Topic: Formtastic and nested fields

Hi all,
I hope to finad a solution to my problem in this forum.

I have a formtastic form that should let me add many pictures to an article (very schoolchildren task)

I have an Article model:

class Article < ActiveRecord::Base
  has_many :pictures
  accepts_nested_attributes_for :pictures
  attr_accessor :filename

And I have a Picture model:

class Picture < ActiveRecord::Base
  belongs_to :article    

This is my form-whosaid?-tastic  form, I followed as much as possible the official documentation

<%= semantic_form_for [:admin, @article] do |f| %>
  <%= f.inputs "Description" do %>
    <%=f.input :description %>
  <% end %>

  <%= f.inputs "Gallery" do %>
          <%= f.semantic_fields_for :picture do |picture| %>
            <%= picture.input :filename %>
          <% end %>
  <% end %>

  <%= f.actions %>
<% end %>

The problem is when I submit I get this message:

unknown attribute: picture

What's wrong? singular and plurals should be ok, or not?

Thanks to all.
