Rails - Oct 2009 - nested_attributes

I have a user object, and a user_profile object.

In my form I have:

<% form_for(:user, :url => object_url, :html => { :method => :put })
do |f| %>
<% f.fields_for :user_profile do |profile_form| %>

      <div>
      <%= profile_form.label :first_name, t("first_name")
%><br />
      <%= profile_form.text_field :first_name %>
      </div>

      <div>
      <%= profile_form.label :last_name, t("last_name") %><br
/>
      <%= profile_form.text_field :last_name %>
      </div>
<% end %>

...


In my model:

class User < ActiveRecord::Base
  has_one :user_profile
  accepts_nested_attributes_for :user_profile
 
attr_accessible :email, :password, :password_confirmation, :user_profile,
:user_profile_attributes

And my controller is using the resource_controller plugin.

When I go to do an update, I''m getting:

ActiveRecord::AssociationTypeMismatch (UserProfile(#2197780400)
expected, got HashWithIndifferentAccess(#2159358740))

Here''s my data:

Parameters: {"action"=>"update",
"_method"=>"put",
"authenticity_token"=>"tkMl1SIlEf2s6wV60cAL/J7hOF2ql614cwWuI4da5lg=",
"id"=>"1",
"controller"=>"admin/users",
"user"=>{"user_profile"=>
{"last_name"=>"asdf",
"first_name"=>"asdf"},
"password_confirmation"=>"[FILTERED]",
"role"=>{"admin"=>"1",
"user"=>"1"},
"password"=>"[FILTERED]",
"email"=>"asdf-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org"}}

I think the parameter key for updating the user_profile relation
should be user_profile_attributes, I''m not sure why the fields_for
call is generating it without the suffix. Have you checked the bug
tracker? I would test it without the attr_accessible call as well.

Hope that helps,
Andrew
