I've got an app that's in invite-only beta right now. Problem is, I can't get the invite system to work. :(

On my root page there's a login form (which works just fine), and I'm trying to add a "request invite" form on the same page. I started doing it by putting the form for InviteRequest (ActiveRecord) inside a partial, in the "views" folder for "InviteRequest". The app is definitely calling this partial, but I'm getting the following error:

NoMethodError in User_sessions#new

Showing app/views/invite_request/_new.html.erb where line #2 raised:

undefined method `invite_requests_path' for #<ActionView::Base:0x25b3248>
Extracted source (around line #2):

1: <% @invite_request = InviteRequest.new() %>
2: <% form_for @invite_request do |ir| %>
3:  <%= ir.label :email %>
4:  <%= ir.text_field :email %>
5: <% end %>

I also read through the "Multiple Models in a Form" section of my trusty copy of "Agile Web Development with Rails", about maybe doing this with a "fieldset" tag, but not sure if this is the right approach.

Thx.
