Quickstart

Setting Up Your Google API Key

Follow the instructions to get a key
Enable the following services under API Restrictions:

Installing and Configuration the Python Package

Install with pip install wagtailgmaps
Add wagtailgmaps to your settings.py INSTALLED_APPS section.

Add some configuration in your settings.py file:

# Mandatory
WAGTAIL_ADDRESS_MAP_CENTER = 'Wellington, New Zealand'  # It must be a properly formatted address
WAGTAIL_ADDRESS_MAP_KEY = 'xxx'

# Optional
WAGTAIL_ADDRESS_MAP_ZOOM = 8  # See https://developers.google.com/maps/documentation/javascript/tutorial#MapOptions for more information.
WAGTAIL_ADDRESS_MAP_LANGUAGE = 'ru'  # See https://developers.google.com/maps/faq#languagesupport for supported languages.

Use it:

# myapp/models.py
from django.db import models
from wagtail.wagtailcore.models import Page
from wagtailgmaps.edit_handlers import MapFieldPanel

class MapPage(Page):
    # Wagtailgmaps expects a `CharField` (or any other field that renders as a text input)
    formatted_address = models.CharField(max_length=255)
    latlng_address = models.CharField(max_length=255)

    # Use the `MapFieldPanel` just like you would use a `FieldPanel`
    content_panels = Page.content_panels + [
        MapFieldPanel('formatted_address'),
        MapFieldPanel('latlng_address', latlng=True),
    ]

# myapp/templates/myapp/map_page.html
<a href="http://maps.google.com/?q={{ self.formatted_address }}">Open map (Formatted Address)</a>
<a href="http://maps.google.com/?q={{ self.latlng_address }}">Open map (Lat/Long Address)</a>

Additional information

`MapFieldPanel` options

heading - A custom heading in the admin, defaults to "Location"
classname - Add extra css classes to the field
latlng - Field returns a LatLng instead of an address
centre - A custom override for this field
zoom - A custom override for this field

How the address option works under the hook

If using the address option, the field gets updated according to the Google Geocoding Service each time:

The map marker gets dragged and dropped into a location (dragend JS event).
Click happens somewhere in the map (click JS event).
Return key is pressed after editing the field (enterKey JS event for return key only).

Troubleshooting

When editing the model from the admin interface the affected field shows up with a map, like the screenshot above. If it doesn't, check your browser console to make sure that there is no error related to your API key.
