外部キー制約に短い名前をつける
$table->foreign('team_youtube_id', 'tedh_idfk_1') ->references('id') ->on('team_youtubes') ->onDelete('cascade');
これでいうと、「tedh_idfk_1」がそれにあたります。
具体例
<?php use Illuminate\Support\Facades\Schema; use Illuminate\Database\Schema\Blueprint; use Illuminate\Database\Migrations\Migration; class CreateTeamYoutubeDownloadHistories extends Migration { /** * Run the migrations. * * @return void */ const TABLE_NAME = "team_youtube_download_histories"; public function up() { if (Schema::hasTable(self::TABLE_NAME)) { return; } Schema::create(self::TABLE_NAME, function (Blueprint $table) { $table->bigIncrements('id'); $table->bigInteger('team_youtube_id')->unsigned(); $table->timestamps(); $table->foreign('team_youtube_id', 'tedh_idfk_1') ->references('id') ->on('team_youtubes') ->onDelete('cascade'); }); } /** * Reverse the migrations. * * @return void */ public function down() { Schema::drop(self::TABLE_NAME); } }
