解决方法

所以我也在做Hart教程并且正在进入相同的问题.我运行了heroku运行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一个remember_key.它位于schema.rb文件中.

我终于找到了答案：

user.rb：

add：remember_token to attr_accessible

例如：“attr_accessible：name,：email,：password,：password_confirmation,：remember_token”

出于某种原因,这是在教程之外,即使现在我知道什么是错的,这是有道理的.添加这个后我重新推到了heroku和Viola ….

希望这可以帮助：)
