Rails - Apr 2006 - Please help : how to link_to() and css styles ?

Hello, I''m having hard times on a very simple problem : how to provide
a
css class to a link_to tag ?

I''m using this :
<%= link_to ''Cancel'', :action =>
''list'', :class => ''btn-cancel'' %>

and RoR produces this :
<a href="/gallery/list?class=btn-cancel">Cancel</a>


I''ve read the doc of url_for several times but I still don''t
see why it
doesn''t work ?


Thanks

Definition of link_to:

    link_to(title, url, options)

The ruby interpreter thinks that :class belongs to the url. Try:

<%=link_to Cancel, {:action => ''list''}, :class =>
''btn-cancel'' %>

Thanks for the help, it works like a charm but I still don''t understand
why the 3 comma delimited parameters ''Cancel'', :action =>
''list'', :class
=> ''btn-cancel'' does not fit into title, url, options

Why :action => ''list'', :class =>
''btn-cancel'' are interpreted as the
second parameter ? I thought that {:action => ''list'',
:class =>
''btn-cancel''} only would produce that !?

I think it''s because if you don''t put braces around your
parameters, the
method thinks that anything after the first parameter is part of the
second parameter. As a general rule if you have more than 2 parameters
for link_to or the like kind of methods, you should put in braces to
indicate exactly what you want. I believe this is part of Ruby''s
programming idiom.
