Frappe Framework version 14 - Inverted latitude and longitude for Map View

Frappe Framework Customization

When creating latitude and longitude fields, the map view show wrong pin position because Geolocation JSON wants the point defined has [longitude,latitude] instead of [latitude,longitude].

Original code.

def create_gps_markers(coords):
	"""Build Marker based on latitude and longitude."""
	geojson_dict = []
	for i in coords:
		node = {"type": "Feature", "properties": {}, "geometry": {"type": "Point", "coordinates": None}}
		node["properties"]["name"] = i.name
		node["geometry"]["coordinates"] = [i.latitude, i.longitude]
		geojson_dict.append(node.copy())

	return geojson_dict

Edited code (inverted latitude and longitude)

def create_gps_markers(coords):
	"""Build Marker based on latitude and longitude."""
	geojson_dict = []
	for i in coords:
		node = {"type": "Feature", "properties": {}, "geometry": {"type": "Point", "coordinates": None}}
		node["properties"]["name"] = i.name
		node["geometry"]["coordinates"] = [i.longitude, i.latitude]
		geojson_dict.append(node.copy())

	return geojson_dict

We use leaflet which uses lat-long instead of long-lat (GeoJSON)

TIL :slight_smile:

Hi, I understand the usage of leaflet, I use the same library in other projects.
The problem is that the points where loaded with lat-lon coordinates inverted in the map view automatically generated by frappe framework when a doctype has latitude and longitude fields.

Please check the referenced code in my post that is related to version-14 production branch.

Regards,
Diego

I can confirm this. the get_coords sql should already reverse lat and lng! V14.
