    <p>I have a Rails 3 form (simple_form, really) that has a set of nested attributes:</p> <pre><code>&lt;%= simple_form_for(@user, :url =&gt; the_path(@user)) do |f| %&gt; ... &lt;%= f.simple_fields_for :credit_card do |c| %&gt; &lt;%= c.input :number, :label =&gt; 'Credit card number' %&gt; ... &lt;% end %&gt; ... &lt;% end %&gt; </code></pre> <p>The problem is that the :credit_card attributes belong to the class CreditCard, which is not a model since I'm not storing any of the credit card data in the database. I have that Class defined in /app/models/credit_card.rb like this (per <a href="http://asciicasts.com/episodes/219-active-model" rel="nofollow">this RailsCast</a>):</p> <pre><code>class CreditCard include ActiveModel::Validations include ActiveModel::Conversion include ActiveModel::Naming attr_accessor :number, :expiration_month, :expiration_year, :cvv validates_presence_of :number, :expiration_month, :expiration_year, :cvv def initialize(attributes = {}) attributes.each do |name, value| send("#{name}=", value) end end def persisted? false end end </code></pre> <p>In user.rb, I have this:</p> <pre><code> has_one :credit_card accepts_nested_attributes_for :credit_card </code></pre> <p>When I access the page, I get this error:</p> <pre><code>undefined method `quoted_table_name' for CreditCard:Class </code></pre> <p>Googling that error didn't yield any suggestions. I'm able to create CreditCard objects from Rails Console, but for some reason the Rails form generator isn't seeing the class.</p> <p>I already tried swapping out simple_form_for with form_for (and the related changes), so I don't think it's a simple_form problem.</p>

    1. COWhat does your controller code look like? You won't be able to save a user that has a credit-card... that's where this breaks down.

    2. COI'm not even getting to the save yet. This error appears when you try to load the form. I suppose I'll just have to add some extra form fields that aren't nested.

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.
