Ok, I am interfacing with the del.icio.us API and I want to collect the
links in an @instance variable for my view. But I''m having trouble with
that part. Here''s what I have:
def get_authenticated(path, http)
request = Net::HTTP::Get.new(path)
request.basic_auth ''user'', ''pass''
response = http.request(request)
response.value
response.body
end
@links = Array.new
http = Net::HTTP.new(''api.del.icio.us'', 443)
http.use_ssl = true
http.start do |http|
xml = get_authenticated(''/v1/posts/recent?count=10'', http)
REXML:ocument.new(xml).root.get_elements(''post'') .each do
|post|
link = post.attributes[''href'']
@links = link
end
end
See where I''m saying "@links = link"? I''m trying to
get that into an
array. Then iterate over the array in the view, but it''s not working.
It
only displays the last of the 10 links returned. Can someone please help
with this???
Thanks a lot!!!

Oh yeah, and I''ve also tried "@links[i] = link" and then "i++" to go to the next index. Not working still. -- Posted via http://www.ruby-forum.com/.
i would try changing link = post.attributes[''href''] to @links = post.attributes[''href''] i think that would work, but i''m not a genius, clearly. -- Posted via http://www.ruby-forum.com/.

Still only displays the last one out of the ten links. Isn''t there a way to "collect" the links? Such as ".collect{post.attributes[''href'']}"? I''ve tried variations of this, but couldn''t get anything to work out. So, I''m still stuck. -- Posted via http://www.ruby-forum.com/.
@links = []
REXML:ocument.new(xml).root.get_elements(''post'') .each do
|post|
link = post.attributes[''href'']
@links << link
end

So i++ should do some weird things but probably won''t throw an error. The << is equivalent to Array.push in other languages if that helps you understand at all. In ruby it seems like counter variables are largely unused which is a mammoth change but it''s really exciting once you really get into the language. Cheers, Chuck Vose

And your domainname is awesome! Why is it that Rails app names so often start with a number though?
