/sessions_helper.rb：

module SessionsHelper

    def sign_in(user)
        cookies.permanent[:remember_token] = user.remember_token
        self.current_user = user
    end

    def signed_in?
    !current_user.nil?  
    end

    def current_user=(uaser)
        @current_user = user
    end

    def current_user
        @current_user ||= User.find_by_remember_token(cookies[:remember_token])
    end

end

/sessions_controller.rb

class SessionsController < ApplicationController

    def new

    end

    def create
    user = User.find_by_email(params[:session][:email])
    if user && user.authenticate(params[:session][:password])
        sign_in user
        redirect_to user
    else
        flash.now[:error] = 'Invalid email/password combination'
        render 'new'
        end
    end

    def destroy

    end

end

/routes.rb 文件：

  SampleApp::Application.routes.draw do

  resources :users
  resources :sessions, only: [:new, :create, :destroy]

  root :to => 'static_pages#home'

  match '/help', to: "static_pages#help"

  match '/about', to: "static_pages#about"

  match '/contact', to: "static_pages#contact"

  match '/signup', to: 'users#new'
  match '/signin', to: 'sessions#new'
  match '/signout', to: 'sessions#destroy', method: "delete"

Answer 1

你在这一行有一个错字：

def current_user=(uaser)

它应该是

def current_user=(user)

Answer 2

你有一个错字。改变：

def current_user=(uaser)

到

def current_user=(user)
