Ruby on rails Rails 3.2身份验证返回无效的用户名/密码组合

嗨，我最近看了railscast#270（Rails 3.1中的身份验证）。我正在运行3.2 Rails atm。当我注册应用程序时，一切似乎都正常，但当我尝试使用完全相同的用户名和密码登录时，我被拒绝了。代码如下：

# == Schema Information
#
# Table name: users
#
#  id              :integer          not null, primary key
#  username        :string(255)
#  password_digest :string(255)
#  created_at      :datetime         not null
#  updated_at      :datetime         not null
#

User.rb

    class User < ActiveRecord::Base
  attr_accessible :username, :password, :password_confirmation

  # validations

  has_secure_password

  end

ApplicationHelper.rb

module ApplicationHelper
    def current_user
        @current_user ||= User.find(session[:user_id]) if session[:user_id]
    end
end

用户\u controller.rb

class UsersController < ApplicationController
  def new
    @user = User.new
  end

  def create
    @user = User.new(params[:user])
    if @user.save
        redirect_to root_path, :flash => { :success => "Signed Up!" }
    else
        render :new
    end
  end
end

class SessionsController < ApplicationController
  def new
  end

  def create
    user = User.find_by_username(params[:username])
    if user and user.authenticate(params[:password])
        session[:user_id] = user.id
        redirect_to root_path, :flash => { :success => "Signed In! " }
    else
        flash.now[:error] = 'Invalid email/password combination'
        render :new
    end
  end

  def destroy
    session[:user_id] = nil
    redirect_to root_path, :flash => { :success => "Signed Out!" }
  end
end

请向我们显示错误日志。我已使用rails服务器日志进行了更新，这是我唯一能找到的日志My specs return-Failure/error:controller.What_signed_in expected signed_in？要返回true，则得到false 1。从您的日志中，我没有看到任何ruby失败，但是css失败（与引导相关的问题）2。如果您想在rspec中使用登录功能，请使用其官方文档提供的

模拟登录方法

。在开发或生产环境中运行时，这并不能解决我的问题

class SessionsController < ApplicationController
  def new
  end

  def create
    user = User.find_by_username(params[:username])
    if user and user.authenticate(params[:password])
        session[:user_id] = user.id
        redirect_to root_path, :flash => { :success => "Signed In! " }
    else
        flash.now[:error] = 'Invalid email/password combination'
        render :new
    end
  end

  def destroy
    session[:user_id] = nil
    redirect_to root_path, :flash => { :success => "Signed Out!" }
  end
end
