rails version 1.0 the same code render :file=>?/spec/comment_list? work will in a .rhtml file while i put it in controller ,it will produce nothing to client browser. it must use options[:use_full_path] to work fine in controller code. after read some rails source code ,i think the reason is below: file action_controller/base.rb line 602 if file = options[:file] render_file(file, options[:status], options[:use_full_path], options[:locals] || {}) while action_view/base.rb has these code at line 223 options[:use_full_path] = options[:use_full_path].nil? ? true : options[:use_full_path] is this a bug ? or designed to it? -- Posted via http://www.ruby-forum.com/.
