我正在使用 Laravel 进行项目,并且在删除自定义 morphPivot 关系时遇到一些问题。当我尝试删除关系时,出现以下错误:Illuminate/Database/QueryException with message 'SQLSTATE[42S22]: Column not found: 1054 Unknown column '' in 'where clause' (SQL: delete from `comment` where (`` = 01418755-c68e-4ea5-8043-cef348c47445))'从它我认为 laravel 正在尝试通过 ids 删除,但 id 列没有名称,所以它找不到它。但是,我认为我明确定义了 id 列。这是我的类实现:<?phpuse Illuminate\Support\Facades\Schema;use Illuminate\Database\Schema\Blueprint;use Illuminate\Database\Migrations\Migration;class CreateCommentTable extends Migration{ /** * Run the migrations. * * @return void */ public function up() { Schema::create('comment', function (Blueprint $table) { $table->uuid('id'); $table->primary('id'); $table->text('content'); $table->boolean('spoiler')->default(false); $table->boolean('hidden')->default(false); $table->boolean('edited')->default(false); $table->uuid('parent_id')->nullable(); $table->uuid('user_id'); $table->uuid('commentable_id'); $table->string('commentable_type'); $table->json('meta')->nullable(); $table->timestamps(); }); } /** * Reverse the migrations. * * @return void */ public function down() { Schema::dropIfExists('comment'); }}
