+# Using Dependency Injection With Active Record
+
+Using [dependency injection](https://github.com/yiisoft/di) in the Active Record model allows to inject dependencies 
+into the model and use them in the model methods.
+
+To create an Active Record model with dependency injection, you need to use 
+a [factory](https://github.com/yiisoft/factory) that will create an instance of the model and inject the dependencies 
+into it.
+
+## Define The Active Record Model
+
+Yii Active Record provides a `FactoryTrait` trait that allows to use the factory with the Active Record class.
+
+```php
+use Yiisoft\ActiveRecord\ActiveQueryInterface;
+use Yiisoft\ActiveRecord\ActiveRecord;
+use Yiisoft\ActiveRecord\Trait\FactoryTrait;
+
+#[\AllowDynamicProperties]
+final class User extends ActiveRecord
+{
+    use FactoryTrait;
+
+    public function __construct(private MyService $myService)
+    {
+    }
+
+    public function getTableName(): string
+    {
+        return '{{%user}}';
+    }
+
+    public function relationQuery(string $name): ActiveQueryInterface
+    {
+        return match ($name) {
+            'profile' => $this->hasOne(Profile::class, ['id' => 'profile_id']),
+            'orders' => $this->hasMany(Order::class, ['user_id' => 'id']),
+            default => parent::relationQuery($name),
+        };
+    }
+
+    public function getProfile(): Profile|null
+    {
+        return $this->relation('profile');
+    }
+
+    /** @return Order[] */
+    public function getOrders(): array
+    {
+        return $this->relation('orders');
+    }
+}
+```
+
+When you use dependency injection in the Active Record model, you need to create the Active Record instance using 
+the factory.
+
+```php
+/** @var \Yiisoft\Factory\Factory $factory */
+$user = $factory->create(User::class);
+```
+
+To create `ActiveQuery` instance you also need to use the factory to create the Active Record model.
+
+```php
+$userQuery = new ActiveQuery($factory->create(User::class)->withFactory($factory));
+```
+
+## Factory Parameter In The Constructor
+
+Optionally, you can define the factory parameter in the constructor of the Active Record class.
+
+```php
+use Yiisoft\ActiveRecord\ActiveQueryInterface;
+use Yiisoft\ActiveRecord\ActiveRecord;
+use Yiisoft\ActiveRecord\Trait\FactoryTrait;
+
+#[\AllowDynamicProperties]
+final class User extends ActiveRecord
+{
+    use FactoryTrait;
+
+    public function __construct(Factory $factory, private MyService $myService)
+    {
+        $this->factory = $factory;
+    }
+
+    public function getMyService(): MyService
+    {
+        return $this->myService;
+    }
+}
+```
+
+This will allow to create the `ActiveQuery` instance without calling `ActiveRecord::withFactory()` method.
+
+```php
+$userQuery = new ActiveQuery($factory->create(User::class));
+```
