In the specific case of a Rails action (as opposed to the general case of getting the current method name) you can use params[:action]
在 Rails 操作的特定情况下（与获取当前方法名称的一般情况相反），您可以使用 params[:action]
Alternatively you might want to look into customising the Rails log format so that the action/method name is included by the format rather than it being in your log message.
或者，您可能希望研究自定义 Rails 日志格式，以便操作/方法名称包含在格式中，而不是包含在日志消息中。

I just did the same. I did it in helper controller, my code is:
我只是做了同样的事情。我是在辅助控制器中完成的，我的代码是：
def get_controller_name
controller_name
end
def get_action_name
action_name
end
These methods will return current contoller and action name. Hope it helps
这些方法将返回当前控制器和操作名称。希望能帮助到你
