似乎我搞砸了一些东西，我不确定它是什么！但它不工作，因为它应该工作
最初我试图实现一个记住我的框，但它需要一个旋转，现在如果我编辑客户详细信息并更新它，那么我会自动注销。不知道为什么会这样，但这里有一个片段
类客户控制器 < 应用控制器
def index
@customers = Customer.all
end
def new
@customer = Customer.new
end
def show
@customer = Customer.find(params[:id])
@posts = @customer.posts
end
def create
@customer = Customer.new(params[:customer])
if @customer.save
sign_in @customer
flash[:success] = "Welcome to Where you Where!"
redirect_to @customer
else
render 'new'
end
end
def edit
@customer = Customer.find(params[:id])
end
def update
if @customer.update_attributes(params[:customer])
flash[:success] = "Profile Updated"
redirect_to @customer
else
render 'edit'
end
end
def destroy
Customer.find(params[:id]).destroy
redirect_to root_path
end
private
def current_customer?(customer)
customer == current_customer
end
def correct_customer
@customer = Customer.find(params[:id])
redirect_to(root_path) unless current_customer?(@customer)
end
def admin_customer
redirect_to(root_path) unless current_customer && current_customer.admin?
end
结尾
这是我的会话控制器
module SessionsHelper
def sign_in(customer)
cookies.permanent.signed[:remember_token] = [customer.id, customer.salt]
self.current_customer = customer
end
def sign_out
cookies.delete(:remember_token)
self.current_customer = nil
end
def signed_in?
!current_customer.nil?
end
def current_customer?(customer)
return false unless current_customer
current_customer.id == customer.id
end
def current_customer=(customer)
@current_customer = customer
end
def current_customer
@current_customer ||= customer_from_remember_token
end
def authenticate
deny_access unless signed_in?
end
def deny_access
store_location
redirect_to signin_path, :notice => "Please sign in to access this page."
end
def redirect_back_or(default)
redirect_to(session[:return_to] || default)
clear_return_to
end
private
def customer_from_remember_token
Customer.authenticate_with_salt(*remember_token)
end
def remember_token
cookies.signed[:remember_token] || [nil, nil]
end
def store_location
session[:return_to] = request.fullpath
end
def clear_return_to
session[:return_to] = nil
end
end
这里是帮助文件
module SessionsHelper
def sign_in(customer)
cookies.permanent[:remember_token] = customer.remember_token
self.current_customer = customer
end
def signed_in?
!current_customer.nil?
end
def sign_out
self.current_customer = nil
cookies.delete(:remember_token)
end
def current_customer=(customer)
@current_customer = customer
end
def current_customer
@current_customer ||= Customer.find_by_remember_token(cookies[:remember_token])
end
def current_customer?(customer)
customer == current_customer
end
def redirect_back_or(default)
redirect_to(session[:return_to] || default)
session.delete(:return_to)
end
def store_location
session[:return_to] = request.fullpath
end
end
我正在关注http://ruby.railstutorial.org/chapters/上的教程，并且在第 10 章。但我也尝试通过 railcast 实现一个记住我的复选标记框，这似乎根本不起作用。（不同的代码）
再次感谢
我添加了这个以获得额外的支持
class ApplicationController < ActionController::Base
protect_from_forgery
before_filter :pages
def pages
@pages = Page.all
end
private
def current_customer
@current_customer ||= Customer.find(session[:customer_id]) if session[:customer_id]
end
helper_method :current_customer
def authorize
redirect_to login_url, alert: "Not authorized" if current_customer.nil?
end
include SessionsHelper
end
更新:: 在过滤之前尝试注释掉这里发生了什么。按照您的教程，我尝试使用您的方法来实现，以确保它不是一个小点或某种东西。但这就是我现在的新错误！
NameError in SessionsController#create

我不明白为什么这些方法没有定义。他们是自指的！！
