如何在Admin :: Records＃show？

Question

我已经在我的rails应用程序中安装了活动的admin gem。我很好地整合了我的模型。登录管理员面板并想查看我的记录后，显示此错误。更新和提交按钮时会出现此错误。但在内部文件更新和编辑，没有副作用。

我已将记录与will paginate集成。

我已将此文件添加到/config/initializers/kaminari.rb，但无法解决...

Kaminari.configure do |config|
  config.page_method_name = :per_page_kaminari
end

完整的错误是：

undefined method `total_count' for #<ActiveRecord::Relation []>
Did you mean?  total_entries

提取的来源（第124行）：

122        arel.public_send(method, *args, &block)
123      else
124        super
125      end
126    end
127  end

我已停用有效的管理员评论。以前，默认情况下会在文件中启用注释 /config/initializers/active_admin.rb

# You can completely disable comments:
# config.comments = false

我通过更改代码禁用了有效的管理员评论：

# You can completely disable comments:
config.comments = false

最后摆脱那个错误。 谢谢大家。
