`puts` converts ruby object into string by invoking to_s method on object.
The default to_s prints the object's class and an encoding of the object id. In order to print human readable form of object use inspect
locs = Location.find_by_sql('select * from locations')
Location Load (0.5ms) select * from locations
Puts Object internally invokes to_s method on object to print
locs.each do |l|
# it calls to_s method on object
puts l
end
#<Location:0x000000055bb328>
#<Location:0x000000055bb058>
puts object followed by subsequent invoke of inspect method outputs readable object
locs.each do |l|
puts l.inspect # prints actual object
end
