Suppose a user submits a url: http://www.nyt.com/education/2345545. How can this be shortened to a cleaner url, like nyt.com? -- Posted via http://www.ruby-forum.com/.
require ''uri''
uri = URI.parse("http://www.ruby-lang.org/")
p uri
# => #<URI::HTTP:0x202281be URL:http://www.ruby-lang.org/>
p uri.scheme
# => "http"
p uri.host
# => "www.ruby-lang.org"

So I include the require ''uri'' in the model. Then it seems I need to parse the host part of the uri. How do I parse this? Do I need to use a RegExpression? -- Posted via http://www.ruby-forum.com/.
Sean, Are you saving this url to the model? I''m not sure what you mean by shorten it up? --Tom On May 28, 8:16 am, Sean Six <rails-mailing-l...-ARtvInVfO7ksV2N9l4h3zg@public.gmane.org> wrote:> Mukund wrote: > > require ''uri'' > > > uri = URI.parse("http://www.ruby-lang.org/") > > p uri > > # => #<URI::HTTP:0x202281be URL:http://www.ruby-lang.org/> > > p uri.scheme > > # => "http" > > p uri.host > > # => "www.ruby-lang.org" > > >http://www.ruby-doc.org/core/classes/URI.html > > This is a little harder than I expected.

After they submit the link I want to parse it to the homepage url. Like if the article is www.nyt.com/sports/lakers/123. I want to have this shortened to the homepage link nyt.com. You can try it in the interpreter as someone posted above. -- Posted via http://www.ruby-forum.com/.
Yeah, URI is the library to work with. You could tighten it up and
just do:
homepage = URI.parse("http://www.nyt.com/sports/lakers/123/").host
On the model, you could put "require ''uri'' " but I
think its loaded
with Rails by default.
--Tom
I don''t think

I have @article.url and I want to parse that url. When I tried: @homepage = URI.parse(@article.url).host in the controller I simply got a blank output. -- Posted via http://www.ruby-forum.com/.
Can you post a sample @article.url that results in blank .host output from URI.parse? -----Original Message----- From: rubyonrails-talk-/JYPxA39Uh5TLH3MbocFFw@public.gmane.org [mailto:rubyonrails-talk@googlegroups.com] On Behalf Of Sean Six Sent: Thursday, May 28, 2009 8:53 PM To: rubyonrails-talk-/JYPxA39Uh5TLH3MbocFFw@public.gmane.org Subject: [Rails] Re: shorten a link I have @article.url and I want to parse that url.
