Question

我正在尝试使用活动的admin和formtastic来创建一个表单，在该表单中，可以在单独的面板上编辑特定类型的评论，目前，我通过.html.erb部分渲染面板，如下所示：

<div class="panel">
  <h3>Admin Reviews</h3>
  <div class="panel_contents">
    <div>
      <% f.has_many :reviews, heading: false, new_record: true, allow_destroy: false do |review| %>
        <% next unless review.object.reviewer_type === "Admin" %>
        <%= render partial: "admin/admin_reviews", locals: { r: review } %>
        <% review.input :_destroy, :as => :boolean, :label => "Delete" %>
      <% end %>
    </div>
  </div>
</div>

<div class="panel">
  <h3>Reviews</h3>
  <div class="panel_contents">
  <div>
    <% f.has_many :reviews, heading: false, new_record: true, allow_destroy: false do |review| %>
       <% next if review.object.reviewer_type === "Admin" %>
       <%= render partial: "admin/form_reviews", locals: { r: review } %>
       <% review.input :_destroy, :as => :boolean, :label => "Delete" %>
    <% end %>
  </div>
</div>

但是我宁愿做一些事情来摆脱空白的div，该空白的div是每个迭代的评论的迭代结果，该评论属于另一个面板（blank div）：

<div class="panel">
  <h3>Admin Reviews</h3>
  <div class="panel_contents">
    <div>
      <% admin_reviews = Review.where(reviewer_type: "Admin") %>
      <% f.has_many admin_reviews, heading: false, new_record: true, allow_destroy: true do |review| %>
        <%= render partial: "admin/admin_reviews", locals: { r: review } %>
      <% end %>
    </div>
  </div>
</div>

<div class="panel">
  <h3>Reviews</h3>
  <div class="panel_contents">
  <div>
    <% reviews = Review.where.not(reviewer_type: "Admin") %>
    <% f.has_many reviews, heading: false, new_record: true, allow_destroy: true do |review| %>
       <%= render partial: "admin/form_reviews", locals: { r: review } %>
    <% end %>
  </div>
</div>

上面的方法不起作用，但是我希望它能传达出我对一个整洁的解决方案的需求，该解决方案没有我正在考虑使用javascript隐藏的空白div。

<div class="panel">
  <h3>Reviews</h3>
    <div class="panel_contents">
      <div>
        <% f.has_many :reviews, for: [:reviews, f.object.non_admin_reviews], heading: false, new_record: true, allow_destroy: true do |review| %>
          <%= render partial: "admin/tutors/form_tutor_reviews", locals: { r: review } %>
        <% end %>
     </div>
   </div>
</div>

Active Admin表单：has_many按条件在单独的面板中输入
