Hi,
Can someone tell me why the following isn't setting an instance variable?
Perhaps they can't be set/used in helpers? I have a revision_info method in
ApplicationHelper that returns the current SVN revision number (used for
debugging info in the footer):
module ApplicationHelper
def revision_info
logger.info("In revision_info(); rev...@rev}") # @rev is always nil
if (@rev ||= (capistrano_revision_info || svn_revision_info)).blank?
return nil
else
return 'Revision ' + @rev
end
end
end
# capistrano_revision_info returns the revision number from the REVISION
file
# capistrano_revision_info returns the revision number from `svn info --xml`
Thanks in advance for any replies.
Cheers,
Lee
