无法简单登录 - 我不知道如何纠正它。来回遍布指南，似乎无法找到导致此错误的错误

Answer 1

在线教程在sessions_helper.rb中有以下定义

  def sign_in(user)
    cookies.permanent.signed[:remember_token] = [user.id, user.salt]
    self.current_user = user
  end
.
.
.
  def sign_out
    cookies.delete(:remember_token)
    self.current_user = nil
  end

我将它们更改为以下内容，并且能够无错误地登录/注销。

  def sign_in(user)
    cookies.permanent.signed[:remember_token] = [user.id, user.salt]
    @current_user = user
  end
.
.
.
  def sign_out
    cookies.delete(:remember_token)
    @current_user = nil
  end

此外，要确认您已登录，请将URL localhost：3000 / users /（您的用户ID）更改为另一个用户ID。它会显示用户信息。点击顶部的个人资料链接，它会返回到您的个人资料。设置应用程序，以便此链接将到达登录用户的配置文件。
