“从空值创建默认对象”

Question

我正在尝试向数据库中插入数据，但收到错误"Creating default object from empty value" 仍然不明白，这个错误是从哪里来的？

在我的控制器中

public function store(Request $request)
    {
        $request->validate([
            'amount' => 'required',
            'method' => 'required',
        ]);
        $payrolls = new Payroll();
        $payrolls->employee_id = auth()->user()->id;
        $payrolls->account_id = auth()->user()->id;
        $payrolls->employee_name = $request->get('employee_name');
        $payrolls->description = $request->get('description');
        $payrolls->account = $request->get('account');
        $payrolls->amount = $request->get('amount');
        $payrolls->method = $request->get('method');
        $payrolls->save();
        return response()->json(['created' => true]);
    }

有什么帮助吗？谢谢......

正如@arm 所说，您的代码中有错字，这会导致您遇到错误。
下面的代码应该使它工作。
我还建议您使用 $request->input('****'); 而不是像您正在使用的动态变量 $request->account;

public function store(Request $request)
{
    $request->validate([
        'amount' => 'required',
        'method' => 'required',
    ]);

    $payrolls = new Payroll();
    $payrolls->employee_id = auth()->user()->id;
    $payrolls->account_id = auth()->user()->id;
    $payrolls->employee_name = $request->input('employee_name');
    $payrolls->description = $request->input('description');
    $payrolls->account = $request->input('account');
    $payrolls->amount = $request->input('amount');
    $payrolls->method = $request->input('method');
    $payrolls->save();

    return response()->json(['created' => true]);
}

您还可以查看Payroll::create()，它可以更轻松地在数据库中创建条目，而不是创建new Payroll()，并在最后保存。 https://laravel.com/docs/5.7/eloquent#mass-assignment
