I have the following in my root route:
我的基本路线如下:
$user = User::all();
return $user->column-one;
Which returns the exception Use of undefined constant one - assumed 'one' even though I do have a column called column-one from my users table. So how do I get column-one from my model?
它返回未定义常量1的异常使用——假设为“1”，尽管我确实有一个列，名为columone，来自我的users表。那么如何从模型中得到第一列呢?

After digging through the source code for the eloquent model I found the magic method __get and learned that it was just a wrapper for the public function getAttribute which takes a string thus I'm now able to retrieve the column via $user->getAttribute('column-one');.
在深入研究了有说服力的模型的源代码之后，我发现了神奇的方法__get，并了解到它只是一个公共函数getAttribute的包装器，它接受一个字符串，因此我现在可以通过$user->getAttribute('column- 1 ')检索列;

I haven't tried this, but am curious if using camelCase for it would work. That's how it works for things like routes. For example: $user->columnOne.
我还没有尝试过这个，但是我很好奇使用camelCase是否有用。这就是它的工作原理。例如:用户- > columnOne美元。
I would however recommend renaming that column. That really doesn't map well in a PHP app.
但是，我建议重新命名该专栏。这在PHP应用中并不是很好。
Update - Try this:
更新——试试这个:
$user->{"column-one"}
$ user - > { "列1 " }
