Ruby on rails RubyonRails Michael Hartl错误：用户页面使用有效信息的注册页面应创建一个用户

我正在学习Michael Hartl关于Ruby on Rails第7章的课程。我已经读完了第七章，并一步一步地跟着读。然而，我也有一些错误，但我不确定我错过了什么

Failures:

  1) User pages signup page with valid information should create a user
     Failure/Error: expect { click_button submit }.to change(User, :count).by(1)
     ArgumentError:
       wrong number of arguments (0 for 1)
     # ./app/controllers/users_controller.rb:24:in `user_params'
     # ./app/controllers/users_controller.rb:12:in `create'
     # ./spec/requests/user_pages_spec.rb:36:in `block (5 levels) in <top (required)>'
     # ./spec/requests/user_pages_spec.rb:36:in `block (4 levels) in <top (required)>'

  2) User pages signup page with invalid information should not create a user
     Failure/Error: expect { click_button submit }.not_to change(User, :count)
     ArgumentError:
       wrong number of arguments (0 for 1)
     # ./app/controllers/users_controller.rb:24:in `user_params'
     # ./app/controllers/users_controller.rb:12:in `create'
     # ./spec/requests/user_pages_spec.rb:23:in `block (5 levels) in <top (required)>'
     # ./spec/requests/user_pages_spec.rb:23:in `block (4 levels) in <top (required)>'

用户\u controller.rb

class UsersController < ApplicationController

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

  def new
    @user = User.new
  end

  def create 
    @user = User.new(user_params)
    if @user.save
        flash[:sucess] = "You've successfully created your account!"
        redirect_to @user
    else
        render 'new'
    end
  end

  private

    def user_params
        params.require.(:user).permit(:name, :email, :password, :password_confirmation)
    end
end

---

前面有一个额外的点：user.permit，它不应该出现在users\u controller.rb文件底部的user\u参数中

试试这个

private

def user_params
  params.require(:user).permit(:name, :email, :password, :password_confirmation)
end

非常感谢你抓住了这个机会。另外，您可能不知道为什么我不能使用注册页面创建任何帐户？当我创建一个新帐户时，什么也没有发生。我注意到你的flash消息只有一个c成功，只有一个提示。当您尝试创建用户时会发生什么？你有错误吗？什么都没发生？谢谢你。我编辑了文件，但没有解决我遇到的问题。当我尝试使用正确的信息创建帐户时，不仅没有创建帐户，而且我也看不到任何消息。当我单击submit时，它会返回到usernew页面。我不确定哪里出了问题以及如何修复它，但现在我可以创建一个用户帐户了。谢谢你的帮助！
