django-gmapi: A Python repository from atuljain

=========================================================
Django Google Maps API v3 and Static Maps API helper app.
=========================================================


This app allows you to define Google Map and Marker objects in Python.

These objects are designed to be serialized to JSON and parsed by the included
jQuery plugin which converts them to actual Google Map and Marker instances.

They can also be serialized to strings which produces a Static Maps url.

This way you can easily use unobtrusive javascript techniques along with maps.

This project is being developed as one piece of a larger project I'm working
on. So functionality will be added as I need it. In particular, the jQuery
plugin will probably see some added functionality.

Version 3 of the Google Geocoding Web service is also implemented to further
enable an unobtrusive javascript approach.

New: Events and Info Windows
You can now add info windows maps and markers and add event listeners.
Adding to the example below, in your views.py (right after "gmap =
maps.Map...") add:

    marker = maps.Marker(opts = {
        'map': gmap,
        'position': maps.LatLng(38, -97),
    })
    maps.event.addListener(marker, 'mouseover', 'myobj.markerOver')
    maps.event.addListener(marker, 'mouseout', 'myobj.markerOut')
    info = maps.InfoWindow({
        'content': 'Hello!',
        'disableAutoPan': True
    })
    info.open(gmap, marker)

Then, on your page:

<script type="text/javascript">
    window.myobj = {
        markerOver: function() { this.openInfoWindow(); },
        markerOut: function() { this.closeInfoWindow(); }
    };
</script>

That's it!


Example:

"""views.py"""
from django import forms
from django.shortcuts import render_to_response
from gmapi import maps
from gmapi.forms.widgets import GoogleMap


class MapForm(forms.Form):
    map = forms.Field(widget=GoogleMap(attrs={'width':510, 'height':510}))


def index(request):
    gmap = maps.Map(opts = {
        'center': maps.LatLng(38, -97),
        'mapTypeId': maps.MapTypeId.ROADMAP,
        'zoom': 3,
        'mapTypeControlOptions': {
             'style': maps.MapTypeControlStyle.DROPDOWN_MENU
        },
    })
    context = {'form': MapForm(initial={'map': gmap})}
    return render_to_response('index.html', context)


"""urls.py"""
from django.conf.urls.defaults import *


urlpatterns = patterns('',
    (r'', include('gmapi.urls.media')), # Use for debugging only.
    (r'^$', 'myapp.views.index'),
)


Then in your template put this somewhere:

{{ form.map }}
{{ form.media.js }}


This will result in html like:

<div class="gmap" style="position:relative;width:510px;height:510px;" id="id_map">
    <div class="{&quot;arg&quot;:[&quot;div&quot;,{&quot;mapTypeId&quot;:{&quot;val&quot;:&quot;MapTypeId.ROADMAP&quot;},&quot;mapTypeControlOptions&quot;:{&quot;style&quot;:{&quot;val&quot;:&quot;MapTypeControlStyle.DROPDOWN_MENU&quot;}},&quot;center&quot;:{&quot;arg&quot;:[38,-97],&quot;cls&quot;:&quot;LatLng&quot;},&quot;zoom&quot;:3}],&quot;cls&quot;:&quot;Map&quot;}" style="position:absolute;width:510px;height:510px"></div>
    <img style="position:absolute;z-index:1" width="510" height="510" alt="Google Map" src="http://maps.google.com/maps/api/staticmap?sensor=false&amp;center=38,-97&amp;maptype=roadmap&amp;zoom=3&amp;size=510x510" />
</div>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.js"></script>
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script type="text/javascript" src="gmapi/js/jquery.gmapi.js"></script>


Your map will be displayed as an image, and once/if javascript loads, it will be converted to a javascript map.
