ActiveScaffold and partials
I was thinking of doing partials as I did in the simple Rails
application I worked on today.
But, since I''m using ActiveScaffold, I didn''t find any *.html.erb in the
views folder of the Rails application that I need to make my partials!
How can I work with partials in ActiveScaffold?
Thanks.

link_to problem
hi @ all
I create a new archiv.html.erb and a archiv method in the controller.
Now, I would like to link from index.html.erb to archiv.html.erb. I
tried to use <%= link_to ''archive'', archiv_xxx_path %> but it doesn''t
run.
It appears a error message "SyntaxError in xxx#index".
Does anyone know, how I can enhance this problem?
thanks a lot...
