我做了两个迁移表用户角色和用户。当我迁移它。它说成功完成他们两个，但只有用户表是在数据库中没有用户角色。虽然数据库已经创建了role_id作为外键，但没有用户角色表在数据库中。

迁移表

下面是我的迁移代码

用户角色

<?php namespace App\Database\Migrations;

use CodeIgniter\Database\Migration;

class UserRoles extends Migration
{
    public function up()
    {
        $this->forge->addField([
            'role_id' => [
                'type' => 'INT',
                'constraint' => 11,
                'unsigned' => true,
                'auto_increment' => true
            ],
            'role' => [
                'type' => 'VARCHAR',
                'constraint' => 255
            ],
            'role_description' => [
                'type' => 'TEXT',
                'null' => true
            ],
            'created_at' => [
                'type' => 'timestamp',
                'default' => 'current_timestamp'
            ],
            'created_by' => [
                'type' => 'int',
                'constraint' => 11,
                'null' => true
            ],
            'updated_at' => [
                'type' => 'timestamp',
                'null' => true
            ],
            'updated_by' => [
                'type' => 'int',
                'constraint' => 11,
                'null' => true
            ],
            'deleted_at' => [
                'type' => 'timestamp',
                'null' => true
            ],
        ]);
        $this->forge->addKey('role_id', true);
        $this->forge->createTable('user_roles');
    }

    //--------------------------------------------------------------------

    public function down()
    {
        $this->forge->dropTable('user_roles');
    }
}

用户迁移代码

<?php namespace App\Database\Migrations;

use CodeIgniter\Database\Migration;

class Users extends Migration
{
    public function up()
    {
        $this->db->disableForeignKeyChecks();
        $this->forge->addField([
            'user_id' => [
                'type' => 'INT',
                'constraint' => 11,
                'unsigned' => true,
                'auto_increment' => true
            ],
            'first_name' => [
                'type' => 'VARCHAR',
                'constraint' => 255
            ],
            'last_name' => [
                'type' => 'VARCHAR',
                'constraint' => 255
            ],
            'email' => [
                'type' => 'VARCHAR',
                'constraint' => 255
            ],
            'password' => [
                'type' => 'VARCHAR',
                'constraint' => 255
            ],
            'role_id' => [
                'type' => 'INT',
                'constraint' => 11,
                'unsigned' => true,
            ],
            'transaction_pin' => [
                'type' => 'VARCHAR',
                'constraint' => 255
            ],
            'created_by' => [
                'type' => 'int',
                'constraint' => 11,
                'null' => true
            ],
            'updated_at' => [
                'type' => 'timestamp',
                'null' => true
            ],
            'updated_by' => [
                'type' => 'int',
                'constraint' => 11,
                'null' => true
            ],
            'deleted_at' => [
                'type' => 'timestamp',
                'null' => true
            ],
        ]);
        $this->forge->addKey('user_id', true);
        $this->forge->addForeignKey('role_id', 'user_roles', 'role_id', 'cascade', 'null');
        $this->forge->createTable('users');
        $this->db->enableForeignKeyChecks();
    }

    //--------------------------------------------------------------------

    public function down()
    {
        $this->db->disableForeignKeyChecks();
        $this->forge->dropTable('user_id');
        $this->db->enableForeignKeyChecks();
    }
}

有人能帮我一下吗
