Question: How to manage related fields

[bordieris]

I have a city class with several attributes: id, name, province, etc...
In a Nova resource form, I'm using a place field to write an address and prepopulate related fields in my resource: address itself, lat, long. Everything works like a charm. But I also have in that form a BelongsTo field, searcheable and prepopulate.
How can I automatically search and select the right city after place address confirmation?
