Rails - Oct 2007 - automatic form tag helpers given the attribute type.

Hi. I need to get the apropiate tag helper given a resource attribute.
I''m pretty much sure rails already has something to do this, but i
don''t
remember where. My ugly solution is this:

    def standard_form_method form, resource, attribute
      case resource.column_for_attribute(attribute).type
      when :text
        form.text_area(attribute)
      when :binary, :boolean
        form.check_box(attribute)
      else
      #when :string, :integer, :float, :decimal
      #when :datetime, :timestamp, :time, :date
        form.text_field(attribute)
      end
    end

then in erb you can call, inside a form

(EDIT.RHTML)

<% form_for :resource,
            :url => resource_path(@resource),
            :html => { :method => :put } do |f| -%>

  <% @resource.each_attribute do |attribute| -%>
    <% ar_form_method(f, @resource, attribute) -%>
  <% end -%>
  <%= submit_tag "Send" %>
<% end %>
