Quickstart

Setting Up Your Google API Key

1. Follow the instructions to get a key
2. Enable the following services under API Restrictions:
   • Geocoding API
   • Maps Static API
   • Maps JavaScript API
   • Maps Embed API

Installing and Configuration the Python Package

1. Install with pip install wagtailgmaps

2. Add wagtailgmaps to your settings.py INSTALLED_APPS section.

3. 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.

4. 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.
