Answer 1

を取得しています余分な<% end %>を追加し、フォームが<%= form ..... %>ない<% form .... %>

これを使用して上記のコードを交換してくださいする必要があります。

<%= form_for @goal do |goal_form| %> 
    <div> 
    <%= goal_form.label :Goal, 'Goal:' %> 
    <%= goal_form.text_field :Goal %> 
    </div> 
    <div> 
    <%= goal_form.label :Description, 'Description:' %> 
    <%= goal_form.text_area :Description %> 
    </div> 
    <div> 
    <%= goal_form.label :Date, 'Date:' %> 
    <%= goal_form.date_select :Date %> 
    </div> 
    <div> 
    <%= goal_form.label :DueDate, 'DueDate:' %> 
    <%= goal_form.date_select :DueDate %> 
    </div> 

    <!-- Here we call fields_for on the project_form builder instance. 
     The block is called for each member of the tasks collection. --> 
    <% goal_form.fields_for :steps do |step_form| %> 
    <p> 
    <div class="field"> 
     <%= step_form.label :requirement %><br> 
     <%= step_form.text_field :requirement %> 
    </div> 

    <div class="field"> 
     <%= step_form.label :completionTime %><br> 
     <%= step_form.number_field :completionTime %> 
    </div> 

    <% unless step_form.object.new_record? %> 
     <div> 
     <%= step_form.label :_delete, 'Remove:' %> 
     <%= step_form.check_box :_delete %> 
     </div> 
    <% end %>
