Hi, in my app, using the error_message_on form helper like this: <label for="user_name">User name:</label> <%= error_message_on ''user'', :name %> <%= f.text_field :name %> generates the following error: undefined method `errors'' for :user:Symbol I am using edge revision 5813 and the simply_helpful plugin. Is there a way to fix this?

Hi, I have this very normal link_to call: <%= link_to name, tag_path(name) %> The ''name'' can be something like "ASP.NET".
