Embrace the power of perpetual movement in an ember concurrency task without hindrance

if (isEmpty(contactData) || isEmpty(get(contactData, 'emails'))) {
  contactData = yield store.findRecord('contact', contactId);
}

if (isEmpty(contactData) || isEmpty(get(contactData, 'emails'))) {
  flashMessages.danger(i18n.t('email.cpq_document_email_missing'));
  return false;
}

The second block is triggered while the promise is still processing and I encounter an error. Shouldn't it pause execution until the promise is fulfilled?

The promise eventually completes successfully with no issues on subsequent runs.

Answer №1

If you are working with ember-data, you might come across a situation where the findRecord function retrieves a cached record. This outcome is influenced by whether the record has been previously loaded (potentially from a prior findRecord, findAll, or query in another route) and how the ember-data adapter is set up: check out the shouldBackgroundReloadRecord and shouldBackgroundReloadAll methods on the adapter, which default to returning true. When these methods return true, the cached record is immediately provided, but the record(s) will also be fetched again in the "background."
