Playframework 2.0 Play framework 2.0 Java-定义模型错误和initial-data.yml

我试图构建自己的模型，并通过initial-data.yml填充它

这是：

#Artists

artists:

    - !!models.Artist
        id: 1
        name: orelsan
        occupation: chanteur

#Records
records:
    - !!models.Record
        id: 1
        title: Le chant des sirenes
        vinylType: La classe
        pressInfo: a
        style: rap
        hits: 11
        artist: !!models.Artist
                    id: 1

以及描述模型的不同java文件：Record.java-

@Entity
public class Record extends Model{

    @Id
    public Long id;

    @Required
    public String title;

    public String vinylType;

    public String pressInfo;

    public String style;

    @ManyToOne
    public Artist artist;

    public int hits;//Number of time played-consulted

    /**
     * Generic query helper for entity record with id Long
     */
    public static Finder<Long,Record> find = new Finder<Long, Record>(Long.class, Record.class);
}

我真的不明白这是从哪里来的。我的代码基本上基于ZenTask示例。尽管它会起作用

有人有主意吗

谢谢

请确保您在Global.java中订购了正确的Ebean.save。从上面的示例中，我希望您在录制之前先保存Artist

确保您在Global.java中保存Ebean.save的顺序正确。从你上面的例子来看，我希望你在录制之前先保存艺术家

@Entity
public class Artist extends Model{

    @Id
    public Long id;

    @Required
    public String name;

    @Required
    public String occupation;

    /**
     * Generic query helper for entity Computer with id Long
     */
    public static Finder<Long,Artist> find = new Finder<Long, Artist>(Long.class, Artist.class);

    public String toString(){
        return name;
    }

}
