Question

I know it’s supposed to be easy, but I just can’t figure out how to modify an existing auto_html filter to get the output I need. I found this Creating filters for auto_html
but I need to modify an existing filter.

for example, I have a list of youtube links in the db in this format (http://youtu.be/UfQC1h-EANI) and printed out in my view:

%li
  = link_to link.title, link.url, :class => "youtube title_link"

When the the link is clicked, I need the http://youtu.be/UfQC1h-EANI converted to http://www.youtube.com/embed/UfQC1h-EANI?rel=0

I’ve managed to get a conversion working using auto_html, however, it’s coming with all of the html attached to it. I’m thinking if I can modify the filter, I can adjust it to just give me the url without all the html. I can’t for the life of me figure out how to modify auto_html’s youtube filter. Is this even the best approach for this?

Any help is muchly appreciated!

Answer 1

Just do it with regex

link_to link.title, "http://youtube.com/embed/#{link.url.to_s.match(/\/\/youtu.be\/(\S+)$/)[1]}/?rel=0", :class => "youtube title_link"

If you want it onclick only, you can do it in JavaScript.
