User Journey:
1. Visit /generate/ endpoint
2. Allow browser location access
3. System generates unique link with coordinates
4. Share link with intended recipient
5. Recipient clicks link and allows location access
6. Interactive map displays both locations
7. Real-time distance calculation and display
# Simplified workflow
def generate_location_link(request):
# Capture user geolocation
latitude = request.POST.get('latitude')
longitude = request.POST.get('longitude')
# Generate unique sharing link
unique_id = generate_unique_id()
# Store location data securely
LocationShare.objects.create(
unique_id=unique_id,
latitude=latitude,
longitude=longitude,
created_at=timezone.now()
