模式构建器laravel迁移在两列中是唯一的
如何在两列上设置唯一约束? class MyModel extends Migration { public function up() { Schema::create('storage_trackers', function(Blueprint $table) { $table->increments('id'); $table->string('mytext'); $table->unsignedInteger('user_id'); $table->engine = 'InnoDB'; $table->unique('mytext', 'user_id'); }); } } MyMode::create(array('mytext' => 'test', 'user_id' => 1); // this fails?? MyMode::create(array('mytext' => 'test', 'user_id' => 2);
