sequelize中的插入问题

Question

用户表：

var user = connection.define('user', {
  id: {
    type: sequelize.INTEGER,
    primaryKey: true,
    autoIncrement: true
  },
  name: {
    type: sequelize.STRING
  },
  age: {
    type: sequelize.INTEGER
  }
}, {
  classMethods: {
    insertData: function(sql, data) {
      this.create({
        name: data.name,
        age: data.age
      }).then(function() {
        console.log("successful insertion");
      });
    }
  }
});

地址表：

var address = connection.define('address', {
  id: {
    type: sequelize.INTEGER,
    primaryKey: true,
    autoIncrement: true
  },
  content: sequelize.TEXT
}, {
  classMethods: {
    associate: function(model) {
      var user = model.user;
      user.hasMany(address);
    },
    insertData: function(data) {
      this.create({
        content: data.content,
        userId: data.id
      }).then(function() {
        console.log("working ");
      });
    }
  }
});  

现在，我如何在用户和地址之间的关系之后创建的表地址的字段userId中插入数据。

直接插入如下所述的字段名称不起作用。

insertData: function(data) {
  this.create({
    content: data.content,
    userId: data.id
  }).then(function() {
    console.log("working ");
  });
}
