Play framework 2.0 Java - モデルエラーとinitial-data.ymlの定義

Question

私は自分のモデルを構築し、initial-data.ymlを使ってそれを設定しようとしていました。

ここにある：

#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 

とモデルを記述する別のJavaファイル：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); 
} 

Artist.java -

@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; 
    } 

} 

そして、私を実行していますアプリは私に次の例外を与えます：

これはどこから来るのか分かりません。私は基本的に私のコードをZenTaskサンプルに基づいています。それは動作しますが。

誰かがアイデアを持っていますか？

おかげ

Answer 1

あなたはGlobal.javaでEbean.saveのための正しい順序を持っていることを確認してください。上記の例から、レコードを保存する前にアーティストを保存すると思います
