Question

这是来自users_controller.rb

class UsersController < ApplicationController
  before_action :logged_in_user, only: [:index, :edit, :update, :destroy]
  before_action :correct_user,   only: [:edit, :update]
  before_action :admin_user,     only: [:destroy]
. . .
  def destroy
    User.find(params[:id]).destroy
    flash[:success] = "User deleted"
    redirect_to users_url
  end

我仍然不知道错误在哪里。请问有人可以帮助我吗？感谢。

我已经从控制台附加了日志。我希望这会有所帮助。

我已根据要求添加了日志。

行动“摧毁”＃39;找不到UsersController
