    <p>I have 3 models; Quote, Item, and Product.</p> <p>My quote/new.html.erb is set up to render a partial which contains the item form, and in that item form a partial is rendered to choose a product.</p> <p>the error: ActiveModel::MassAssignmentSecurity::Error in QuotesController#create "Can't mass-assign protected attributes: products"</p> <p>(I edited out irrelevant stuff in the following) Quote.rb</p> <pre><code>class Quote &lt; ActiveRecord::Base attr_accessible :items_attributes has_many :items, :dependent =&gt; :destroy accepts_nested_attributes_for :items end </code></pre> <p>Item.rb</p> <pre><code>class Item &lt; ActiveRecord::Base attr_accessible :price, :product_attributes belongs_to :quote belongs_to :product accepts_nested_attributes_for :product end </code></pre> <p>Product.rb</p> <pre><code>class Product &lt; ActiveRecord::Base attr_accessible :name, :item_make has_many :items accepts_nested_attributes_for :items end </code></pre> <p>new.html.erb</p> <pre><code>&lt;%= simple_nested_form_for @quote do |m| %&gt; &lt;%= m.simple_fields_for :items, :html =&gt; { :multipart =&gt; true } do |quoteform| %&gt; &lt;%= render "form", f: quoteform %&gt; &lt;% end %&gt; &lt;%= m.link_to_add "Add an item", :items %&gt; &lt;%= m.button :submit %&gt; &lt;% end %&gt; </code></pre> <p>_form.html.erb</p> <pre><code>&lt;%= f.simple_fields_for :products, :html =&gt; { :multipart =&gt; true } do |x| %&gt; &lt;% render "layouts/styleselect", g: x %&gt; &lt;% end %&gt; </code></pre> <p>_styleselect.html.erb</p> <pre><code>&lt;% g.hidden_field :item_make, :value =&gt; @item.make %&gt; &lt;%= g.input :name, collection: Product.where(:item_make =&gt; 1), label: false, input_html: {:id=&gt;"sst_style"} %&gt; </code></pre> <p>So basically the nested form goes Quote->Item->Product, but item belongs to product, which maybe is causing the problem? I tried adding product_attributes or products_attributes to both the item model and the quote model, and the same with accepts_nested_attributes_for product(s). </p> <p>Any help would be appreciated, thanks.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
