Question

Hi I would like to import Play framework Java Exension* into a Play framework Model.
In specific I’d like to have in my model:

package models;

// various import
import play.templates.JavaExtensions;

@Entity
public class Product extends Model {
    @PrePersist
    public void save_slug(){
        slug = title.slugify();
    }
}

But I’m receiving following error

The method slugify() is undefined for the type String

What am I doing wrong?

Java extensions are static methods of JavaExtensions class, you can use them as follows:

slug = JavaExtensions.slugify(title);
