<p>以下是我模型中的函数代码:</p> <pre class="brush:php;toolbar:false;">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($updatedFields))]); }</pre> <p>控制器代码:</p> <pre class="brush:php;toolbar:false;">$anime = new Anime(); return $anime->updateAnime($request);</pre> <p>Leute, warum passiert das und wie kann man es lösen? /></p> <pre class="brush:php;toolbar:false;">$animeInfo->update([ 'title' => str_replace(' ', '-',$request->title), 'poster' => $animeInfo->poster, 'description' => $request->description, 'release_date' => $request->release_date, 'trailer' => $animeInfo->trailer, ]); return Response()->json(['message' => 'Daten wurden erfolgreich aktualisiert']);```</pre> <p><br /></p>

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)) {
