sequelize.js:未处理的拒绝SequelizeForeignKeyConstraintError

我试图插入/更新数据到一个postgresql数据库使用以下function:

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); }); } 

我已经看过了我能find的其他所有类似的问题,但是没有一个解决scheme似乎可行。 我不断收到以下错误。

任何帮助将非常感激
