我认为只需要帮助就可以了。我一直在苦苦挣扎一段时间。这是我的第一篇文章，对不起，如果它不容易阅读。

Answer 1

correct_user？没有在任何地方定义。

redirect_to(root_url) unless correct_user?(@user)

Rails的语法糖将寻找模型标志correct_user或布尔返回函数#correct_user？吸气。我假设您正在尝试验证来自用户的更新请求实际上属于正确的用户。为此，您必须将current_user存储在会话中，然后检查请求参数[：id] == current_user.id

错误

Users_controller.rb

User_controller_test

users.yml里

users_edit_test

correct_user？没有在任何地方定义。
