Points to keep in mind
- When using the ActiveResource::CustomMethods (get/post) make sure you are using "find_custom" and not "find"
- Disable the logging of ActiveResource, since the following line leads to exception if logger is enabled.


## line 111, connection.rb
logger.info "--> #{result.code} #{result.message} (#{result.body ? result.body : 0}b %.2fs)" % time if logger

  3. #### Create classes for YouTube resources.
  4. class Video < ActiveYouTube
  5.   self.site = "http://gdata.youtube.com/feeds/api"
  6.  
  7.   ## To search by categories and tags
  8.   def self.search_by_tags (*options)
  9.     from_urls = []
  10.     if options.last.is_a? Hash
  11.       excludes = options.slice!(options.length-1)
  12.       if excludes[:exclude].kind_of? Array
  13.         from_urls << excludes[:exclude].map{|keyword| "-"+keyword}.join("/")
  14.       else
  15.         from_urls << "-"+excludes[:exclude]
  16.       end
  17.     end
  18.     from_urls << options.find_all{|keyword| keyword =~ /^[a-z]/}.join("/")
  19.     from_urls << options.find_all{|category| category =~ /^[A-Z]/}.join("%7C")
  20.     from_urls.delete_if {|x| x.empty?}
  21.     self.find(:all,:from=>"/feeds/api/videos/-/"+from_urls.reverse.join("/"))
  22.   end
  23. end
  24.  
  25. class User < ActiveYouTube
  26.   self.site = "http://gdata.youtube.com/feeds/api"
  27. end
  28.  
  29. class Standardfeed < ActiveYouTube
  30.   self.site = "http://gdata.youtube.com/feeds/api"
  31. end
  32.  
  33. class Playlist < ActiveYouTube
  34.   self.site = "http://gdata.youtube.com/feeds/api"
