我正在使用cakephp 3.5（今天运行更新）来创建我的第一个非教程Web应用程序。我正在尝试设置我的应用，以便我可以编辑我的用户帐户详细信息（用户名和密码）。 我不确定我做了什么，但在登录时我实际上无法访问我的edit.ctp（视图）。我不断收到“无法找到当前实体的表类”错误。
我的目标是让用户能够编辑他们的用户名（这是一个电子邮件地址），并在他们想要的时候更改他们的密码。
有人可以帮助我锻炼我出错的地方，以及为什么我一直得到“无法找到当前实体的表类”错误以及我可以做些什么来解决它。 我已经阅读了尽可能多的相关文章。我已经尝试了各种“isAuthorised”函数版本，并且我不断收到同样的错误，所以我确信这是我不知道该找什么的东西。
以下是我的代码：

答案 0 :(得分：6)
问题在于AppController beforeRender方法中你有这个..
$this -> set('user', $this -> Auth -> user());
这意味着您将与所有控制器和操作共享当前用户。
另请注意，在用户控制器的编辑操作中，您还调用了变量$user，并通过set将其发送到视图...
这就是问题的根源，这就是为什么如果你用users更改名称就行了！在$user方法中发送的beforeRender与用户控制器中的编辑操作中发送的$user之间似乎存在冲突
答案 1 :(得分：1)
好的，经过大量的反复试验后，我解决了这个问题。这是一个简单的修复，虽然我不知道它为什么会起作用...所以如果有人能解释那会很棒：我将控制器文件中的$user变量的编辑功能更改为{{1以及edit.ctp文件中的$users变量到$user，并且它已经工作了。
