sequelize.js：未处理的拒绝SequelizeForeignKeyConstraintError

Question

我正在尝试使用以下函数将数据插入/更新到postgresql数据库中：

var updateStudentDataAndReturn = function(req, res, { redirectLink: redirectLink, studentId: studentId }) {
  models.Student.update({
    firstName: req.body.firstName,
    lastName: req.body.lastName,
    phoneNumber: req.body.phoneNumber,
    skypeUsername: req.body.skypeUsername,
    typeOfStudent: req.body.typeOfStudent,
    school: req.body.school,
    expectedYearOfGraduation: req.body.expectedYearOfGraduation,
    TeamId: req.body.TeamId
  }, {
    where: {
      id: studentId
    }
  }).then(() => {
    return models.StudentMajor.destroy({
      where: {
        StudentId: studentId
      }
    })
  }).then(() => {
    return models.StudentSchool.destroy({
      where: {
        StudentId: studentId
      }
    })
  }).then(() => {
    if (!Array.isArray(req.body.major)) {req.body.major = [req.body.major]};
    return req.body.major.forEach((major) => {
      return models.StudentMajor.create({
        StudentId: studentId,
        major: major
      });
    });
  }).then(() => {
    if (!Array.isArray(req.body.school)) {req.body.school = [req.body.school]};
    return req.body.school.forEach((school) => {
      return models.StudentSchool.create({
        StudentId: studentId,
        school: school
      });
    });
  }).then(() => {
    return res.redirect(redirectLink);
  }).catch((err) => {
    console.log('ERROR', err);
  });
}

我已经看过我能找到的其他类似问题，但没有一个解决方案似乎有效。我一直收到以下错误。
