假设您在contacts/{ slug }之类的路由中使用了子弹

public function show(contact $contact)
{
    dd(['contact' => $contact]);
    //return back()->with('success','Message Contents Are Already Shown');
}

接收一个id而不是一个联系人...您正在函数参数中初始化/声明为contact，这就是为什么它以某种方式被强制转换为联系人...但是它是一个id，您应该执行以下操作：

public function show($id)
{
    $contact = Contact::findOrFail($id);
    dd(['contact' => $contact]);
    //return back()->with('success','Message Contents Are Already Shown');
}

Laravel，Show（），Edit（），更新功能不起作用
