问题
I am able to create records in my MySQL DB with sequelize and NodeJS.
But now I am trying to update records in my Database.
I have NodeJS as backend and my DB is MySql. Sequelize is my ORM. In Sequelize 5, I have a couple of classes: WorkOder, User (mechanic), Customer, Client and ExpertiseOffice. My datamodel is not complex, there are only 1:1 relations. A WorkOrder has one customer, one Client and one ExpertiseOffice.
I use Postman to test my api's. With creating a WorkOrder with some Customer fields included the workOrder is created but not the Customer.
My associations file looks like this:
const User = require('../models/user');
const WorkOrder = require('../models/work-order');
const Customer = require('../models/customer');
const Client = require('../models/client');
const ExpertiseOffice = require('../models/expertise-office');
WorkOrder.belongsTo(User, { foreignKey: 'mechanicId' });
WorkOrder.belongsTo(Client, { foreignKey: 'clientId' });
WorkOrder.belongsTo(Customer, { foreignKey: 'customerId' });
WorkOrder.belongsTo(ExpertiseOffice, { foreignKey: 'expertiseOfficeId' });
The WorkOrder model looks like this:
// WORK-ORDER MODEL
const Customer = require('./customer');
const Client = require('./client');
const ExpertiseOffice = require('./expertise-office');
const User = require('./user');
const Sequelize = require('sequelize');
const sequelize = require('../util/database');
const WorkOrder = sequelize.define('workOrders', {
id: {
type: Sequelize.UUID,
allowNull: false,
primaryKey: true,
},
projectNumber: {
type: Sequelize.INTEGER,
allowNull: true,
},
dateInspection: {
type: Sequelize.DATE,
allowNull: true,
},
mechanicId: {
type: Sequelize.UUID,
allowNull: true,
references: {
// User belongsTo WorkOrder 1:1
model: 'User',
key: 'id',
},
},
clientId: {
// Opdrachtgever
type: Sequelize.UUID,
allowNull: true,
references: {
// Client belongsTo WorkOrder 1:1
model: 'Client',
key: 'id',
},
},
customerId: {
// klant
type: Sequelize.UUID,
allowNull: true,
references: {
// Customer belongsTo WorkOrder 1:1
model: 'Customer',
key: 'id',
},
},
expertiseOfficeId: {
type: Sequelize.UUID,
allowNull: true,
references: {
// ExpertiseOffice belongsTo WorkOrder 1:1
model: 'ExpertiseOffice',
key: 'id',
},
},
leakageReason: {
type: Sequelize.STRING,
allowNull: true,
},
status: {
type: Sequelize.STRING,
allowNull: true,
},
// Timestamps
createdAt: Sequelize.DATE,
updatedAt: Sequelize.DATE,
});
module.exports = WorkOrder;
In the front end application only very limited fields are required because the front end user can add information about the customer, client etc. on a later moment.
My WorkOrder controller with the updatre workOrder code (not working properly) is looking like this.
exports.updateWorkOrder = (req, res, next) => {
console.log('####-in the updateWorkOrder endpoint!');
const workOrder = req.body;
console.log('####-put-workorder', workOrder);
WorkOrder.update(
workOrder,
{ where: { id: req.params.id } },
{ include: [User, Customer, Client, ExpertiseOffice] }
)
.then((result) => {
if (result) {
WorkOrder.findByPk(req.params.id).then((result) => {
console.log('####--result', result);
console.log('####-work-order updated!');
res.status(200).json({
message: 'Work order successfully updated!',
data: result,
});
});
}
})
.catch((err) => {
console.log('error', err);
res.status(500).json({
message: 'An error occurred',
err: err,
});
});
};
The workOrder data which is going into the update method looks like this:
####-in the updateWorkOrder endpoint!
####-put-workorder {
id: '29d9795d-ef7f-418e-a479-340cb7ee5509',
projectNumber: '123456',
dateInspection: null,
followupInspection: null,
clientPresent: null,
mechanicId: null,
clientId: '2c611177-48f6-48d2-a2d0-e7f6a93cc16b',
customerId: 'd53f56c7-9954-4e52-b8e2-de4d28229caf',
expertiseOfficeId: null,
leakageReason: 'issue with roof',
visibleWaterDamage: null,
visibleWaterDamagePeriod: null,
buildingType: null,
renovatedYear: null,
status: null,
createdAt: '2020-07-04T07:24:28.000Z',
updatedAt: '2020-07-04T07:25:03.000Z',
user: null,
customer: {
id: 'd53f56c7-9954-4e52-b8e2-de4d28229caf',
name: 'Customer One',
contactPerson: null,
companyName: null,
street: 'Street',
houseNumber: '1',
houseNumberExt: null,
zipCode: '91111',
city: 'LA',
phoneNumber: null
},
client: {
id: '2c611177-48f6-48d2-a2d0-e7f6a93cc16b',
name: 'Roof Inspectors',
contactPerson: null,
email: null,
phoneNumber: 'Roof Inspectors',
street: null,
houseNumber: null,
houseNumberExt: null,
zipCode: null,
city: null,
attribute: null
},
expertiseOffice: null
}
This is the correct updated information from the front end.
Now I don't get an error message from sequelize but the record is not updated. The spooled result looks like this:
####--result workOrders {
dataValues: {

},

}
Can anybody please help me? I have no clue why the records is not updated. Many thanks in advance. Pete
