codeigniter 4 migration file not creating table - codeigniter

Question

when I first made a migration file for table users, the public function down() in the migration file was empty. when I run php spark migrate the table users was created.
then I generated another migration file with php spark make:migration users, made a few adjustments according to the new table structure and put $this->forge->dropTable('users'); in the public function down(). but when I run php spark migrate again, the users table doesn't have the new field..
I'm using codeigniter 4 and mysql. here's my code
UserModelphp
<?php
namespace App\Models;
use CodeIgniter\Model;
class UserModel extends Model
{
protected $DBGroup = 'default';
protected $table = 'users';
protected $primaryKey = 'id';
protected $useAutoIncrement = true;
protected $insertID = 0;
protected $returnType = 'array';
protected $useSoftDeletes = false;
protected $protectFields = true;
// added created_at and updated_at
protected $allowedFields = ['username', 'password', 'foto', 'nama', 'email', 'telepon', 'created_at', 'updated_at'];
// Dates
protected $useTimestamps = false;
protected $dateFormat = 'datetime';
protected $createdField = 'created_at';
protected $updatedField = 'updated_at';
protected $deletedField = 'deleted_at';
// Validation
protected $validationRules = [];
protected $validationMessages = [];
protected $skipValidation = false;
protected $cleanValidationRules = true;
// Callbacks
protected $allowCallbacks = true;
protected $beforeInsert = [];
protected $afterInsert = [];
protected $beforeUpdate = [];
protected $afterUpdate = [];
protected $beforeFind = [];
protected $afterFind = [];
protected $beforeDelete = [];
protected $afterDelete = [];
}
first migration file
<?php
namespace App\Database\Migrations;
use CodeIgniter\Database\Migration;
class Users extends Migration
{
public function up()
{
// tabel users
$this->forge->addField([
'id' => [
'type' => 'INT',
'constraint' => 7,
'auto_increment' => true,
],
'username' => [
'type' => 'VARCHAR',
'constraint' => 50,
'null' => false,
],
'password' => [
'type' => 'VARCHAR',
'constraint' => 255,
'null' => false,
],
'profile_pic' => [
'type' => 'VARCHAR',
'constraint' => 50,

'nama' => [
'type' => 'VARCHAR',
'constraint' => 50,

'email' => [
'type' => 'VARCHAR',
'constraint' => 100,
],
'telepon' => [
'type' => 'VARCHAR',
'constraint' => 10,
],
]);
$this->forge->addKey('id', true);
$this->forge->createTable('users');
}
public function down()
{
// hapus tabel users
}
}
new migration file
<?php
namespace App\Database\Migrations;
use CodeIgniter\Database\Migration;
class Users extends Migration
{
public function up()
{
// tabel users
$this->forge->addField([
'id' => [
'type' => 'INT',
'constraint' => 7,
'auto_increment' => true,
],
'username' => [
'type' => 'VARCHAR',
'constraint' => 50,
'null' => false,
],
'password' => [
'type' => 'VARCHAR',
'constraint' => 255,
'null' => false,
],
'foto' => [
'type' => 'VARCHAR',
'constraint' => 50,
],
'nama' => [
'type' => 'VARCHAR',
'constraint' => 50,
],
'email' => [
'type' => 'VARCHAR',
'constraint' => 100,
],
'telepon' => [
'type' => 'VARCHAR',
'constraint' => 10,
],
'created_at DATETIME DEFAULT CURRENT_TIMESTAMP',
'updated_at DATETIME DEFAULT CURRENT_TIMESTAMP',
]);
$this->forge->addKey('id', true);
$this->forge->createTable('users');
}
public function down()
{
// hapus tabel users
$this->forge->dropTable('users');
}
}
can someone tell me what I'm doing wrong? any help is appreciated

Answer 1

Explanation:
The down() method isn't called when you execute php spark migrate.
The down() method is run when you perform a migration rollback process using php spark migrate:rollback.
Solution:
Add the $this->forge->dropTable('users'); line of code at the beginning of the up() method of the "new migration file".
new migration file
// ...
class Users extends Migration
{
public function up()
{
$this->forge->dropTable('users');
// ...
}
// ....
}
The purpose of the down() method is to "reverse" everything performed in the up() method.
Extra Notes:
Considering that in your new migration, you're only renaming an existing table column (profile_pic -> foto) and adding timestamp columns, it would make more sense if you specified a more meaningful "migration name".
In addition, instead of dropping & recreating the existing table, modify the table instead.
I.e:
new migration file
A. Command (Create the new migration):
php spark make:migration alter_users_rename_profile_pic_add_timestamps
B. Generated migration.
<?php
namespace App\Database\Migrations;
use CodeIgniter\Database\Migration;
class AlterUsersRenameProfilePicAddTimestamps extends Migration
{
private $tableName = "users";
public function up()
{
$this->forge->modifyColumn($this->tableName, [
"profile_pic" => [
'name' => 'foto',
'type' => 'VARCHAR',
'constraint' => 50,
]
]);
$this->forge->addColumn($this->tableName, [
'created_at DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP',
'updated_at DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP',
]);
}
public function down()
{
$this->forge->modifyColumn($this->tableName, [
"foto" => [
'name' => 'profile_pic',
'type' => 'VARCHAR',
'constraint' => 50,
]
]);
$this->forge->dropColumn($this->tableName, ["created_at", "updated_at"]);
}
}
