Installation

Its simple to install - use this command to upgrade as well:

python setup.py install

Or

easy_install django_gmapsfield

/settings.py

INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    ...
    'gmapsfield', # Make sure to register this
    ...
)

/urls.py

# Note: the following approach is non-standand, while it remains functional
# there are many disadvantages that django 1.3 static file handling will
# correct.

# Add this to serve correct admin js
(r'^admin/gmapsfield/admin/(?P<file>.*)$', 'gmapsfield.views.serve'),

# Optionally symlink this folder to your admin media path

/models.py

from gmapsfield.fields import GoogleMapsField

from django.db import models
from django.contrib import admin

class Test(models.Model):
    map = GoogleMapsField()

    # Can optionally specify defaults via JSON string
    #map2 = GoogleMapsField(default="{ coordinates: [-40, 50], zoom: 10, size: [400, 200] }")

admin.site.register(Test)

/views.py

from demo.map.models import Test

from django.template import RequestContext, loader
from django.http import HttpResponse

def index(request):
    template = loader.get_template("index.html")

    # Grab the first map if one exists - for purposes of example 
    test = (Test.objects.all() and Test.objects.all()[0]) or { "map": { show: "No maps defined" } }

    return HttpResponse(template.render(RequestContext(request, {
        "test": test
    })))

/template.html

<!-- Required to view result in a template -->
{% load gmap %}

<!-- Will display the actual map -->
{{ test.map|show }}

<!-- Includes the necessary scripts on the page, place anywhere, but only once and do not forget! -->
{% gmap_includes %}

Development Notes:

• 1/04/11: Updated path to serve admin.js to be called admin instead of public.
• 1/19/11: Two new settings added GMAP_JQUERY and GMAP_API which are string urls pointing to the respective resources. Fixed bug with dumpdata. Can now set global defaults in models via JSON.
