Nested trial and error in if-else condition

Using Rails 3.2, I have the following:

g = Geocoder.search(address)

# if no address found, geocode with latitude and longitude
if g.empty?
  g = Geocoder.search(latitude, longitude)
  if g.empty?
    log.info "Geocode failed for #{latitude}, #{longitude}"
  end
else
  ---save---
end

If the first geocoding with address fails, it will try latitude and longitude. If still fails, then it logs error, else it will save.

Is this a good way to write this code?

Some notes:

• g: use meaningful names.

• Don't mix code with parentheses and without.

• Check the pattern Object#presence.

• # if no address found, ...: declarative code makes this kind of comments unnecessary.

I'd write:

results = Geocoder.search(address).presence || Geocoder.search(latitude, longitude)
if results.present?
  # save
else
  log.info("Geocode failed for addr='#{search}' and coords=#{latitude}/#{longitude}")
end
