Laravel 7 updateOrCreate 不起作用

Question

我在使用 updateOrCreate 函数时遇到了一个奇怪的问题。如果我的记录是新的，则没有问题。但是如果记录存在，它就永远不会更新。比如我打了这个电话，好像更新了。

刀片

<form action="{{ route('updateOrCreate') }}" method="post">
    @csrf
    <div class="ms-4">
        <div class="form-check">
            <input class="form-check-input" type="radio" value="1" id="yes" name="question" {{ optional(auth()->user()->skillMaster)->question == 1 ? 'checked' : '' }}>
            <label class="form-check-label" for="yes">
                Yes
            </label>
        </div>
        <div class="form-check">
            <input class="form-check-input" type="radio" value="0" id="no" name="question" {{ optional(auth()->user()->skillMaster)->question == 0 ? 'checked' : '' }}>
            <label class="form-check-label" for="no">
                No
            </label>
