# Constructor Properties

There are a few properties you can instantiate the **ActiveEntity** with or set them afterwards that affect operation. Below you can see a nice chart for them:

| Property           | Type    | Required | Default                          | Description                                                                                                       |
| ------------------ | ------- | -------- | -------------------------------- | ----------------------------------------------------------------------------------------------------------------- |
| `queryCacheRegion` | string  | false    | `#entityName#.activeEntityCache` | The name of the secondary cache region to use when doing queries via this entity                                  |
| `useQueryCaching`  | boolean | false    | false                            | To enable the caching of queries used by this entity                                                              |
| `eventHandling`    | boolean | false    | true                             | Announce interception events on *new()* operations and *save()* operations: *ORMPostNew, ORMPreSave, ORMPostSave* |
| `useTransactions`  | boolean | false    | true                             | Enables ColdFusion safe transactions around all operations that either save, delete or update ORM entities        |
| `defaultAsQuery`   | boolean | false    | false                            | The bit that determines the default return value for `list(), executeQuery()` as query or array of objects        |

Here is a nice example of calling the `super.init()` class with some of these constructor properties.

{% code title="User.cfc" %}

```javascript
component persistent="true" table="users" extends="cborm.models.ActiveEntity"{

    function init(){

        setCreatedDate( now() );

        super.init( useQueryCaching=true, defaultAsQuery=false );

        return this;
    }

}
```

{% endcode %}

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://coldbox-orm.ortusbooks.com/active-record/constructor-properties.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
