我有一个像这样的索引页：

def index
    @admin_albums = Admin::Album.unscoped

    respond_to do |format|
      format.html 
      format.json { render json: @admin_albums }
    end
  end

我也有一个破坏行动：

def destroy
    @admin_album = Admin::Album.unscoped.find(params[:id])


    @admin_album.destroy



    respond_to do |format|
      format.html { redirect_to admin_albums_path }
      format.json { head :no_content }
    end
  end

和一个索引视图：

<% @admin_albums.each do |admin_album| %>
  <tr>
    <td><%= admin_album.admin_style.nom %></td>
    <td><%= admin_album.titre %></td>
    <td><%= admin_album.artiste %></td>
    <td><%= truncate(admin_album.critiques, :length => 255).html_safe %></td>
    <td><%= oui_non(admin_album.public) %></td>
    <td><%= link_to 'Voir', admin_album %></td>
    <td><%= link_to 'Modifier', edit_admin_album_path(admin_album) %></td>
    <td><%= link_to 'Supprimer', admin_album, method: :delete, data: { confirm: 'Êtes-vous sûr ?' } %></td>
  </tr>
<% end %>

问题是：当我点击“Supprimer”来删除一个条目时，我被重定向到索引页面，并且该条目仍然出现在页面上。但是它在数据库中被很好地删除了！这怎么可能 ？

如果我刷新页面，条目仍然存在！我必须等待几分钟，该条目才会在索引页面上消失。

在日志中，似乎忽略了请求“Admin::Album.unscoped.all”，您可以看到它：

编辑：销毁日志中的操作：

问题出在哪里 ？有人有想法吗？
