How to auto fill latitude and longitude fields in Django2.0.6?

[prateek gupta]

Hi All,

I have created a store address form using Django2.0.6+Mysql+Python3.6.

Currently user has to manually fill latitude and longitude for the store address.

I want to auto-fill both fields once user entered the address.

Below is my current code-

models.py-

class Store(models.Model):
    building = models.ForeignKey(Building, related_name='building', 
    on_delete=models.SET_NULL, blank=True, null=True)
    name = models.CharField(max_length=100)
    postal_code = models.CharField(max_length=6)
    address = models.TextField()
    latitude = models.FloatField(validators=[MinValueValidator(-90.0), 
    MaxValueValidator(90.0)])
    longitude = models.FloatField(validators=[MinValueValidator(-180.0), 
    MaxValueValidator(180.0)])

class Meta:
    managed = False
    db_table = 'store'

admin.py-

class StoreAdmin(admin.ModelAdmin):
    list_display = ('id', 'name', 'postal_code', 'address', 'latitude', 
 'longitude')

Can anyone please help me how to achieve this requirement?

I use pygeocoder.py and something like this!

johnf

class Getlatitudelongitude(dObject):
    ###############################
    #   gmaps.py
    ###############################

    import urllib
    from time import sleep
    import pygeocoder


    key = "here_goes_your_key"

    def location2latlong(self, query, key="here_goes_your_key" ):
        """pass a complete address
        18 Tadlock Place Woodland, CA 95776"""
        """Get the ( latitute, longitude ) coordinates corresponding
        to the query. If something goes wrong return None."""
        import urllib
        from time import sleep
        import pygeocoder

        #output = 'csv'

        #params = { }
        ### The key below was generated by accessing google http://code.google.com/apis/maps/signup.html
        #params[ 'key' ] = 'ABQIAAAALTR1FL24DycBouLv0t9q3xTEP5gmNW-Z6UMR8J4ewevcZqC8sxRRfI_D2-yrCM4YXmAZEPFdIzSijA' #key
        #params[ 'output' ] = output
        #params[ 'q' ] = query

        #params = urllib.urlencode( params )
        #print params
        a_geo_class = pygeocoder.Geocoder()

        try:
            #f = urllib.urlopen( "http://maps.google.com/maps/geo?%s" % params )
            f = a_geo_class.geocode(query)
            response = f.coordinates
            latitude = response[0]
            longitude = response[1]
            #f.close()
            return latitude, longitude
        except pygeocoder.GeocoderError as err:
            return None

It seems for this I need to use API key from google.

Have you heard about this python package- from location_field.models.plain import PlainLocationField?

I tried with this one but getting some issues-

You need access to a service (or data set) which translates addresses to latitude/longitude.

It will depend on your country whether this information is available and/or whether you need to pay for access to that service, and how that service

Which countries will your application cover - maybe with some extra information someone can give you some more details.

There is nothing in django that provides this capability.

Question - why do you need latitude and longitude ?

I am working in Singapore and trying to store details of different merchants of Singapore.

So if any merchant wants to add a new store, I am giving him this option build on Django.

So once he entered his store address, the lat/long fields will be auto-fill and location field will show the map.

The implementation part I have already covered above, you can check what package I am using for this functionality.
