Converting a regular Youtube 'link' into an embedded video

Question

My goal: I am trying to allow users to embed a link to a Youtube video in my site, while giving me control over the player\'s settings.

I would like to do this by only a

Answer 1

something like this (for ex. in model):

@@video_regexp = [ /^(?:https?:\/\/)?(?:www\.)?youtube\.com(?:\/v\/|\/watch\?v=)([A-Za-z0-9_-]{11})/, 
                   /^(?:https?:\/\/)?(?:www\.)?youtu\.be\/([A-Za-z0-9_-]{11})/,
                   /^(?:https?:\/\/)?(?:www\.)?youtube\.com\/user\/[^\/]+\/?#(?:[^\/]+\/){1,4}([A-Za-z0-9_-]{11})/
                   ]

def video_id
  @@video_regexp.each { |m| return m.match(source_url)[1] unless m.nil? }
end

where source_url is the full link to video. then a helper:

def youtube_video(video_id)
  render :partial => 'youtube_video', :locals => { :id => video_id }
end

and sample partial (haml):

%iframe{:allowfullscreen => "", :frameborder => "0", :height => "349",
        :src => "http://www.youtube.com/embed/#{id}", :width => "560"}

and in view as simple as:

= youtube_video Model.video_id
