form_tag with the new template

Hi,

I am trying to modify the existing template of new provided by rails using form tag

My controller is languages new.html.erb looks like this

<% form_tag :controller=> "languages", :action => "create" do %>          Language <%= text_field_tag "language" %>                        <%= submit_tag "Create" %> <% end %>

Instead of

<% for_for(@language) |f| do %>        Language<%= f.text_field :language %>       <% f.submit "create" %> <% end %>

Any reason this should not route properly. I get a 500 Internal server error?
