Question

我正在使用节点js并使用claudia-api-builder作为框架在AWS中启动API来构建无服务器应用程序。

在app.js文件中，我将所需的api称为

driver.find_element_by_xpath("//*[contains(local-name(), 'button') and contains(@class, 'gprospect_linkedin_button')]").click()

下面是我的代码：

const ApiBuilder = require('claudia-api-builder');
const api = new ApiBuilder();
module.exports = api;

api.post('/api/auth/validatephonenumber', async function (request) 
{
    return new Promise((resolve, reject) => {
        index.loadDatabase().then((db) => {
            resolve(loginController.validatePhonenumber(db, request));
        });
    });
});

我试图将EmailRegistration表的emailregistrationid添加到ContactDetails表中作为外键引用。我正在将sequelize与mysql，nodejs配合使用以实现所需的结果。但是，我遇到了以下错误：

未处理的拒绝SequelizeForeignKeyConstraintError：无法添加或更新子行：外键约束失败（async function validatePhonenumber(db, request) { return new Promise( async (resolve, reject) => { let emailid; await db.EmailRegistration.sync().then(function () { emailid = db.EmailRegistration.findOne({ where: { email: { [Op.eq]: mailid } }, attributes: ['id'], }); }); if (emailid != null) { console.log(`email id: ${emailid.id}`); await db.ContactDetails.sync().then(function () { db.ContactDetails.findOrCreate({ where: { contactnumber: phnum }, defaults: { EmailRegistrationId: emailid.id }, }).spread((contactdetails, created) => { console.log(`contactdetails: ${contactdetails}`); if (contactdetails !== null) { resolve({ statuscode: indexController.statusCode.statusOK, contactdetails: contactdetails }) } else { reject({ statuscode: indexController.statusCode.InternalServerError, message: 'phone number not created' }); } }); }); }; }); }。inmeeydb，CONSTRAINT ContactDetails外部键（ContactDetails_ibfk_1）参考{ {1}}（EmailRegistrationId）在删除CASCADE时在更新CASCADE上

以下是我的EmailRegistration模型文件：

EmailRegistration

下面是我的Contactdetails模型文件：

id

我试图在两个表中都按以下方式更改代码，但没有任何效果。

const moment = require('moment');

module.exports = (sequelize, DataTypes) => {
const EmailRegistration = sequelize.define(
'EmailRegistration',
{
  id: {
    type: DataTypes.UUID,
    primaryKey: true,
    allowNull: false,
    defaultValue: DataTypes.UUIDV4,
  },
  email: {
    type: DataTypes.STRING(50),
    allowNull: false,
  },
  password: {
    type: DataTypes.STRING,
    allowNull: false,
    validate: { min: 6 },
  },
  createdAt: {
    type: DataTypes.DATE,
    get() {
      return moment.utc(new Date(), 'DD/MM/YYYY h:mm a').format('DD/MM/YYYY h:mm a');
    },
  },
  updatedAt: {
    type: DataTypes.DATE,
    defaultValue: null,       
  },
},
{
  freezeTableName: true,
}
);

EmailRegistration.associate = function (models) {
    EmailRegistration.hasOne(models.ContactDetails,
        { foreignKey: 'EmailRegistrationId' }
    );
};

return EmailRegistration;
};

无法分析如何解决此问题。当我将nodejs与expressjs一起使用且没有问题时，此方法工作正常。它无法在ContactDetails表中标识EmailRegistrationId（查询中缺少），并将输出显示为

const moment = require('moment');

module.exports = (sequelize, DataTypes) => {
const ContactDetails = sequelize.define(
'ContactDetails',
{
  id: {
    type: DataTypes.UUID,
    primaryKey: true,
    allowNull: false,
    defaultValue: DataTypes.UUIDV4,
  },
  contactnumber: { type: DataTypes.STRING(13), allowNull: false },
  isverified: { type: DataTypes.BOOLEAN, defaultValue: false },
  createdAt: {
    type: DataTypes.DATE,
    get() {
      return moment.utc(new Date(), 'DD/MM/YYYY h:mm a').format('DD/MM/YYYY h:mm a');
    },
  },
  updatedAt: {
    type: DataTypes.DATE,
    defaultValue: null,        
  },
},
{
  indexes: [{ fields: ['contactnumber'], unique: true }],
},
{
  freezeTableName: true,
}
);

ContactDetails.associate = function(models) {
ContactDetails.belongsTo(models.EmailRegistration, {
  onDelete: 'CASCADE',
  hooks: true,
  foreignKey: { allowNull: false },
});
};   


return ContactDetails;
};

您需要更新关联的配置。 ContactDetails模型现在将具有一个名为emailregistrationid

的字段

EmailRegistration.associate = function (models) {
  EmailRegistration.hasMany(models.ContactDetails);
};

ContactDetails.associate = function(models) {
  ContactDetails.belongsTo(models.EmailRegistration, {
    onDelete: 'CASCADE',
    hooks: true,
    foreignKey: {
      name: 'emailregistrationid'
      allowNull: false
    },
  });
}

ContactDetails.create({
  ...
  emailregistrationid: <some_valid_emailregistrationid>
})

无法使用Sequelize将ID插入到属于外键引用表的表中
