Sort by smart field that includes value from a belongsTo relationship

Context: As a user I want to be able to sort records based on a smart field where the smart field includes data from the current record's parent.
Example: Here I have a model orders that has a belongsTo relationship with the customers model.
I have a smart field in the orders model called customer email that returns the value of the parent customer's email field. I want to sort the orders by the customer email smart field.


const { collection } = require('forest-express-sequelize');
const models = require('../models');
collection('orders', {
actions: [],
fields: [{
field: 'customer email',
get: (order) => models.customers
.then((customer) =>,
isSortable: true,
segments: [],
router.get('/orders', permissionMiddlewareCreator.list(), (request, response, next) => {
if (request.query.sort.includes('customer email')) {
request.query.sort = request.query.sort.includes('-') ? '' : '';
