Is it possible to get latitude and longitude values in the controller when using geocoder gem in rails?
What am currently doing for getting all nearby location is pass the location name like below.
event_address = Event.near(location, 15, order: 'distance')
So is there a way to fetch the lat and lng which was used for the above requested location for using later in subsequent requests for same location?
@latitude= #some method
@longitude= #some_method
回答1:
Geocoder.coordinates(location)
for eg : Geocoder.coordinates("25 Main St, Cooperstown, NY")
returns [42.700149, -74.922767]
回答2:
try with Event.geocoded OR
you can use coordinates method of geocoder.
Ex.
Geocoder.coordinates("Your location goes here")
Its return array containing latitude and longitude
