无法为UsersController找到操作'create'

Question

我正在做Michael Hartl的Rails教程的第7章，并且在尝试注册开发中的用户时出现错误。我已经完成了7.3章节，所以我的所有测试都应该现在通过，但我仍然在收到The action 'create' could not be found for UsersController的开发。

这里是我的用户控制器

class UsersController < ApplicationController 

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

    def new 
    @user = User.new 

    def create 
    @user = User.new(user_params) 
    if @user.save 
     flash[:success] = "Welcome to the Sample App!" 
     redirect_to @user 
    else 
     render 'new' 
    end 
    end 

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

在本教程这一点我应该能够登录在线形式提供给用户时没有问题。这是我的github仓库https://github.com/ajhausdorf/sample_app

Answer 1

您的def new尚未关闭。

此代码应工作

class UsersController < ApplicationController 

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

    def new 
    @user = User.new 
    end # Here what you missing 

    def create 
    @user = User.new(user_params) 
    if @user.save 
     flash[:success] = "Welcome to the Sample App!" 
     redirect_to @user 
    else 
     render 'new' 
    end 
    end 

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

end

你end s为走出低谷：

class UsersController < ApplicationController 

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

    def new 
    @user = User.new 
    end # You were missing one here. 

    def create 
    @user = User.new(user_params) 
    if @user.save 
     flash[:success] = "Welcome to the Sample App!" 
     redirect_to @user 
    else 
     render 'new' 
    end 
    end 

    def user_params 
     params.require(:user).permit(:name, :email, :password, 
            :password_confirmation) 
    end 
    # end # You have an extra one here. 
end 

Answer 3

你new方法并没有结束，你认为它结束;它包含了create和user_params方法。

您已经创建了一个名为create内的new方法的本地方法，而不是建立在UserController类称为create一个普通实例方法。

Answer 4

def new 
    @user = User.new 
end # you are missing this line 

def create
