关系中的Sequelize Eager Load属性

Question

我的模型看起来像这样：

let Family = sequelize.define('Family', {
   name: { type: DataTypes.STRING, allowNull: false }});
let Person = sequelize.define('Person', {
   firstName: { type: DataTypes.STRING, allowNull: false },
   lastName: { type: DataTypes.STRING, allowNull: false }});
let  PersonFamily = sequelize.define('PersonFamily', {
   extraInfo: { type: DataTypes.JSONB }});
let  Relationship = sequelize.define('Relationship', {
  name: { type: DataTypes.STRING, allowNull: false }});

Relationship.hasMany(PersonFamily);
PersonFamily.belongsTo(Relationship, { foreignKey: { allowNull: false } });
Person.belongsToMany(Family, { through: PersonFamily, as: 'families' });
Family.belongsToMany(Person, { through: PersonFamily, as: 'members' });

我希望将所有成员和他们的关系拉出所有家庭。我试过这个：

Family.findById(fid,{include: [{model:Person ,as: 'members'}]} 
//works but does not pull the relationship name

和这个

Family.findById(fid,{include: [{model:Person ,as: 'members', include: PersonFamily}]} 
//does not work ... error

任何想法我怎样才能拉出关系名称？
