Node.js+；sequelize：同一型号的两个外键

我需要在一个名为DataSurvey的模型中添加两个外键，它们指向另一个名为AppPerson的模型

  DataSurvey.associate = function(models) {
DataSurvey.belongsTo(models.AppPerson); // this should have the name idResponsible
DataSurvey.belongsTo(models.AppPerson); // this should have the name idConcerned  };

我该怎么做

谢谢你的帮助

这很好用

    DataSurvey.belongsTo(models.AppPerson, {as: 'Responsible'});
    DataSurvey.belongsTo(models.AppPerson, {as: 'Concerned'});
