# Own events {#ownevents}

The concept of the calendarize extension is the creation of own models and tables that should be part of the calendar output.

## Configuration {#configuration}

Calendarize needs a configuration to handle your own model.
A common practice is to store this in a static function (e.g. `Classes/Register.php`).

**EXT:some_extension/Classes/Register.php**

```php
$configuration = [
    // Unique Key for the register (e.g. you Extension Key + "Event")
    'uniqueRegisterKey' => 'MyEvent',
    // Title for your events (this is shown in the FlexForm configuration of the Plugins)
    'title'             => 'My Event',
    // Name of your model
    'modelName'         => \HDNET\MyExtension\Domain\Model\MyEvent::class,
    // Partials identifier (HTML) for your event (in most cases unique)
    'partialIdentifier' => 'MyEvent',
    // Table name of your event table
    'tableName'         => 'tx_myextension_domain_model_myevent',
    // If true, your event requires at least one event configuration
    'required'          => true,

    // [OPTIONAL] All classNames used for the extended models
    'subClasses'        => array of classnames,
    // [OPTIONAL] Field name of the configurations, default is 'calendarize' (recommended)
    'fieldName'         => 'calendarize'
];
```

This configuration is then registered to calendarize by adding it to your `ext_localconf.php`:

**EXT:some_extension/ext_localconf.php**

```php
$configuration = [...];
\HDNET\Calendarize\Register::extLocalconf($configuration);
```

Additionally, you need to add the TCA configuration for the event configuration and information field:

**EXT:some_extension/Configuration/TCA/Overrides/\<tx_extension_domain_model_event>.php**

```php
\HDNET\Calendarize\Register::createTcaConfiguration($configuration);
```

### Change preview count {#change-preview-count}

To modify the amount of items shown in the preview you can change the amount in the TCA override.
10 items are displayed by default.

**EXT:some_extension/Configuration/TCA/Overrides/\<tx_extension_domain_model_event>.php**

```php
$GLOBALS['TCA']['tx_myextension_domain_model_myevent']['columns']['calendarize_info']['config']['parameters']['items'] = 25;
```
