我正在做michael hartl的ruby on rails教程,当应用程序部署时,本地一切都很好,但在heroku上就不行了......这个问题在本书第7章之前就出现了:http://ruby.railstutorial.org/ruby-on-rails-tutorial-book#top
是否有任何细节你需要调试这个问题?请让我知道.....
下面是heroku日志:

我在做哈特教程的时候也遇到了同样的问题。我运行了heroku run db:migrate....我确保它是最新的git push heroku....我在数据库中为我的一个用户添加了remember_key。它在schema.rb文件中。
我终于找到了答案:
user.rb:
添加:记住令牌到attr_accessible
例如:“attr_accessible:名称,:电子邮件,:密码,:密码确认,:记住令牌”
由于某些原因,这是遗漏的教程,即使现在我知道什么是错的,这是有意义的。
希望这对你有帮助:)

动态查找器仅在您要搜索的属性存在时才起作用。可能是您没有运行所有迁移,也可能是您根本没有该属性(remember_token)或拼错了该属性。

我遇到了同样的问题,我不得不说,恕我直言,没有必要将
:remember_token
添加到attr_accessible
字段。这样做会暴露:remember_token
,创建getter和setter,这是不必要的,因为:remember_token
必须被视为内部变量。我解决了重新启动Heroku应用程序的问题,如下所示:heroku-nomethod-error-remember-token
重新启动后,应用程序正常工作,就像它在本地做的那样。
wj8zmpe14#
它失败了,因为它没有找到下面的
find_by_remember_token
方法的定义。我记得remember_token
是在Hartl教程的session_helper
中定义的。它似乎是在调用signed_in?
方法时出现的。能否粘贴
session_helper.rb
和User
型号代码?nxagd54h5#
试着运行
heroku restart
。它对我很有效。需要注意的是,根据r4m's answer,不建议将
:remembered_token
添加到attr_accessible
声明中(Hartl在本教程中没有这样做是有原因的)。fwzugrvs6#
行:
Rails不知道'find_by_remember_token'是什么,这意味着它要么不存在(也就是说,它是一个拼写错误),要么通常用于确定类属性的数据库不知道这个字段。
假设这不是打字错误,那么迁移数据库将是一个选项:

当我尝试推送到Heroku和Amazon时,我遇到了内部服务器错误。在将应用程序推送到服务器之前,我必须预编译我的资产。如果这是您的问题,最简单的解决方案是运行
或者添加load“deploy/assets”到capfile,如果您使用Capistrano的话。我被告知您可以将以下内容添加到您的deploy.rb文件中,但我无法让它工作。
7fhtutme8#
对我有效的方法是在User模型中定义create_remember_token方法,与教程中描述的完全相同。
然后在before_保存方法中调用它。
我以前没有把它作为方法声明。当它在我的计算机上工作时,它在Heroku中失败了。
而且,跑也无妨:
