For a blog app, I have sub collection for each locale. I want to update a slug on parent collection based on blog title on sub locale collection. How to achieve this using callbacks ?
Super late but:
In the callback you have a context and you can access the dataSource from there. You can use it to update data as you see fit.
Or you could achieve the same using a cloud function
