This app makes it easy to display a map for given address in django templates. No API keys, manual geocoding, html/js copy-pasting or django model changes is needed.
The license is MIT.
Installation
pip install geopy pip install django-easy-maps
Then add ‘easy_maps’ to INSTALLED_APPS and run ./manage.py syncdb (or ./manage.py migrate easy_maps if South is in use)
Usage
This app provides an easy_map template tag:
{% easy_map <address> [<width> <height>] [<zoom>] [using <template_name>] %}
Examples:
{% 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 %}
Customization
If the default map template is not sufficient then custom map template can be used. Examples:
{% easy_map address using 'map.html' %}
{% easy_map address 200 300 5 using 'map.html' %}
The template will have ‘map’ (it is the easy_maps.models.Address instance), ‘width’, ‘height’ and ‘zoom’ variables. The outer template context is passed to rendered template as well.
The default template can be found here: https://bitbucket.org/kmike/django-easy-maps/src/tip/easy_maps/templates/easy_maps/map.html
You can start your own template from scratch or just override some blocks in the default template.
Please refer to http://code.google.com/apis/maps/documentation/javascript/ for detailed Google Maps JavaScript API help.
Address model
easy_maps.models.Address model has the following fields:
address - the requested address
computed_address - address returned by geocoder
longtitude
latitude
geocode_error - True if geocoder wasn’t able to handle the address
Admin address preview
django-easy-maps provides basic widget that displays a map under the address field. It can be used in admin for map previews. Example usage:
from django import forms
from django.contrib import admin
from easy_maps.widgets import AddressWithMapWidget
from firms.models import Firm
class FirmAdmin(admin.ModelAdmin):
class form(forms.ModelForm):
class Meta:
widgets = {
'address': AddressWithMapWidget({'class': 'vTextField'})
}
admin.site.register(Firm, FirmAdmin)
