如何使用迁移重命名 laravel 中的列?
我有如下所述的专栏:
public function up()
{
Schema::create('stnk', function(Blueprint $table)
{
$table->increments('id');
$table->string('no_reg', 50)->unique();
$table->string('no_bpkb', 50)->unique();
$table->string('nama_pemilik', 100);
$table->string('alamat');
$table->string('merk', 50);
$table->string('tipe', 50);
$table->string('jenis', 50);
$table->smallInteger('tahun_pembuatan');
$table->smallInteger('tahun_registrasi');
$table->smallInteger('isi_silinder');
$table->string('no_rangka', 50);
$table->string('no_mesin', 50);
$table->string('warna', 50);
$table->string('bahan_bakar', 50);
$table->string('warna_tnkb', 50);
$table->string('kode_lokasi', 50);
$table->date('berlaku_sampai');
$table->timestamps();
$table->index('created_at');
$table->index('updated_at');
});
}
我已经制作了播种机到stnk表
现在我想重命名为.
我在“作曲家”中添加了一个“学说/dbal”,并做了一个.id
id_stnk
composer update
我已经进行了迁移。
然后我添加了新方法rename_column:php artisan migration:make rename_column
Schema::table('stnk', function(Blueprint $table)
{
$table->renameColumn('id', 'id_stnk');
});
然后我试图运行命令,但我得到了错误,如下面提到的:php artisan migrate
[Ulluminate\Database\QueryException]
