django_2gis_maps is a simple application that provides the basic hooks into google maps V3 api for use in Django models from Django version 1.11+.

Starting with django_2gis_maps version (0.7.0), Django 1.11+ is required because Django changed their widget template rendering system. Version 0.8.0 supports Django 2.0+, and as such removes support for Python 2.7

I'm using this to allow someone from the admin panels to type a freeform address, have the address geocoded on change and plotted on the map. If the location is not 100% correct, the user can drag the marker to the correct spot and the geo coordinates will update.

INSTALLATION

• pip install git+https://github.com/NursErgesh/django_2gis_maps.git
• pip install django_2gis_maps

USAGE:

• include the django_2gis_maps app in your settings.py

• create a model that has both an address field and geolocation field

  from django.db import models
  from django_2gis_maps import fields as map_fields
  
  class Rental(models.Model):
      address = map_fields.AddressField(max_length=200)
      geolocation = map_fields.GeoLocationField()

• in the admin.py include the following as a formfield_override

  from django.contrib import admin
  from django_2gis_maps.admin import DoubleGisAdmin
  
  class RentalAdmin(DoubleGisAdmin):
      multiple_markers = False        # Here is your option

• in template include {% load doublegis %} and use {% render_map instanse.get_location %} wherever you need

That should be all you need to get started.

I also like to make the geolocation field readonly in the admin so a user (myself) doesn't accidentally change it to a nonsensical value. There is validation on the field so you can't enter an incorrect value, but you could enter something that is not even close to the address you intended.

When you're displaying the address back to the user, just request the map using the geocoordinates that were saved in your model. Maybe sometime when I get around to it I'll see if I can create a method that will build that into the model.
