    <p>I have been following Ryan Bates' tutorial on nested forms <a href="http://railscasts.com/episodes/196-nested-model-form-part-1?view=asciicast" rel="nofollow">Railscast 196</a></p> <p>The form for the new action shows the nested attributes for quizzes but does not show nested attributes for the key. I am guessing this is because quizzes have a has_many relationship where key has a has_one relationship... But I cannot figure out what I'm doing wrong?</p> <p>Any help is much appreciated!</p> <p>This is my model:</p> <pre><code>class Repository &lt; ActiveRecord::Base has_many :quizzes, :dependent =&gt; :destroy has_one :key, :dependent =&gt; :destroy accepts_nested_attributes_for :key, :quizzes end </code></pre> <p>This is my controller:</p> <pre><code>def new @repository = Repository.new 3.times { @repository.quizzes.build } @repository.key = Key.new respond_to do |format| format.html # new.html.erb format.xml { render :xml =&gt; @repository } end end </code></pre> <p>This is my view:</p> <pre><code>&lt;div class="field"&gt; &lt;%= f.label :wp_uid %&gt;&lt;br /&gt; &lt;%= f.text_field :wp_uid %&gt; &lt;% f.fields_for :quizzes do |quiz_fields| %&gt; &lt;p&gt; &lt;%= quiz_fields.label :name, "Name" %&gt;&lt;br /&gt; &lt;%= quiz_fields.text_field :name %&gt; &lt;/p&gt; &lt;% end %&gt; &lt;% f.fields_for :key do |key_fields| %&gt; &lt;div class="field"&gt; &lt;%= key_fields.label :value, "Value" %&gt;&lt;br /&gt; &lt;%= key_fields.text_field :value %&gt; &lt;/div&gt; &lt;div class="field"&gt; &lt;%= key_fields.label :expiry, "Expiry" %&gt;&lt;br /&gt; &lt;%= key_fields.date_select :expiry %&gt; &lt;/div&gt; &lt;% end %&gt; &lt;/div&gt; &lt;div class="actions"&gt; &lt;%= f.submit %&gt; &lt;/div&gt; &lt;% end %&gt; </code></pre>

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.
