現在我無法瀏覽到我的設計創建的路線/users/edit沒有得到以下錯誤：檢查是否驗證在ApplicationController中產生「錯誤的參數數目（1給出，預計0）」

導致錯誤的方法是ApplicationController:authenticate_user!，我在檢查用戶是否經過身份驗證後才讓他們進入任何頁面。我的所有控制器上都有一個before_action調用方法。
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
什麼我不知道是爲什麼我/users/edit頁特別是給了我這個問題，當沒有其他頁面。
我的路線如下所示：
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
cancel_user_registration GET /users/cancel(.:format) devise/registrations#cancel
new_user_registration GET /users/sign_up(.:format) devise/registrations#new
edit_user_registration GET /users/edit(.:format) devise/registrations#edit
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UsersController.rb樣子：
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
而且我的config/routes.rb中樣子：
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
我是什麼doi ng在我的ApplicationController.authenticate_user!方法，不允許我導航到我的/users/edit路線，並給我錯誤，wrong number of arguments (given 1, expected 0)？
你能否提供堆棧跟蹤的錯誤？ –
@IgorDrozdov剛剛添加了堆棧跟蹤。對於那個很抱歉。 – beckah
