Rails - Apr 2008 - RESTful routes: How to code the "create" form correctly

Hi there,

I''ve been trying to fix this for the whole afternoon, but
don''t get it
to work:

I have:

-> Nested RESTful resources/routes like this:

  map.resources :users, :member => { :enable => :put, :view => :get }
do
|users|
    users.resource :account
    users.resources :roles
    users.resources :messages
  end

-> A link on a page (should bring up a form for a new message
"new.html.erb"):

  <%= link_to ''Send a message'',
new_user_message_path(@user, :target_id
=> @member.id) %>

-> The "MessagesController" like this:

  def new
    @target = User.find(params[:target_id])
    @message = Message.new
  end

-> And the message form "new.html.erb" like this:

  <% form_for @message do |f| %>
    <p>
      <label for=''subject''>Subject:</label>
      <%= f.text_field :subject, :focus => true %>
    </p>
    [...etc...]
  <% end %>

...but I get the error:

NoMethodError in Messages#new
  Showing messages/new.html.erb where line #4 raised:
  undefined method `messages_path'' for
#<ActionView::Base:0x554b884>

  Line 4 is: <% form_for @message do |f| %>


As far as I know, with RESTful routes, it''s sufficient to only have the
"@message" in the form header. Rails 2.0 should automatically
understand
that "@message" is a *new* message and therefor redirect me to the
"new"
form, right?

Thank you very much for any hint which could help me get out of the
mess!
Tom

Correct me if I''m wrong, but as far as I know the form_for helper is
not
able to deal with nested resources when used in the super compact 
fashion above. You''re right, Rails knows that it is dealing with a new 
object; however it  tries to use message_path instead of 
user_messages_path(@user) to create the url. This format should work:

  <% form_for :messages, @message,
              :url => user_messages_path(@user) do |f| %>

Cheers,
Jan

.. that should have read "messages_path instead of user_messages_path"
