Add validation to a smart field edition
Context: I want to make sure that my users can only enter a value satisfying a certain set of conditions when editing a smart field.
Here I'm working on a collection customers
and the smart field 'must-be-kuku'
should only accept the value kuku
.
forest/customers.js
const { collection } = require('forest-express-sequelize');
const models = require('../models');
// This file allows you to add to your Forest UI:
// - Smart actions: <https://docs.forestadmin.com/documentation/reference-guide/actions/create-and-manage-smart-actions>
// - Smart fields: <https://docs.forestadmin.com/documentation/reference-guide/fields/create-and-manage-smart-fields>
// - Smart relationships: <https://docs.forestadmin.com/documentation/reference-guide/relationships/create-a-smart-relationship>
// - Smart segments: <https://docs.forestadmin.com/documentation/reference-guide/segments/smart-segments>
collection('customers', {
actions: [],
fields: [
{
field: 'must-be-kuku',
type: 'String',
get(customer) {
return 'kuku';
},
set(customer, value) {},
},
],
segments: [],
});
At the route level I need to check the user input from the edit form in the UI and check the value that has been entered into the field 'must-be-kuku'
.
routes/customers.js
const express = require('express');
const { PermissionMiddlewareCreator } = require('forest-express-sequelize');
const { customers } = require('../models');
const router = express.Router();
const permissionMiddlewareCreator = new PermissionMiddlewareCreator(
'customers'
);
// Update a Customer
router.put(
'/customers/:recordId',
permissionMiddlewareCreator.update(),
(request, response, next) => {
if (request.body.data.attributes['must-be-kuku'] !== 'kuku') {
return response.status(403).send('should have been kuku!');
}
next();
}
);
module.exports = router;
