Installation

Add the package to your composer.json:

{
    "require": {
        "carono/yii2-url-behavior": "*"
    }
}

Usage

Attaching the Behavior

Attach the behavior to your ActiveRecord model:

use carono\yii2\behaviors\UrlBehavior;

class Post extends \yii\db\ActiveRecord
{
    public function behaviors()
    {
        return [
            [
                'class' => UrlBehavior::class,
                'rules' => [
                    ['view', 'url' => ['post/view', 'id' => 'id']],
                    ['update', 'url' => ['post/update', 'id' => 'id'], 'role' => 'admin'],
                    ['delete', 'url' => ['post/delete', 'id' => 'id'], 'role' => ['admin', 'moderator']],
                ],
                'defaultUrl' => ['site/index'],
                'functionAlias' => 'getUrl' // Default method name
            ]
        ];
    }
}

Configuration Options

• rules: Array of URL rules or a string method name that returns rules
• defaultUrl: Default URL when no rules match
• functionAlias: Method name to expose (default: getUrl)
• authManager: Auth manager component ID (default: authManager)
• ruleClass: Custom rule class implementation

Rule Configuration

Each rule can have these properties:

• action: Action name (required)
• url: URL pattern or callable (required)
• role: Role or array of roles (optional)
• application: Application ID restriction (optional)
• params: Additional parameters (optional)

URL Generation

$post = Post::findOne(1);

// Get URL as array
$urlArray = $post->getUrl('view');

// Get absolute URL string
$urlString = $post->getUrl('view', true);

Advanced Rule Examples

'rules' => [
    [
        'view', 
        'url' => ['post/view', 'id' => 'id'],
        'role' => 'user',
        'application' => 'frontend'
    ],
    [
        'update',
        'url' => function($model) {
            return ['post/update', 'id' => $model->id, 'slug' => $model->slug];
        },
        'role' => ['admin', 'editor']
    ],
    [
        'delete',
        'url' => ['post/delete'],
        'params' => [
            'id' => 'id',
            'timestamp' => function($model) {
                return time();
            }
        ]
    ]
]

Rule Class Reference

The UrlRule class provides these properties:

• action: Target action name
• url: URL pattern or callable
• role: Role(s) required
• application: Application restriction
• params: Parameter configuration
• authManager: Auth manager component
• cache: Cache component for role caching
• model: Related model instance

Caching

The behavior supports role caching to improve performance:

'rules' => [
    ['view', 'url' => ['post/view'], 'role' => 'user', 'duration' => 3600]
]

Advanced Usage

Custom Rule Class

Create custom rule class by extending UrlRule:

class CustomUrlRule extends UrlRule
{
    public function compare($action, $user)
    {
        // Custom logic here
        return parent::compare($action, $user);
    }
}

Dynamic Rules

Define rules using a model method:

public function behaviors()
{
    return [
        [
            'class' => UrlBehavior::class,
            'rules' => 'getUrlRules'
        ]
    ];
}

public function getUrlRules()
{
    return [
        ['view', 'url' => ['post/view', 'id' => 'id']],
        // ... more rules
    ];
}
