Instance name date format

Support

Hi Guys,

Just wondering if there is a way to change the date format for the instance name of a referenced entity on a table.

e.g. from above to just yyyy-MM-dd format

Hi,

this is possible. What you have to do is to use the @NamePattern with a method reference where you define the format for your date. I’ve created an example for this common case:

cuba-example-l10n-date-instancename

CUBA example that shows how to display localized values for dates in the instance name (@NamePattern) of an entity.

To do that the @NamePattern annotation accepts also method references:
@NamePattern("#getCaption|birthday") which allow to delegate the actual String representation to the method getCaption.

Customer entity


@NamePattern("#getCaption|name,birthday")
@Table(name = "CELDI_CUSTOMER")
@Entity(name = "celdi$Customer")
public class Customer extends StandardEntity {
    private static final long serialVersionUID = 1561640237605049941L;

    @Column(name = "NAME")
    protected String name;

    @Temporal(TemporalType.DATE)
    @Column(name = "BIRTHDAY")
    protected Date birthday;

    @Composition
    @OnDelete(DeletePolicy.CASCADE)
    @OneToMany(mappedBy = "customer")
    protected List<Order> orders;

    // ... getters & setters

    public String getCaption() {
        return name + " - " + formatDate(birthday);
    }

    private String formatDate(Date orderDate) {
        return AppBeans.get(DatatypeFormatter.class).formatDate(orderDate);
    }

}

Resulting application

l10n-date-instancename
