Rails - Mar 2006 - HELP with redirect_to!

I''m having trouble redirecting back to the same page after a comment is
posted.  To post a comment, this is what I''m doing:

#controller
def comments
    content = Content.find(params[:id])
    comment = Comment.new(params[:comment])
    content.comments << comment
    content.save
    redirect_to (
      :action => ''individual'',
      :year => content.posted_at.year,
      :month => content.posted_at.month,
      :day => content.posted_at.day,
      :permalink => content.permalink   # line 61
    )
end

I''m getting a syntax error on line 61.  How can I redirect back to the 
same page?

I''ve tried "redirect_to action => :back" and
"redirect_to
request.request_uri" but neither one of them work.

Please help!
