我正在尝试重定向到单击登录的页面,但是登录后它不会重定向到上一页而是停留在登录页面上(尽管用户已经登录)。这是我的代码:
session_helper.rb
module SessionsHelper
def sign_in(user)
remember_token = User.new_remember_token
cookies.permanent[:remember_token] = remember_token
user.update_attribute(:remember_token, User.encrypt(remember_token))
self.current_user = user
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
session_controller.rb
class SessionsController < ApplicationController
include SessionsHelper
def new
end
def create
user = User.find_by_username(params[:session][:username])
if user && user.authenticate(params[:session][:password])
cookies.permanent[:remember_token] = user.remember_token
#redirect_to root_url,:notice => "Logged in!"
redirect_back_or user
else
flash[:error] = 'Invalid email/password combination' # Not quite right!
render 'new'
end
end
def destroy
cookies.delete(:remember_token)
#session[:user_id] = nil
redirect_to root_url, :notice => "Logged out!"
end
end
我还尝试在 sessions_controller.rb 中编写创建函数
redirect_to request.referer
但它不起作用。
我错过了什么吗?
谢谢你的帮助!
