django-easy-maps: A Python repository from dkopitsa

django-easy-maps

This app makes it easy to display a map for any given address in django templates. No manual geocoding, html/js copy-pasting or Django model changes are needed.

Authored by Mikhail Korobov, and some great contributors.

Installation

First install the module, preferably in a virtual environment. It can be installed from PyPI:

pip install django-easy-maps

Setup

You'll need to add easy_maps to INSTALLED_APPS in your project's settings.py file:

INSTALLED_APPS += [
    'easy_maps',
]

Then run ./manage.py migrate to create the required database tables.

Configuration

The only mandatory configuration is the EASY_MAPS_GOOGLE_KEY variable:

EASY_MAPS_GOOGLE_KEY = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ___0123456789'

If you need a place to center the map at when no address is inserted yet, add the latitude and longitude to the EASY_MAPS_CENTER variable in your settings.py like the following:

EASY_MAPS_CENTER = (-41.3, 32)

Please see the example application. This application is used to manually test the functionalities of this package. This also serves as a good example.

You need Django 1.8 or above to run that. It might run on older versions but that is not tested.

Usage

First of all, load the easy_map_tags in every template where you want to use it:

{% load easy_maps_tags %}

Use:

{% easy_map <address> [<width> <height>] [<zoom>] [using <template_name>] %}

For example:

{% load easy_maps_tags %}

<!-- Default map with 300x400 dimensions -->
{% easy_map "Russia, Ekaterinburg, Mira 32" 300 400 %}

<!-- Variable address, custom detail level and custom template -->
{% easy_map address 200 200 5 using "map.html" %}

The coordinates for map will be obtained using google geocoder on first access. Then they'll be cached in DB. Django's template caching can be used later in order to prevent DB access on each map render:

{% load easy_maps_tags cache %}

{% cache 600 my_map firm.address %}
    {% easy_map firm.address 300 400 %}
{% endcache %}

Templates

If the default map template is not sufficient then a custom map template can be used. For example:

{% easy_map address using "map.html" %}
{% easy_map address 200 300 5 using "map.html" %}

The template will have map (easy_maps.Address instance auto-created for passed address on first access), width, height and zoom variables. The outer template context is passed to the rendered template as well.

You can start your own template from scratch or just override some blocks in the default template.

Please refer to https://developers.google.com/maps/documentation/javascript/ for detailed Google Maps JavaScript API help.

Widgets

django-easy-maps provides a basic widget that displays a map under the address field. It can be used in the admin for map previews. For example:

from django import forms
from django.contrib import admin

from easy_maps.widgets import AddressWithMapWidget

from .models import Firm

class FirmAdmin(admin.ModelAdmin):
    class form(forms.ModelForm):
        class Meta:
            widgets = {
                'address': AddressWithMapWidget({'class': 'vTextField'})
            }

admin.site.register(Firm, FirmAdmin)

address field should be either a CharField or TextField.
