<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-&gt;validate([ 'title' =&gt; ['required'], 'release_date' =&gt; ['required', 'integer'], 'author' =&gt; ['required'], 'studio' =&gt; ['required'], 'description' =&gt; ['required'], ]); $request-&gt;release_date = (int)$request-&gt;release_date; $animeInfo = Anime::where('title', $request-&gt;oldTitle)-&gt;with('authors', 'studios')-&gt;first(); $author = Author::firstOrCreate(['author' =&gt; $request-&gt;author]); AuthorAnime::where([ ['author', $animeInfo-&gt;authors[0]-&gt;author], ['anime', $request-&gt;oldTitle] ])-&gt;update([ 'author' =&gt; $author-&gt;author, 'anime' =&gt; str_replace(' ', '-', $request-&gt;title) ]); $studio = Studio::firstOrCreate(['studio_name' =&gt; $request-&gt;studio]); StudioAnime::where([ ['studio', $animeInfo-&gt;studios[0]-&gt;studio_name], ['anime', $request-&gt;oldTitle] ])-&gt;update([ 'studio' =&gt; $studio-&gt;studio_name, 'anime' =&gt; str_replace(' ', '-', $request-&gt;title) ]); foreach ($request-&gt;all() as $key =&gt; $value) { if (property_exists($animeInfo, $key)) { if ($request-&gt;$key != $animeInfo-&gt;$key) { $updatedFields[$key] = $request-&gt;$key; } } } $animeInfo-&gt;update($updatedFields); return response()-&gt;json(['message' =&gt; 'Data was updated successfully. n Updated data: ' . implode(', ', array_keys($updatedFields))]); }</pre> <p>控制器代码:</p> <pre class="brush:php;toolbar:false;">$anime = new Anime(); return $anime-&gt;updateAnime($request);</pre> <p>问题是，它更新相关的表StudioAnime和AuthorAnime，它也在表Studio和动漫中创建新的数据，但它不更新表动漫。兄弟们，为啥这样，该怎么解决<br /><br />当在我以前的代码我只是更新数据没有检查它的变化都工作</p><p><br /></p> <pre class="brush:php;toolbar:false;">$animeInfo-&gt;update([ 'title' =&gt; str_replace(' ', '-',$request-&gt;title), 'poster' =&gt; $animeInfo-&gt;poster, 'description' =&gt; $request-&gt;description, 'release_date' =&gt; $request-&gt;release_date, 'trailer' =&gt; $animeInfo-&gt;trailer, ]); return response()-&gt;json(['message' =&gt; 'Data was updated successuflly']);```</pre> <p><br /></p>
