    <p>The two Models (Step contains "accepts_nested_attributes_for") :</p> <pre><code>class Step &lt; ActiveRecord::Base has_many :statements accepts_nested_attributes_for :statements end class Statement &lt; ActiveRecord::Base belongs_to :step end </code></pre> <p>Step Controller, methods new (with @step.statements.build) and create:</p> <pre><code>def new @step = Step.new @step.statements.build respond_to do |format| format.html # new.html.erb format.json { render json: @step } end end def create @step = Step.new(params[:step]) respond_to do |format| if @step.save format.html { redirect_to @step, notice: 'Step was successfully created.' } format.json { render json: @step, status: :created, location: @step } else format.html { render action: "new" } format.json { render json: @step.errors, status: :unprocessable_entity } end end end </code></pre> <p>and the nested form in New view with form_fields for statements:</p> <pre><code>&lt;%= form_for(@step) do |step_form| %&gt; &lt;div class="field"&gt; &lt;%= step_form.label :step_type %&gt;&lt;br /&gt; &lt;%= select("step", "step_type_id", @step_types.collect {|p| [ p.name, p.id ] }, {:include_blank =&gt; true}) %&gt; &lt;/div&gt; &lt;%= step_form.fields_for :statements do |statement_form| %&gt; &lt;div class="field"&gt; &lt;%= statement_form.label :title %&gt;&lt;br /&gt; &lt;%= statement_form.text_field :title %&gt; &lt;/div&gt; &lt;% end %&gt; &lt;div class="actions"&gt; &lt;%= step_form.submit %&gt; &lt;/div&gt; &lt;% end %&gt; </code></pre> <p>when submit the models don't save because: "Statements step can't be blank" (step should be create before...)</p>

    1. COThe problem was the validates. I have this code in Statement Model: #validates validates :step_id, :presence => true with a belongs_to. So I delete the validate and just it is working.

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.
