Rails3 Client Side Validation Issue

Have been watching Ryan's excellent screencasts and on this episode (#263 client_side_validations) he says to add the following line of code in the _form.html.erb file:

<%= form_for @user, :validate => true do |f| %>

However, if users have Devise installed they will be putting the code into the new.html.erb file where the following code is already installed at the top which creates an error:

<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name))     do |f| %>

Any ideas on how to get this working?

Thx.

Try this:

<%= form_for(resource, :validate => true, :as => resource_name, :url => registration_path(resource_name))     do |f| %>
