What about the expected result and the actual result. If you are getting an error be sure to say what the error is. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Sorry about giving a bad description.
This is the error I get:
SyntaxError in Front#feed
Showing app/views/front/feed.rxml where line #17 raised:
compile error
./script/../config/../app/views/front/feed.rxml:17: parse error,
unexpected tIDENTIFIER, expecting kDO or ''{'' or
''(''
xml.description advert.description + image_tag
url_for_file_column(advert, "image","thumb") unless
url_for_file_column(advert, "image","thumb").nil?
All I want to do is have advert.description and the image in the
description field of the rss feed.
Thanks for replying

You are stringing multiple method calls with arguments together and ruby cant tell what''s a method and what''s an argument. I would write something like this: if file_url = url_for_file_column(...) xml.description(advert.description + image_tag(file_url)) end As a bonus you only call url_for_file_column once. Keeping it a bit DRYer. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Thanks, that works.
