如何显示有多少在Rails控制器和模板中?

class Reflection < ApplicationRecord
    has_many :comments
end


class Comment < ApplicationRecord
    belongs_to :reflection
end

我有一个应用程序,其中反射有任何评论。

在反射的索引视图中,我希望显示每个反射拥有的注释数,并显示每个反射的注释,但我无法确定如何执行此操作。

我试图理解反射索引控制器和模板(index.html.erb代表反射)中要包含什么代码。有什么建议吗?

我可以使用下面的代码在反射控制器中显示单个反射的注释,但也许有更好的方法在Rails中实现这一点。

  def show
    @comments = Comment.where(reflection_id: @reflection.id)
  end

I tried 

  <tbody>
    <% @reflections.each do |reflection| %>
      <tr>
        <td><%= reflection.id %></td>
        <td><%= reflection.reflection %></td>
        <td><%= reflection.user_id %></td>
        <td>
//LOOPING THROUGH COMMENTS IN EACH REFLECTION
        <td><%= reflection.comments.each do |comment| %>
              <%= comment.comment %>, 
            <% end %>
        </td>
//END LOOPING THROUGH COMMENTS IN EACH REFLECTION
        </td>
        <td><%= link_to 'Show', reflection %></td>
        <td><%= link_to 'Edit', edit_reflection_path(reflection) %></td>
        <td><%= link_to 'Destroy', reflection, method: :delete, data: { confirm: 'Are you sure?' } %></td>
      </tr>
    <% end %>
  </tbody>


The above yields the comment but also the objects afterwards:

    fdsafdsa, fdsacdxzdv, [#<Comment id: 8, comment: "fdsafdsa", created_at: "2019-08-27 04:13:34", updated_at: "2019-08-27 04:13:34", reflection_id: 1, user_id: 1>, #<Comment id: 9, comment: "fdsacdxzdv", created_at: "2019-08-27 04:32:36", updated_at: "2019-08-27 04:32:36", reflection_id: 1, user_id: 1>]
