README

This migration allows one to define the desired 'state' of rbac item structure.

A multidimensional array is used to define how the desired item structure should look after the migration.

Following the style of puppet config, the main attribute defining the desired or expected state of an item is the ensure parameter.

Since this type of migration change security related data, it is recommended to rather define a defensive configuration.

Installation

composer require dmstr/yii2-rbac-migration

Example usage

<?php

use dmstr\rbacMigration\Migration;
use yii\rbac\Item;

class m000000_000000_my_example_migration extends Migration {

    // define default params for al items
    public $defaultFlags = [
        'ensure' => self::PRESENT,
        'replace' => false,
    ];

    public $privileges = [
        [
            'name' => 'Role1',
            'type' => Item::TYPE_ROLE,
            'description' => 'My custom description',
            'ensure' => self::PRESENT,
            'replace' => true,
            'children' => [
                [
                    'name' => 'permission1',
                    'type' => Item::TYPE_PERMISSION,
                    'rule' => [
                       'name' => 'Rule0',
                       'class' => some\namespaced\Rule::class
                   ]
                ],
                [
                    'name' => 'permission2',
                    'type' => Item::TYPE_PERMISSION,
                    'ensure' => self::MUST_EXIST
                ],
                [
                    'name' => 'Role1',
                    'ensure' => self::PRESENT,
                    'children' => [
                        [
                            'name' => 'permission3',
                            'type' => Item::TYPE_PERMISSION
                        ]
                    ]
                ]
            ]
        ],
        [
            'name' => 'permission3',
            'type' => Item::TYPE_PERMISSION,
            'ensure' => self::ABSENT
        ],
    ];
}

config params per privilege item

• default params for all items are defined via protected $_defaultFlagsStruct array
• default params can be defined/overridden per migration instance via public $defaultFlags
• params which are set directly at the items have the highest priority

defined params are merged per item.

valid flags for ensure param

hints for self::ABSENT

• If defined as item param, the item will be removed regardless of its position.
• So if you define ensure => self::ABSENT in child items, NOT only the child relation but the item will be removed!
• if auth items are defined in DB and the auth tables has FK with cascade, child relations for this item may be deleted by the db.

hints for rules

• if defined rules are assigned to item "by name".
• if not exists it will be created with the given class property.
• if rule with given name already exists and replace is set to true, rule will be updated, otherwise existing rule will be used.

deprecated item params

the params _exists and _force are deprecated but still valid and will be replaced with new params scheme

shortcut syntax for mass assignments

to be able to quickly define mass assignments a special shortcut syntax where item is just a string can be used. The string will be set as item['name'] property, all other params are used from (defined) defaults.

Example:

    public $defaultFlags = [
        'type'    => Item::TYPE_PERMISSION,
        'ensure'  => self::MUST_EXIST,
        'replace' => false,
    ];
    public $privileges = [
            [
            'name'        => 'PublicationEditor',
            'type'        => Item::TYPE_ROLE,
            'ensure'      => self::PRESENT,
            'replace'     => true,
            'description' => 'Create, edit, delete publication items.',
            'children'    => [
                'publication_default',
                'publication_crud_index',
                'publication_crud_publication-item_create',
                'publication_crud_publication-item_delete',
                'publication_crud_publication-item_index',
                'publication_crud_publication-item_update',
                'publication_crud_publication-item_view',
            ]
        ]
    ];
