failed to find geopoint field

I have seperate fields of latitude and longitude (lat and lng) in my django model. I want to use GeoPoint field but getting error failed to find geopoint field.

In my models file , I have added function: @property def type_to_string(self): return { 'lat': self.lat, 'lon': self.lng }

Created GeoPointField in documents.py loc1 = fields.GeoPointField(attr=‘type_to_string’)

Now when I run the query s1 = LocationDocument.search().filter( ‘geo_distance’, distance=‘1000m’, loc1={“lat”: “40”, “lon”: “-74”} )
s1 = s1.execute()

I get error here. Any help where I am going wrong.

This looks like your index wasn’t created with proper mappings in place, you need to explicitly create the index before indexing any data into it.

In elasticsearch dsl you do it by calling the init() classmethod on your Document subclass.

Hope this helps!
