I have a Symfony project that is using the DoctrineMigrations bundle, and I have a really simple question: When I run a migration (e.g., when I'm pushing an update to production), how can I insert data to the database?

For example: I have an Entity which is the type of an add. The entity is:

```
private $addType; // String
private $type1;   // Boolean
private $type2;   // Boolean
private $type3;   // Boolean

```

I add another field (`$type4`), and I want to add a new record to the database, with this values:

```
$addType = 'Type number 4';
$type1 = false;
$type2 = false;
$type3 = false;
$type4 = true;

```

How can this be done with DoctrineMigrations? Is it possible?
