Сообщение Ajax из _form.html.erb в index.html.erb

Question

У меня проблема с частичным получением данных из моей формы на странице индекса без обновления страницы. Только имя, описание и флажок публикуются.

Для формы:

<%= form_for(@objective) do |form| %>
  <div class="name field">
    <%= form.label :name %>
    <%= form.text_field :name %>
  </div>
  <div class="description field">
    <%= form.label :description %>
    <%= form.text_area :description %>
  </div><br>
  <div class="user field">
    <%= form.label :user_id %>
    <%= form.collection_select :user_id, User.all, :id, :name %>
  </div>
  <div class="date field">
    <%= form.label :due_date %>
    <%= form.date_select :due_date %>
  </div>
  <div class="group field">
    <%= form.label :group %>
    <%= form.collection_select :group_id, Group.all, :id, :name %>
  </div>
  <div class="completed field">
    <%= form.label :completed %>
    <%= form.check_box :completed %>
  </div>
  <div id="post" class="actions">
    <%= form.submit %>

  </div>
  <% end %>

Запрос

  <div id="postResult">
    <td id="postName"></td>
    <td id="postDescription"></td>
    <td id="postUser"></td>
    <td id="postDate"></td>
    <td id="postGroup"></td>
    <td id="postComplete"></td>
  </div>

  <script type="text/javascript" charset="utf-8">
    $(function () {
      $('form').submit(function (event) {
        event.preventDefault();
        const checked = this.completed == true ? 'completed' : ''
        let values = $(this).serialize();
        let posting = $.post('/objectives.json', values);
        posting.done(function (data) {
          let objective = data;

          $("#postName").text(objective["name"])
          $("#postDescription").text(objective["description"])
          $("#postUser").text(objective["user"]["name"])
          $("#postDate").html(objective["due_date"])
          $("#postGroup").text(objective["group_id"])
          $("#postComplete").text(objective["completed"])
          $("form").reset()
        });
      });
    });
  </script>
  </form>

Контроллер

  def create
      @objective = Objective.new(objective_params)
      respond_to do |format|
        if @objective.save
          format.js
          # comment out format.html to resolve 422 error
          #format.html {redirect_to @objective, notice: 'Objective was successfully created.'}
          format.json {render json: @objective}
        else
          format.html {render :new}
          format.json {render json: @objective.errors, status: :unprocessable_entity}
        end
      end
  end
