Ruby on rails RubyonRails-会话

我将遵循本教程：

我的会话有问题。每次我登录到我的应用程序，我没有得到会话，但会被重定向到我的用户页面。创建/注册用户也很有效

会话\u helper.rb

module SessionsHelper

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

def signed_in?
    @current_user != nil
    #!@current_user.nil?
end

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

def current_user?(user)
    @current_user = user
end

def sign_out
    self.current_user = nil
    cookies.delete(:remember_token)
end



def store_location
    session[:return_to] = request.url
end
end

class SessionsController < ApplicationController

def new
    @title = "| Signin"
end

def create
    user = User.find_by_email(params[:session][:email].downcase)
    if user && user.authenticate(params[:session][:password])
        sign_in user
        redirect_to user
    else
        #Fehlermeldung anzeigen falls login nicht erfolgreich war
        flash.now[:error] = "Invalid email/password combination"
        render 'new'
    end
end

def destroy
    sign_out
    redirect_to root_url
end

end

会话\u控制器.rb

module SessionsHelper

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

def signed_in?
    @current_user != nil
    #!@current_user.nil?
end

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

def current_user?(user)
    @current_user = user
end

def sign_out
    self.current_user = nil
    cookies.delete(:remember_token)
end



def store_location
    session[:return_to] = request.url
end
end

class SessionsController < ApplicationController

def new
    @title = "| Signin"
end

def create
    user = User.find_by_email(params[:session][:email].downcase)
    if user && user.authenticate(params[:session][:password])
        sign_in user
        redirect_to user
    else
        #Fehlermeldung anzeigen falls login nicht erfolgreich war
        flash.now[:error] = "Invalid email/password combination"
        render 'new'
    end
end

def destroy
    sign_out
    redirect_to root_url
end

end

class sessioncontroller

我发现至少有一个错误：

def current_user?(user)
    @current_user = user
end

应该是

def current_user?(user)
    @current_user == user
end

=，而不是=，因为您应该检查当前用户是否与其他用户相等，而不是进行分配。

如果我忘记了一些文件，请询问我，我将添加这些文件。代码就是这样做的……它在用户中签名，然后重定向到用户页面。你希望它做什么？不，每次我提供我的帐户详细信息。。我来到我的个人主页。。但是当我点击登录按钮时。。。它指引我进入登录页面，尽管我已经登录了！您确定在浏览器中启用了Cookie吗？是的，我启用了@很抱歉，这不起作用：/
