sails js多对多关联不起作用

// Student.js
module.exports = {
  attributes: {
    name: {
      type: 'string',
      required: true
    },
    courses: {
      collection: 'Course',
      via: 'students',
      dominant: true
    }
  }
};

// Course.js
module.exports = {
  attributes: {
    name: {
      type: 'string',
      required: true
    },
    students: {
      collection: 'Student',
      via: 'courses'
    }
  }
};

// 创建学生和课程
Student.create({ name: 'John', courses: [1, 2, 3] }).exec((err, student) => {
  if (err) {
    console.error(err);
    return;
  }
  console.log('Created student:', student);
});

Course.create({ name: 'Math', students: [1, 2] }).exec((err, course) => {
  if (err) {
    console.error(err);
    return;
  }
  console.log('Created course:', course);
});

// 查询学生及其所选课程
Student.findOne({ name: 'John' }).populate('courses').exec((err, student) => {
  if (err) {
    console.error(err);
    return;
  }
  console.log('Student:', student);
  console.log('Courses:', student.courses);
});

// 查询课程及其学生
Course.findOne({ name: 'Math' }).populate('students').exec((err, course) => {
  if (err) {
    console.error(err);
    return;
  }
  console.log('Course:', course);
  console.log('Students:', course.students);
});
