Reference key not displayed in related data

Yes I did:

In the GET route I need to enrich my record to add the userEmail

router.get('/places/:place_id/relationships/contracts', (request, response, next) => {
  const place_id = request.params.place_id;
  const limit = parseInt(request.query.page.size, 10) || 20;
  const offset = (parseInt(request.query.page.number, 10) - 1) * limit;
  const recordsGetter = new RecordsGetter(models.contracts);
  const where = { place_id };

  // find the buildingEquipments for the requested page and page size
  const findAll = models.contracts.findAll({
    where,
    offset,
    limit,
  });

  // count all buildingEquipments for pagination
  const count = models.contracts.count({ where });

  // resolve the two promises and serialize the response
  Promise.all([findAll, count])
    .then(([contractsFound, contractsCount]) => {
      const recordsWithUser = contractsFound.map(record => {
        record.userEmail = request.user.email;
        return record;
      });
      return recordsGetter.serialize(recordsWithUser, { count: contractsCount });
    })
    .then((recordsSerialized) => response.send(recordsSerialized))
    .catch(next);
});

In the POST route I had to do that in order to prevent a “permission denied” error when I create a contract within a place

router.post('/places/:place_id/relationships/contracts', (req, res, next) => {
  res.sendStatus(200);
});
