检查是否在 ApplicationController 中进行了身份验证，导致“参数数量错误（给定 1，预期为 0）”

现在我无法导航到我的设计创建的路线/users/edit而不会出现以下错误：

导致错误的方法ApplicationController:authenticate_user!是在让用户进入任何页面之前检查用户是否经过身份验证。我也before_action调用了我所有的控制器到这个方法。

class ApplicationController < ActionController::Base
  protect_from_forgery with: :exception
  before_action :configure_permitted_parameters, if: :devise_controller?
  include Pundit

  layout :layout_by_resource

  protected

  def configure_permitted_parameters
    devise_parameter_sanitizer.permit(:sign_up, keys: [:name])
    devise_parameter_sanitizer.permit(:account_update, keys: [:name])
  end

  #####################################
  # This is what's giving me my error #
  #####################################
  def authenticate_user!
    unless signed_in?
      redirect_to login_path # halts request cycle
    end
  end

  def layout_by_resource
    if devise_controller? && resource_name == :user && action_name == 'new'
      "empty_application"
    else
      "application"
    end
  end

end

我想知道的是为什么我的/users/edit页面在没有其他页面的情况下专门给我这个问题。

我的路线如下所示：

                  Prefix Verb   URI Pattern                    Controller#Action
                    root GET    /                              visitors#index
        new_user_session GET    /users/sign_in(.:format)       devise/sessions#new
            user_session POST   /users/sign_in(.:format)       devise/sessions#create
    destroy_user_session GET    /users/sign_out(.:format)      devise/sessions#destroy
       new_user_password GET    /users/password/new(.:format)  devise/passwords#new
      edit_user_password GET    /users/password/edit(.:format) devise/passwords#edit
           user_password PATCH  /users/password(.:format)      devise/passwords#update
                         PUT    /users/password(.:format)      devise/passwords#update
                         POST   /users/password(.:format)      devise/passwords#create

       user_registration PATCH  /users(.:format)               devise/registrations#update
                         PUT    /users(.:format)               devise/registrations#update
                         DELETE /users(.:format)               devise/registrations#destroy
                         POST   /users(.:format)               devise/registrations#create
              home_index GET    /home/index(.:format)          home#index
              home_minor GET    /home/minor(.:format)          home#minor
                         GET    /                              home#index
                   login GET    /sign-in(.:format)             devise/sessions#new
                    page GET    /pages/*id                     high_voltage/pages#show

我的UsersController.rb看起来像：

class UsersController < ApplicationController
  before_action :authenticate_user!

  def index
    @users = User.all
    authorize User
  end

  def show
    @user = User.find(params[:id])
    authorize @user
  end

  def update
    @user = User.find(params[:id])
    authorize @user
    if @user.update_attributes(secure_params)
      redirect_to users_path, :notice => "User updated."
    else
      redirect_to users_path, :alert => "Unable to update user."
    end
  end

  def destroy
    user = User.find(params[:id])
    authorize user
    user.destroy
    redirect_to users_path, :notice => "User deleted."
  end

  private

  def secure_params
    params.require(:user).permit(:role)
  end

end

我的config/routes.rb看起来像：

Rails.application.routes.draw do
  root to: 'visitors#index'
  devise_for :users


  get "home/index"
  get "home/minor"
  root to: 'home#index'


  devise_scope :user do
    get '/sign-in' => "devise/sessions#new", :as => :login
  end

end

我在我的ApplicationController.authenticate_user!方法中做了什么，不允许我导航到我的/users/edit路线并给我错误，wrong number of arguments (given 1, expected 0)？
