query={{item.latitude}},{{item.longitude}} — and every
Link opens the map at its own Item’s position.
For directions instead of a pin:
api=1 is required in both. No Google API key is needed — these are Maps URLs, not the
Maps API.
Bind coordinates, not place names
query= accepts a place name as well, but a name has spaces in it, and spaces have to arrive as
+ or %20. QRtub does no URL encoding, so a bound place name breaks the link.
Coordinates have no spaces, so they are safe. Store latitude and longitude as their own fields and
bind those.
