Ruby on Rails登录后重定向

Question

我正在关注http://ruby.railstutorial.org上的教程

当用户访问受限页面时提示输入登录信息，然后登录后重定向回受限页面时，我已经设法做到了。

但是，登录后，我已经注销并与另一个用户登录，我将被重定向回该页面，而不是重定向到默认会话的默认主页。

我的会话控制器

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_back_or user
  # Sign the user in and redirect to the user's show page.
else
  # Create an error message and re-render the signin form.
  flash.now[:error] = 'Invalid email/password combination'
    render 'new'
end
end
....
end

我的会话助手

module SessionsHelper
....
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

Answer 1

添加session.delete(:return_to)创建方法

def create
  user = User.find_by_email(params[:session][:email])
  if user && user.authenticate(params[:session][:password])
    sign_in user
    session.delete(:return_to)
    redirect_back_or user
    # Sign the user in and redirect to the user's show page.
  else
    # Create an error message and re-render the signin form.
    flash.now[:error] = 'Invalid email/password combination'
    render 'new'
  end
end
