Answer 1

当你在下面一行返回的观点：

return view('stations.show')->withStation('$station'); 

您需要可以使用双引号或根本不使用引号。使用单引号，您实际上将值设置为字符串"$station"而不是您创建的对象。

Answer 2

请重新写return view('stations.show')->withStation('$station');像 return view('stations.show')->with(['station' => $station]);

Answer 3

你可以试试你的控制器的编辑线84这样的：

return $view->with(compact('station')); 

采用紧凑的是在大多数情况下更快，更清洁，因为你已经建立的变量。

Answer 4

更改方法public function create()到：

public function create() 
{ 
    $station = new Station; 
    return view('stations.create')->with(compact('station')); 
}
