Hi All
101 Howto for activeyoutube & ruby on rails . I tried to investigate web services and ruby on rails . My simple thought was try to access youtube . So I found activeyoutube (http://www.quarkruby.com/2008/1/15/activeresource-and-youtube , gem version http://www.quarkruby.com/2008/2/12/active-youtube) which I thought to use . I run in a few issues , maybe because I am a Beginner .
First my Installation :
- Ruby on Rails 2.2.2 and 2.3.1
- activeresource 2.2.2 and 2.3.1
- ruby 1.86
As I run into issues I tried both Rails Versions .
Let’s start :
install activeyoutube :
gem install active_youtube
or
sudo gem install active youtube
Create Rails youtube project :
rails youtube
Create Youtube Controller
cd youtube
ruby script/generate controller youtube index
edit app/controllers/youtube_controller.rb
Add Require for activeyoutube to app/controllers/youtube_controller.rb : require ‘active_youtube’
Add Index in the controller : def index , end .
Use the the activeyoutube example in the youtube controller for index :
copy the example section from http://www.quarkruby.com/2008/2/12/active-youtube in your controller (app/controllers/youtube_controller.rb):
app/controllers/youtube_controller.rb :
require ‘active_youtube’
class YoutubeController {:vq => ‘ruby’, :”max-results” => ‘5’})
puts search.entry.length
## video information of id = ZTUVgYoeN_o
vid = Youtube::Video.find(“ZTUVgYoeN_o”)
puts vid.group.content[0].url
## video comments
comments = Youtube::Video.find_custom(“ZTUVgYoeN_o”).get(:comments)
puts comments.entry[0].link[2].href
## searching with category/tags
results = Youtube::Video.search_by_tags(“Comedy”)
puts results[0].entry[0].title
#### STANDARDFEED
## retrieving standard feeds
most_viewed = Youtube::Standardfeed.find(:most_viewed, :params => {:time => ‘today’})
puts most_viewed.entry[0].group.content[0].url
#### USER
## user’s profile – guthrie
user_profile = Youtube::User.find(“guthrie”)
puts user_profile.link[1].href
#### PLAYLIST
## get playlist – multiple elements in playlist
playlist = Youtube::Playlist.find(“EBF5D6DC4589D7B7”)
puts playlist.entry[0].group.content[0].url
end
end
Start the rails :
ruby script/server
Connect to Youtube :
http://localhost:3000/youtube
You might get this error :
ActiveResource::ClientError in YoutubeController#index
Failed with 406 Not Acceptable
Issue Change in activersource from version 2.1.1 ( more info http://rails.lighthouseapp.com/projects/8994/tickets/1053-removed-http-header-accept-by-default)
Fix :
create file lib/connection.rb
file : lib/connection.rb :
module ActiveResource
# overrides the default ActiveResource Connection Class build_request_headers method because of this error:
# http://rails.lighthouseapp.com/projects/8994-ruby-on-rails/tickets/1053-removed-http-header-accept-by-default
class Connection
def build_request_headers(headers, http_method=nil)
authorization_header.update(default_header).update(headers).update(http_format_header(http_method))
authorization_header.update(default_header).update(headers)
end
end
end
Add line on the end connection.rb to your config config/environement.rb
additional line at the end config/environement.rb:
require ‘lib/connection.rb’
Restart Rails :
ruby scribt/server
You might get the next error :
NoMethodError in YoutubeController#index
undefined method `send!’ for Youtube::Video:Class
Issue Ruby 1.8 doesn’t seem to have send! even not all 1.9 Versions ( more Info : http://deaddeadgood.com/2008/11/17/rubys-send-method)
I changed the send! to send /Library/Ruby/Gems/1.8/gems/active_youtube-1.0.0/lib/activeyoutube.rb
New : “#{method_name}#{self.class.send(:query_string, options)}”
Old : “#{method_name}#{self.class.send!(:query_string, options)}”
As I am a beginner there might be a better way , this was my quick and dirty fix .
Restart Rails :
ruby script/server
Connect again with the browser everything seem to work , the requested Info is in shell , not in the browser yet .
