Does anyone know of an easy way to convert a unique
''@username'' (i.e.
@user.username) using an auto_link-esque helper? I have a method for
doing it on the way in to the database but, I realise there''s a few
deal
breakers with that, such as changing the original character length of
whatever was posted (by inserting a href).
Would it be possible to patch auto_link (which I''m already using) to
work with an @username conversion? I was thinking something along these
lines;
# File actionpack/lib/action_view/helpers/text_helper.rb, line 307
307: def auto_link(text, link = :all, href_options = {}, &block)
308: return '''' if text.blank?
309: case link
310: when :all then
auto_link_email_addresses(auto_link_urls(text, href_options, &block),
&block)
311: when :email_addresses then
auto_link_email_addresses(text, &block)
312: when :urls then auto_link_urls(text,
href_options, &block)
###: when :usernames then auto_link_usernames(text,
href_options, &block)
313: end
314: end
I haven''t done any patching or delving in to Rails internals before so
I
don''t how tricky the auto_link_usernames method would be, or, if
there''s
a better way. Any suggestions?

I''d also worry about getting the scanning text for usernames bit right first before wiring it into auto_link Fred --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I do have the scanning working just fine on the way in to the database but, the problem is that auto_link doesn''t ''auto link'' links preceded with @ - if it did, I would already have a working solution (at least, if I was happy with the conversion being done on the way in to the database). Either way, considering what needs to happen in this particular application, the conversion is better-off being done in the view and probably in tandem with auto_link (seeing as auto_link already does the job just fine on ''@comment.body'' - with everything but @usernames). I know little about alias_method_chain - am I right in presuming that it allows behavior to be added without ''overwriting'' a method? Where would the alias_method_chain live? Also, a little OT; I came across a link to your company site a little while back and realised you''re based in Cambridge (IIRC). Do you get to (or know of?) many Rails/web app meet-ups? I''m in lovely Stratford-Upon-Avon. There doesn''t appear to be much in the way of meet-ups around here. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
