How to migrate from youtube_it

If you are used to access the YouTube API with youtube_it, this guide will help you translate your code to use Yt instead.

This guide follows youtube_it README.rdoc listing the original youtube_it commands and their equivalent Yt versions.

Establishing a client

While youtube_it supports authentication with developer key, AuthSub and OAuth, Yt only supports OAuth 2.0, because this is the only process that has not been deprecated by YouTube Data API V3.

Another difference is that youtube_it authentication methods are invoked on a generic Client class, while with Yt you can specify whether you want to authenticate as a YouTube Account or as a ContentOwner. Content owners are special CMS accounts that can manage multiple YouTube accounts at once.

Creating a client:

# with youtube_it
client = YouTubeIt::Client.new
# with yt
account = Yt::Account.new # or Yt::ContentOwner.new

Client with developer key:

# with youtube_it
client = YouTubeIt::Client.new(:dev_key => "developer_key")
# with yt: not supported (must use OAuth 2.0)

Client with youtube account and developer key:

# with youtube_it
client = YouTubeIt::Client.new(:username => "youtube_username", :password =>  "youtube_passwd", :dev_key => "developer_key")
# with yt: not supported (must use OAuth 2.0)

Client with AuthSub:

# with youtube_it
client = YouTubeIt::AuthSubClient.new(:token => "token" , :dev_key => "developer_key")
# with yt: not supported (must use OAuth 2.0)

Client with OAuth:

# with youtube_it
client = YouTubeIt::OAuthClient.new("consumer_key", "consumer_secret", "youtube_username", "developer_key")
client.authorize_from_access("access_token", "access_secret")
# with yt: not supported (must use OAuth 2.0)

Client with OAuth2:

# with youtube_it
client = YouTubeIt::OAuth2Client.new(client_access_token: "access_token", client_refresh_token: "refresh_token", client_id: "client_id", client_secret: "client_secret", dev_key: "dev_key", expires_at: "expiration time")
client.refresh_access_token!
# with yt
Yt.configure do |config|
  config.client_id = 'client_id'
  config.client_secret = 'client_secret'
end
account = Yt::Account.new access_token: 'access_token', refresh_token: 'refresh_token'

Profiles

With youtube_it, you can use multiple profiles in the same account:

profiles = client.profiles(['username1','username2'])
profiles['username1'].username, "username1"

With yt, you can access all the channels managed by the same YouTube account:

first_channel = Yt::Channel.new id: 'UCx12345', auth: account
second_channel = Yt::Channel.new id: 'UCy45678', auth: account
first_channel.title

Video queries

List videos by keyword:

# with youtube_it
client = YouTubeIt::Client.new
client.videos_by(:query => "penguin")
# with yt
videos = Yt::Collections::Videos.new
videos.where(q: 'penguin')

List videos by page:

# with youtube_it
client = YouTubeIt::Client.new
client.videos_by(:query => "penguin", :page => 2, :per_page => 15)
# with yt: pagination is automatically supported by collection, which iterates
# though all the pages, not just the first one
videos = Yt::Collections::Videos.new
videos.where(q: 'penguin')

List videos by region:

# with youtube_it
client = YouTubeIt::Client.new
client.videos_by(:query => "penguin", :restriction => "DE")
# with yt
# Note that some users report that regionCode does not work in YouTube API V3
# See https://code.google.com/p/gdata-issues/issues/detail?id=4110
videos = Yt::Collections::Videos.new
videos.where(q: 'penguin', region_code: 'DE')

List videos by author:

# with youtube_it
client = YouTubeIt::Client.new
client.videos_by(:query => "penguin",  :author => "liz")
# with yt: the 'author' filter was removed from YouTube API V3, so the
# request must be done using the channel of the requested author
channel = Yt::Channel.new url: 'youtube.com/liz'
channel.videos.where(q: 'penguin')

List videos by categories:

# with youtube_it
client = YouTubeIt::Client.new
client.videos_by(:categories => [:news, :sports])
# with yt: the 'categories' filter was removed from YouTube API V3, so the
# request must be done using one category_id at the time
videos = Yt::Collections::Videos.new
videos.where(video_category_id: 25) #=> News
videos.where(video_category_id: 17) #=> Sports

List videos by tags:

# with youtube_it
client = YouTubeIt::Client.new
client.videos_by(:tags => ['tiger', 'leopard'])
client.videos_by(:categories => [:news, :sports], :tags => ['soccer', 'football'])
# with yt: not supported (was removed from YouTube API V3)

List videos by user:

# with youtube_it
client = YouTubeIt::Client.new
client.videos_by(:user => 'liz')
# with yt: the 'author' filter was removed from YouTube API V3, so the
# request must be done using the channel of the requested author
channel = Yt::Channel.new url: 'youtube.com/liz'
channel.videos.where(q: 'penguin')

List videos favorited by user:

# with youtube_it
client = YouTubeIt::Client.new
client.videos_by(:favorites, :user => 'liz')
# with yt: note that only *old* channels have a "Favorites" playlist, since
# "Favorites" has been deprecated by YouTube in favor of "Liked Videos".
channel = Yt::Channel.new url: 'youtube.com/liz'
channel.related_playlists.find{|p| p.title == 'Favorites'}

Retrieve video by ID:

# with youtube_it
client = YouTubeIt::Client.new
client.video_by("FQK1URcxmb4")
# with yt
Yt::Video.new id: 'FQK1URcxmb4'

Retrieve video by URL:

# with youtube_it
client = YouTubeIt::Client.new
client.video_by("https://www.youtube.com/watch?v=QsbmrCtiEUU")
# with yt
Yt::Video.new url: 'https://www.youtube.com/watch?v=QsbmrCtiEUU'

Retrieve video of a user by ID:

# with youtube_it
client = YouTubeIt::Client.new
client.video_by_user("chebyte","FQK1URcxmb4")
# with yt

Access control list

While youtube_it allows users to give and revoke permissions to rate, comment, respond, list, embed and syndicate uploaded videos, Yt does not.

The reason is that most of these permissions have been deprecated in YouTube Data API V3. The only parameter that can still be passed when updating a video is 'embeddable'; however many users have reported that updating this setting through the API simply does not work. See https://code.google.com/p/gdata-issues/issues/detail?id=4861

Block users from commenting on a video:

# with youtube_it
client = YouTubeIt::Client.new(:username => "youtube_username", :password =>  "youtube_passwd", :dev_key => "developer_key")
client.video_upload(File.open("test.mov"), :title => "test",:description => 'some description', :category => 'People',:keywords => %w[cool blah test], :comment => "denied")
# with yt: not supported (was removed from YouTube API V3; only the embeddable setting can be specified)

Block users from embedding a video:

# with youtube_it
client = YouTubeIt::Client.new(:username => "youtube_username", :password =>  "youtube_passwd", :dev_key => "developer_key")
client.video_upload(File.open("test.mov"), :title => "test",:description => 'some description', :category => 'People',:keywords => %w[cool blah test], :embed => "denied")
# with yt: not supported (it is documented in YouTube API V3 but looks like it is not working)

Partial updates

While youtube_it uses a separate method to specify that an UPDATE request should not modify any field that has not been explicitly specified, Yt applies this behavior by default

Change the title of a video, but not its privacy status or its description:

# with youtube_it
client = # new client initialized with either OAuth or AuthSub
client.video_partial_update(video_id, :title => 'new title')
# with yt
account = Yt::Account.new access_token: 'access_token'
video = Yt::Video.new id: video_id, auth: account
video.update title: 'new title'
