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

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));
        });
    });
});


下面是我的代码:

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' });
                    }
                });
            });
        };
    });
}


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,我得到以下错误:


  未处理的拒绝SequelizeForeignKeyConstraintError:无法添加或更新子行:外键约束失败(inmeeydbContactDetails,CONSTRAINT ContactDetails_ibfk_1外国密钥(EmailRegistrationId)参考EmailRegistrationid)ON删除级联打开更新级联)


以下是我的EmailRegistration模型文件:

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;
};


以下是我的Contactdetails模型文件:

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;
};


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。

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


无法分析如何解决该问题。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

INSERT INTO `ContactDetails` (`id`,`contactnumber`,`isverified`,`createdAt`,`updatedAt`) VALUES ('52974e07-8489-4101-ab71-6af874903290','+xxxxxxxxx',false,'2018-10-12 08:55:35','2018-10-12 08:55:35');

最佳答案

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>
})
