Falsche Datenaktualisierung im Laravel-Datenbankbetrieb

Question

以下是我模型中的函数代码:

public function updateAnime(Request $request)
{
    $updatedFields = [];

    $request->validate([
        'title' => ['erforderlich'],
        'release_date' => ['erforderlich', 'Ganzzahl'],
        'Autor' => ['erforderlich'],
        'studio' => ['erforderlich'],
        'Beschreibung' => ['erforderlich'],
    ]);

    $request->release_date = (int)$request->release_date;
    $animeInfo = Anime::where('title', $request->oldTitle)->with('authors', 'studios')->first();

    $author = Author::firstOrCreate(['author' => $request->author]);
    AutorAnime::where([
        ['Autor', $animeInfo->authors[0]->author],
        ['anime', $request->oldTitle]
    ])->update([
        'Autor' => $author->author,
        'anime' => str_replace(' ', '-', $request->title)
    ]);

    $studio = Studio::firstOrCreate(['studio_name' => $request->studio]);
    StudioAnime::where([
        ['studio', $animeInfo->studios[0]->studio_name],
        ['anime', $request->oldTitle]
    ])->update([
        'studio' => $studio->studio_name,
        'anime' => str_replace(' ', '-', $request->title)
    ]);

    foreach ($request->all() as $key => $value) {
        if (property_exists($animeInfo, $key)) {
            if ($request->$key != $animeInfo->$key) {
                $updatedFields[$key] = $request->$key;
            }
        }
    }

    $animeInfo->update($updatedFields);
    return Response()->json(['message' => 'Daten wurden erfolgreich aktualisiert. n Aktualisierte Daten: ' . implode(', ', array_keys($updatedFields))]);
}

控制器代码:

$anime = new Anime();
        return $anime->updateAnime($request);

Leute, warum passiert das und wie kann man es lösen? />

$animeInfo->update([
            'title' => str_replace(' ', '-',$request->title),
            'poster' => $animeInfo->poster,
            'description' => $request->description,
            'release_date' => $request->release_date,
            'trailer' => $animeInfo->trailer,
        ]);
        return Response()->json(['message' => 'Daten wurden erfolgreich aktualisiert']);```

不能用property_exist()函数获取列名，因为这些属性不能作为Model对象中的属性直接访问。

要检查这个，试试在tinker:

dd(User::first())

我的建议是，用attributesarray()或getAttributes()方法与array_keys()结合，获得模型的属性名称数组，这不就搞定了吗:

$animeAttributes = array_keys($animeInfo->getAttributes());

foreach ($request->all() as $key => $value) {

    if (in_array($key, $animeAttributes)) {

    /* ... */
