Active Jdbc Associationは動作しません

Question

私はUserとCompetenciaという2つのクラスを持っています。私はそれらの間に関係を作りたいが、それは動作しません。参照：

public class User extends Model{ 

} 

@Table(value = "competencias") 
@BelongsTo(foreignKeyName = "user_id", parent = User.class) 
public class Competencia extends Model{ 

} 

CREATE TABLE competencias(
    id INTEGER NOT NULL DEFAULT NEXTVAL('competencias_id_seq'::regclass), 
    mes CHARACTER(2) NOT NULL, 
    ano CHARACTER(4) NOT NULL, 
    created_at DATE NOT NULL DEFAULT now(), 
    user_id INTEGER NOT NULL, 
    ativo BOOLEAN, 
    CONSTRAINT pk_competencia PRIMARY KEY (id), 
    CONSTRAINT fk_competencia_operador FOREIGN KEY (user_id) REFERENCES public.users (id) MATCH SIMPLE ON UPDATE CASCADE ON DELETE NO ACTION, 
    CONSTRAINT uk_mes_ano UNIQUE (mes, ano) 
) 

CREATE TABLE users(
    id INTEGER NOT NULL DEFAULT NEXTVAL('operadores_id_seq'::regclass), 
    nome CHARACTER VARYING(25) NOT NULL, 
    email CHARACTER VARYING(100) NOT NULL, 
    senha CHARACTER VARYING(120) NOT NULL, 
    nivel INTEGER NOT NULL DEFAULT 4, 
    ativo BOOLEAN, 
    created_at DATE DEFAULT now(), 
    nome_completo CHARACTER VARYING(60) NOT NULL, 
    CONSTRAINT pk_operadores PRIMARY KEY (id), 
    CONSTRAINT unique_login UNIQUE (nome) 
);

コード：私は「

User user = User.findById(usuario.getId()); 
Competencia competencia = new Competencia(); 
competencia.set("id", id); 
competencia.set("mes", String.format("%02d", comboMes.getSelectedIndex())); 
competencia.set("ano", comboAno.getSelectedItem().toString()); 
competencia.set("ativo", checkAtivo.isSelected()); 
**competencia.add(user);** 
if(competencia.isValid()){ 
    if(competencia.saveIt()){ 
    Functions.informacao("Competencia gravada"); 
    labelCodigo.setText(String.format("%04d", competencia.getId())); 
    preparaForm("salvar"); 
    } 
}else{ 
    String message = showInfo(competencia); 
    JOptionPane.showMessageDialog(this, message, "Corrija os erros abaixo:", JOptionPane.ERROR_MESSAGE);  
} 

Answer 1

あなたが規則に従っているため

@BelongsTo(foreignKeyName = "user_id", parent = User.class)

：あなたは、ログ出力を提供しなかったので、本当の問題は、ですが、あなたのモデルCompetenciaが注釈を持たないべきか、まだ分かりません。さらに、有用な情報があるので、最初の行ではなくスタックトレース全体を含めてください。

UPDATE：

あなたのテーブル構造によれば、あなたは1人のユーザーが多くのCompetenciasを持って、一対多の関係を、持っています。

ただし、competenciaに多くのユーザーを追加する：Competenciaユーザーを持っていない

competencia.add(user);

、それは周りの他の方法です！ユーザーには多くの競技会があります。このコードは動作します：他の言葉で

user.add(competencia);

は、あなたが親/子関係を逆転させました。
