Question

我创建了一个迁移：

public function up()
{
    Schema::create('accounts', function(Blueprint $table) {
        $table->increments('id')->primary()->nullable(false)->index();
        $table->string('username', 32)->nullable(false)->index();
        $table->string('sha_pass_hash', 40)->nullable(false);
        $table->string('sessionkey', 80)->nullable(false);
        $table->string('v', 64)->nullable(false);
        $table->string('s', 64)->nullable(false);
        $table->string('token_key', 100)->nullable(false);
        $table->string('email', 255)->nullable(false)->unique();
        $table->timestamp('joindate')->nullable(false)->useCurrent();
        $table->string('last_ip', 15)->nullable(false)->default('127.0.0.1');
        $table->string('last_attempt_ip', 15)->nullable(false)->default('127.0.0.1');
        $table->unsignedInteger('failed_logins', 10)->nullable(false)->default(0);
        $table->unsignedTinyInteger('locked', 3)->nullable(false)->default(0);
        $table->timestamp('last_login')->nullable(false)->default('0000-00-00 00:00:00');
        $table->tinyInteger('online', 3)->nullable(false)->default(0);
        $table->unsignedTinyInteger('expansion', 3)->nullable(false)->default(6);
        $table->bigInteger('mutetime', 20)->nullable(false);
        $table->string('mutereason', 255)->nullable(false);
        $table->string('muteby', 50)->nullable(false);
        $table->unsignedTinyInteger('locale', 50)->nullable(false);
        $table->string('os', 3)->nullable(false);
        $table->unsignedInteger('recruiter', 10)->nullable(false);
        $table->unsignedInteger('battlenet_account', 10)->nullable(true)->default(NULL);
        $table->tinyInteger('battlenet_index', 3)->nullable(true)->default(NULL);
    });
}

当我试图执行命令时

php artisan migrate

我收到错误：

我注意到每个整数类型在sql查询中获得auto_increment primary key。我认为这可能是问题，因为我们知道自动增量列不能有默认值。

如果您查看unsignedInteger方法的source code，您会注意到第二个参数没有指定长度，而是指定autoIncrement布尔值。您需要相应地更新各种整数方法。
