I'm working with a similar model in Episode 73, (my scenario is editing multiple pictures for a product using attachment_fu).

And I'm getting an error when I try the technique suggested:

./views/admin/_form.rhtml

<% for picture in product.pictures %>         <% fields_for "product[picture_attributes]", picture do | picture_form| %>         Title: <%= picture_form.text_field :title %> <% end %>

./models/product.rb     def picture_attributes=(picture_attributes)         picture_attributes.each do |attributes|             pictures.build(attributes)         end     end

undefined method `stringify_keys!' for "33":String

Parameters: {"commit"=>"Edit", "product"=>{"image_url"=>"shep.jpg", "price"=>"400.00", "title"=>"German Shepard Lab Mix #2b", "category_ids"=>["6"], "picture_attributes"=>{"33"=>{"title"=>"asdf2"}, "24"=>{"title"=>"asdf"}, "27"=>{"title"=>"asdf"}, "30"=>{"title"=>"asdf"}}, "description"=>"3 year old german shepard lab mix. Test!"}, "id"=>"23", "picture"=>{"uploaded_data"=>""}}

I noticed in the video, it shows the "picture_attributes" parameter as an array (not a hash is it shows on mine).

Nevermind, episode #75 had the solution :slight_smile:
