Configurable and user-friendly map widgets for GeoDjango fields

Django Map Widgets

Django Map Widgets is a package that provides highly configurable, pluggable, and user-friendly map widgets for GeoDjango form fields. It simplifies the integration of interactive maps into GeoDjango applications, enhancing the overall development experience.

The primary goal of Django Map Widgets is to bridge the gap between powerful GeoDjango functionality and user-friendly map interactions, creating a more accessible and enjoyable experience for both developers and end-users of GeoDjango-powered applications.

Usage

Django Admin Usage

from django.contrib.gis.db import models
import mapwidgets


class CityAdmin(admin.ModelAdmin):
    formfield_overrides = {
        models.PointField: {"widget": mapwidgets.GoogleMapPointFieldWidget}
    }

Django Forms Usage

from mapwidgets.widgets import GoogleMapPointFieldWidget, MapboxPointFieldWidget


class CityForm(forms.ModelForm):
    class Meta:
        model = City
        fields = ("coordinates", "city_hall")
        widgets = {
            'coordinates': GoogleMapPointFieldWidget,
            'city_hall': MapboxPointFieldWidget,
        }

When the map widgets are used in Django web views with forms, Remember to include {{ form.media }} template tag in the view templates.

Settings

The JavaScript map rendering behavior of the widgets can be customized by providing MAP_WIDGETS config in the project’s settings file. For detailed guidance on map customization options, check the settings guide.

GOOGLE_MAP_API_KEY = os.getenv("GOOGLE_MAP_API_KEY")
MAPBOX_ACCESS_TOKEN = os.getenv("MAPBOX_ACCESS_TOKEN")

MAP_WIDGETS = {
    "GoogleMap": {
        "apiKey": GOOGLE_MAP_API_KEY,
        "PointField": {
            "interactive": {
                "mapOptions": {
                    "zoom": 15,  # set initial zoom
                    "streetViewControl": False,
                },
                "GooglePlaceAutocompleteOptions": {
                    "componentRestrictions": {"country": "uk"}
                },
            }
        }
    },
    "Mapbox": {
        "accessToken": MAPBOX_ACCESS_TOKEN,
        "PointField": {
            "interactive": {
                "mapOptions": {"zoom": 12, "center": (51.515618, -0.091998)},
                "markerFitZoom": 14,
            }
        },
    },
    "Leaflet": {
        "PointField": {
            "interactive": {
                "mapOptions": {
                    "zoom": 12,
                    "scrollWheelZoom": False
                }
            }
        },
        "markerFitZoom": 14,
    }
}

JQuery Requirement

jQuery is required for Django Map Widgets to function in regular Django views. However, if the widgets is being used within the Django Admin, jQuery does not need to be provided separately. Any map widget class can be configured as described in the documentation, and they will work out of the box.

Preferable jQuery version is 3.7-slim.

Support

Django Map Widgets offers two types of widgets:

1. Interactive (Dynamic) Widgets: These widgets allow users to interact with the map, such as clicking to set a location or dragging a marker. They are ideal for data input and editing scenarios.

2. Static (Read-only) Widgets: These widgets display map data in a non-interactive format. They are useful for presenting location information without allowing modifications.
