Twitter gem user timeline link_to helper for hashes

Hi all,
I just installed the Twitter gem and created a partial where I can
publish my latest tweets. Because the output
is plain text I created an application helper which should replace the
hash tags into some links.

First of all is this a convenient way or is there even a better solution
like build in link to helper or something like that (couldn’t find
anything so far).

My second question is regards my helper function. I had a solution which
was working but the code sucked:

def change_hashes
hashes = text.scan(/#\d*\w*/)
hashes.each do |hash|
text = sanitize(text.gsub(hash, link_to(hash,
https://twitter.com/#!/search/#{hash.sub(/#/, “%23”)}”)))
end
return text
end

So I refactored it into this:

def change_hashes(text)
text.gsub(/#\d*\w*/) { |s| text.sub(s, link_to(s,
https://twitter.com/#!/search/#{s.sub(/#/, “%23”)}”)) }
end

The problem is that if I the tweet contains more than one hash the whole
tweet is being duplicated. Maybe someone can pinpoint me into the right
direction?

Cheers
Greg
