How to change values in Grid because of data relation

Vaadin 6 / 7 / 8 Framework Data Binding
1

Good Morning from Germany,
i’m not so experienced so please forgive if the solution is obvious.
In my case we have a relation in Database, displayed by foreign keys, for example the object customer and ticket. In our java code the customer ID is a attribute of the ticket object.
Out target is to display the full name of the customer not the customerID (in a Grid). For Example in JavaFX it can be solved by using a cellvaluefactory, does vaadin have something similair or how i can solve this problem?

Hi,

You can use a lambda expression:

grid.addColumn(ticket -> customerService.getOne(ticket.getCustomerId()).setCaption("Customer name");

with customerService is your service or repository to retrive your customer by Id.
(It will display customer.toString(), you can also call getFullName())
