我正在尝试在React中创建简单的upvote系统,但是我收到奇怪的错误消息,即使我在db中定义了投票,并且投票当前为0,投票还是为零。问题出在 class AddSlugToPosts extends Migration { public function up() { Schema::table('posts', function ($table) { $table->string('slug')->unique()->after('body')->default(); }); } public function down() { Schema::table('posts', function ($table) { $table->dropColumn('slug'); }); } } public function rules() { return [ 'title' => 'required|max:255', 'body' => 'required', 'slug' => 'required|alpha_dash|min:5|max:255|unique:posts,slug' ]; } public function store(PostRequest $request) { $post = Post::create($request->all()); Session::flash('success', 'The blog post was successfully saved!'); return redirect()->route('posts.show', $post->id); } 中功能,并且我得到正确的ID。

有人可以解释为什么我遇到此错误吗?
