Search for Nearby Locations
To search for nearby locations, as shown in Figure
9-16
, use the current user's location, obtained by calling the
get_user_location
method in the
UserLocation
class, and then by calling the
locations_within_distance
. The
locations_within_distance
method in
Location
class uses a method called
distance
to return a string value of the
distance between the starting point and the respective location (Listing 9-39).
