form_for and FormBuilder

[walt]

Hi Ian,

In my lib/ I have an extended_layout_form_builder.rb that I use(d with
resource_controler) on the detail forms like this:

f.render_associated_form(@invoice.invoice_items, :new => 1, :builder
=> ExtendedLayoutFormBuilder)

or, on the many form like this:

<% extended_layout_form_for(:project, :html => { :class =>
"wufoo" }, :url => projects_url) do |f| %>

I've enclosed the contents of my extended formbuilder below.

My question is - how can I make form_for_resource play nice with my
extended layout formbuilder?

(I am aware, that the detail form - render_associated_form - part will
not "fly" with resources_controller, but I sure would like the main
forms to use the extended formbuilder) <:)

Cheers,
walt

Hi Ian,

well - it's kind of a hack, I think - but here's how I've solved it
(at least for now) :)

<%
extended_layout_form_for( resource.class.name.underscore.to_sym, :html
=> { :class => "wufoo" }, :url => resources_url) do |f| %>

> <% extended_layout_form_for(:project, :html => { :class => "wufoo" }, :url => projects_url) do |f| %>
>

Cheers,
walt
