    <p>I give up. I'm trying to build a simple nested form with 2 models following Railscasts #196 episode and doesn't work. Can someone send a working example please so I can test on my environment. I'm using 3.1.0</p> <p>For example when I try to build 3 questions on the form only 1 question field appears, then survey_id is never passed across. </p> <p>I would appreciate your help after 2 days and nights on it. I got missing something really big. Thanks</p> <p>Model</p> <pre><code>class Survey &lt; ActiveRecord::Base has_many :questions, :dependent =&gt; :destroy accepts_nested_attributes_for :questions attr_accessible :name, :questions_attributes end class Question &lt; ActiveRecord::Base belongs_to :survey attr_accessible :survey_id, :name end </code></pre> <p>Controller</p> <pre><code>def new @survey = Survey.new 4.times { @survey.questions.build } respond_to do |format| format.html # new.html.erb format.json { render json: @survey } end end def create @survey = Survey.new(params[:survey]) respond_to do |format| if @survey.save format.html { redirect_to @survey, notice: 'Survey was successfully created.' } format.json { render json: @survey, status: :created, location: @survey } else format.html { render action: "new" } format.json { render json: @survey.errors, status: :unprocessable_entity } end end end </code></pre> <p>View</p> <pre><code>&lt;%= form_for(@survey) do |f| %&gt; &lt;% if @survey.errors.any? %&gt; &lt;div id="error_explanation"&gt; &lt;h2&gt;&lt;%= pluralize(@survey.errors.count, "error") %&gt; prohibited this survey from being saved:&lt;/h2&gt; &lt;ul&gt; &lt;% @survey.errors.full_messages.each do |msg| %&gt; &lt;li&gt;&lt;%= msg %&gt;&lt;/li&gt; &lt;% end %&gt; &lt;/ul&gt; &lt;/div&gt; &lt;% end %&gt; &lt;div class="field"&gt; &lt;%= f.label :name %&gt;&lt;br /&gt; &lt;%= f.text_field :name %&gt; &lt;/div&gt; &lt;%= fields_for :questions do |builder| %&gt; &lt;%= builder.label :name, "Question" %&gt; &lt;%= builder.text_field :name %&gt; &lt;% end %&gt; &lt;br /&gt;&lt;br /&gt; &lt;div class="actions"&gt; &lt;%= f.submit %&gt; &lt;/div&gt; &lt;% end %&gt; </code></pre>

    3. COThis looks right to me, have you checked that survey_id column exists in the table questions? Also, watch what happens when you submit the form in the server console.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
