    copied!<p>I had this working fine yesterday, made some changes and I have no idea how I broke it. I'm sure it's a typo somewhere, but I cannot see it.</p> <p>Any changes made to the nested model in the form are just not being saved at all, the development log shows the attributes going through - and they appear to be in the right format, but it's just not updating at all.</p> <p>I have a <code>User</code> model which references_one <code>Biography</code> like so:</p> <pre><code># app/models/user.rb class User include Mongoid::Document include Mongoid::Timestamps field :first_name, :type =&gt; String field :last_name, :type =&gt; String devise :database_authenticatable, :recoverable, :rememberable, :trackable, :validatable references_one :biography accepts_nested_attributes_for :biography #--snip--- end # app/models/biography.rb class Biography include Mongoid::Document include Mongoid::Timestamps field :content, :type =&gt; String field :role, :type =&gt; String field :is_crew, :type =&gt; Boolean referenced_in :user end </code></pre> <p>And finally my form (i'm using simple form here, but for the most part it behaves very similar to formtastic):</p> <pre><code>&lt;%= simple_form_for [:manage, @user], :html =&gt; {:multipart =&gt; true}, :position =&gt; :left do |f| %&gt; &lt;h2&gt;Login details&lt;/h2&gt; &lt;%= f.input :email, :input_html =&gt; {:class =&gt; "text"} %&gt; &lt;%= f.input :first_name, :input_html =&gt; {:class =&gt; "text"} %&gt; &lt;%= f.input :last_name, :input_html =&gt; {:class =&gt; "text"} %&gt; &lt;div class="biography"&gt; &lt;h2&gt;Biography&lt;/h2&gt; &lt;%= f.simple_fields_for :biography do |biography_form| %&gt; &lt;%= biography_form.input :role, :input_html =&gt; {:class =&gt; "text"} %&gt; &lt;%= biography_form.input :content, :as =&gt; :text, :input_html =&gt; {:class =&gt; "textarea"} %&gt; &lt;%= biography_form.input :is_crew, :as =&gt; :boolean %&gt; &lt;%- end -%&gt; &lt;/div&gt; &lt;%= f.submit "Save user", :class =&gt; "submit mid" %&gt; &lt;% end %&gt; </code></pre> <p>And some output from my development log, incase the answers lie there, and I just cant see them:</p> <pre><code> Started POST "/manage/users/john-doe" for 127.0.0.1 at Wed Dec 15 11:42:09 +1100 2010 Processing by Manage::UsersController#update as HTML Parameters: {"commit"=&gt;"Save user", "authenticity_token"=&gt;"44QlHsbKb8Pm91wnxWJa8Y0QsUXDzp/3rVpfs3G1Inc=", "utf8"=&gt;"✓", "id"=&gt;"john-doe", "user"=&gt;{"biography_attributes"=&gt;{"is_crew"=&gt;"0", "role"=&gt;"Tenor", "id"=&gt;"4d080de56a4f1dfe7700000e", "content"=&gt;"John was born on the 1st of January, 1970."}, "last_name"=&gt;"Doe", "first_name"=&gt;"Johnathan", "email"=&gt;"testing@involved.com.au"}} the_idea_of_north_development['users'].find({:_id=&gt;BSON::ObjectId('4d06e6036a4f1dcb1b000001')}, {}).limit(-1) the_idea_of_north_development['users'].find({:slug=&gt;"john-doe"}, {}).limit(-1) the_idea_of_north_development['biographies'].find({"user_id"=&gt;BSON::ObjectId('4d080de06a4f1dfe7700000d')}, {}).limit(-1) the_idea_of_north_development['$cmd'].find({"count"=&gt;"users", "query"=&gt;{:_id=&gt;{"$ne"=&gt;BSON::ObjectId('4d080de06a4f1dfe7700000d')}, :email=&gt;/^testing@involved\.com\.au$/i}, "fields"=&gt;nil}, {}).limit(-1) the_idea_of_north_development['users'].find({"slug"=&gt;"johnathan-doe"}, {}) MONGODB the_idea_of_north_development['users'].update({"_id"=&gt;BSON::ObjectId('4d080de06a4f1dfe7700000d')}, {"$set"=&gt;{"slug"=&gt;"johnathan-doe", "updated_at"=&gt;Wed Dec 15 00:42:09 UTC 2010, "first_name"=&gt;"Johnathan"}}) Redirected to http://lvh.me:3000/manage/users Completed 302 Found in 17ms </code></pre> <p>Any changes to the <code>User</code> model update fine, but changes to the <code>Biography</code> are unsaved.
