Database Migration File

<?php

use Phinx\Migration\AbstractMigration;

class CreateRuleTable extends AbstractMigration
{
    /**
     * Change Method.
     *
     * Write your reversible migrations using this method.
     *
     * More information on writing migrations is available here:
     * http://docs.phinx.org/en/latest/migrations.html#the-abstractmigration-class
     *
     * The following commands can be used in this method and Phinx will
     * automatically reverse them when rolling back:
     *
     *    createTable
     *    renameTable
     *    addColumn
     *    addCustomColumn
     *    renameColumn
     *    addIndex
     *    addForeignKey
     *
     * Any other destructive changes will result in an error when trying to
     * rollback the migration.
     *
     * Remember to call "create()" or "update()" and NOT "save()" when working
     * with the Table class.

        $table = $this->table('rule', ['id' => false, 'primary_key' => ['id'], 'engine' => 'InnoDB', 'collation' => 'utf8mb4_general_ci', 'comment' => 'Rule table']);

        // Add data fields
        $table->addColumn('id', 'integer', ['identity' => true, 'signed' => false, 'limit' => 11, 'comment' => 'Primary key ID'])

            ->addColumn('v1', 'string', ['default' => '', 'limit' => 128])
            ->addColumn('v2', 'string', ['default' => '', 'limit' => 128])
            ->addColumn('v3', 'string', ['default' => '', 'limit' => 128])
            ->addColumn('v4', 'string', ['default' => '', 'limit' => 128])

Casbin Configuration

For permission rule model configuration syntax, please refer to: https://casbin.org/docs/zh-CN/syntax-for-models

<?php

return [
    'default' => [
        'model' => [
            'config_type' => 'file',
            'config_file_path' => config_path() . '/casbin-restful-model.conf', // Permission rule model configuration file
            'config_text' => '',
        ],
        'adapter' => [
            'type' => 'model', // model or adapter
            'class' => \app\model\Rule::class,
        ],
    ],
    // Multiple permission models can be configured
    'rbac' => [
        'model' => [
            'config_type' => 'file',
            'config_file_path' => config_path() . '/casbin-rbac-model.conf', // Permission rule model configuration file
            'config_text' => '',
        ],
        'adapter' => [
            'type' => 'model', // model or adapter
            'class' => \app\model\RBACRule::class,
        ],
    ],
];

Adapter

The current composer package adapts to the model method of think-orm. For other ORMs, please refer to vendor/teamones/src/adapters/DatabaseAdapter.php.

Then modify the configuration.

return [
    'default' => [
        'model' => [
            'config_type' => 'file',
            'config_file_path' => config_path() . '/casbin-restful-model.conf', // Permission rule model configuration file
            'config_text' => '',
        ],
        'adapter' => [
            'type' => 'adapter', // Set the type to adapter mode
            'class' => \app\adapter\DatabaseAdapter::class,
        ],
    ],
];
