如何在 Admin::Records#show 中的活动管理员 rails 应用程序 NoMethodError 中消除此错误？
How can I get rid of this error in active admin rails app NoMethodError in Admin::Records#show?
我已经在我的 rails 应用程序中安装了 active admin gem。我很好地融入了我的模型。在我登录到管理面板并想查看我的记录后，它显示了这个错误。此错误出现在更新和提交按钮时。但是在内部更新和编辑文件，没有副作用。
我已经将我的记录与 will paginate 整合在一起。
我也已将此文件添加到我的 /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

错误截图为：
我已经禁用了活跃的管理员评论。以前，默认情况下在文件中启用注释
/config/initializers/active_admin.rb
# You can completely disable comments:
# config.comments = false
我通过更改代码禁用了活跃的管理员评论：
# You can completely disable comments:
config.comments = false
终于摆脱了那个错误。
谢谢大家
我已经在我的 rails 应用程序中安装了 active admin gem。我很好地融入了我的模型。在我登录到管理面板并想查看我的记录后，它显示了这个错误。此错误出现在更新和提交按钮时。但是在内部更新和编辑文件，没有副作用。

错误截图为：
我已经禁用了活跃的管理员评论。以前，默认情况下在文件中启用注释
/config/initializers/active_admin.rb
# You can completely disable comments:
# config.comments = false
我通过更改代码禁用了活跃的管理员评论：
# You can completely disable comments:
config.comments = false
终于摆脱了那个错误。 谢谢大家
