published and eater subscribed, you can customize it.
rails generate my_feeds
rails generate my_feeds:likes
you can also use your own associate model.
just make sure your model have a polymorphic field for feeder.
and
class YourCustomModel < ActiveRecord::Base
include MyFeeds::Associate #make sure include this module
init_feeds_polymorphic = :likeable #and set this, in this case is likeable, it should same as the polymorphic belongs_to
#same as feeds_polymorphic
belongs_to :likeable, polymorphic: true
end
# you should create a migration like below
# in this case, this column name is likeable_identity, it depends on feeds_polymorphic
#add_column :your_customs, :likeable_identity, :string, null: false
include MyFeeds::Feeder in your model which will as feed source
class User < ActiveRecord::Base
...
include MyFeeds::Feeder
...
endnow User get a method define_feed_event
use define_feed_event define your feed_event
class User < ActiveRecord::Base
...
include MyFeeds::Feeder
define_feed_event :hahahaha
define_feed_event :kakakaka
...
end
#in you rails console
user = User.create ...
#user get a method hahahaha...
#will create 3 feeds
user.hahahaha
user.hahahaha
user.hahahaha
#you can use source_feeds associate fetch your source feeds
user.source_feeds.count #=> 3
#or scoped version
user.hahahaha_feeds.count #=> 3
user.kakakaka_feeds.count #=> 0
#you can pass extra arguments to feed_event method, but must match feed model attributes
user.hahahaha target_id: another_user.id, target_type: another_user.class
user.source_feeds.last.target_id #=> another_user.id
#you can also passed arguments with define_feed_event, then arguments will be default
...
define_feed_event :hahahaha, target_type: User
...
user.hahahaha target_id: another_user.id
user.source_feeds.last.target_type #=> Userinclude MyFeeds::Eater in your model which will as feed receiver
class User < ActiveRecord::Base
...
include MyFeeds::Eater
has_many :likes #a eater must have associate with feeder
def feeds
#eater have method feeds_for, pass associate and return feeds
feeds_for likes
end
...
end
##sample
#create relation
u = User.create
like = u.likes.new
like.likeable = another_user
like.save
like = u.likes.new
like.likeable = Post.find ...
like.save
u.feeds #=> you get feeds
##feeds with scope??
class User < ActiveRecord::Base
...
include MyFeeds::Eater
has_many :likes #a eater must have associate with feeder
def feeds
#eater have method feeds_for, pass associate and return feeds
feeds_for likes
end
def teams_feeds
feeds_for likes.where(likeable_type: Team)
end
def users_posts_feeds
feeds_for(likes.where likeable_type: User).where(target_type: Post)
end
...
