[TYPO3-mvc] Object relation - get children

[Henjo Hoeksma | Stylence]

Hi Jan,

You put the relation on your project object.
This means you should delete the customer relation from your project model
and add a relation field projects to your customer model.

Now you can do $project->getCustomers(); after the change you can do what
you really want: get projects based on your aggregate root.

Kind regards,

Henjo

Problems are small because we learned how to deal with them.
Problems are big because we need to learn how to deal with them.
