Global settings

To use the global settings of wagtail-global-settings you need to define a model, which inherits from AbstractGlobalSettingsCollection:

from django.db import models
from wagtail.wagtailadmin.edit_handlers import FieldPanel
from wagtail_global_settings.models import AbstractGlobalSettingsCollection

class GlobalSettings(AbstractGlobalSettingsCollection):
    facebook_app_id = models.CharField(max_length=256)
    google_app_id = models.CharField(max_length=256)
    analytics_id = models.CharField(max_length=256)

    panels = [
        FieldPanel('facebook_app_id'),
        FieldPanel('google_app_id'),
        FieldPanel('analytics_id'),
    ]

    class Meta:
        verbose_name = "Global settings"

For the frontend you have three options:

• use the context processor:

Add 'wagtail_global_settings.context_processors.global_settings' to your TEMPLATE_CONTEXT_PROCESSORS and then use the settings in your template: {{ global_settings.home.GlobalSettings.facebook_app_id }}

• use the template tags:

Add {% load global_settings_tags %} at the beginning of your template and then use the tags in your template: {% global_settings 'home' 'GlobalSettings' 'facebook_app_id' %} or {% get_global_settings 'home' 'GlobalSettings' 'facebook_app_id' as facebook_app_id %} {{ facebook_app_id }}. It’s possible to skip the field name, in which case you’ll get the singleton model instance: {% get_global_settings 'home' 'GlobalSettings' as global_settings %} {{ global_settings.facebook_app_id }}

• use the template tags provided by django-solo:

Add {% load solo_tags %} at the beginning of your template and then use the tag in your template: {% get_solo 'home.GlobalSettings' as global_settings %} {{ global_settings.facebook_app_id }}

Site specific settings

To use the site specific settings of wagtail-global-settings you need to define a model, which inherits from AbstractSiteSettingsCollection:

from django.db import models
from wagtail.wagtailadmin.edit_handlers import FieldPanel
from wagtail_global_settings.models import AbstractSiteSettingsCollection

class GlobalSettings(AbstractSiteSettingsCollection):
    facebook_app_id = models.CharField(max_length=256)
    google_app_id = models.CharField(max_length=256)
    analytics_id = models.CharField(max_length=256)

    panels = [
        FieldPanel('facebook_app_id'),
        FieldPanel('google_app_id'),
        FieldPanel('analytics_id'),
    ]

    class Meta:
        verbose_name = "Global site settings"

The usage is the same as with AbstractGlobalSettingsCollection, except:

• make sure 'wagtail.wagtailcore.middleware.SiteMiddleware' is in MIDDLEWARE_CLASSES

• use 'wagtail_global_settings.context_processors.site_settings' instead of 'wagtail_global_settings.context_processors.global_settings' and put it after 'django.template.context_processors.request' in TEMPLATE_CONTEXT_PROCESSORS

• use {% load site_settings_tags %} instead of {% load global_settings_tags %}

• use {% site_settings %} instead of {% global_settings %} in the template

• use {% get_site_settings %} instead of {% get_global_settings %} in the template

• django-solo cannot be used with site specific settings

The template tags for site specific settings allow passing and optional site argument: {% site_settings 'home' 'GlobalSettings' 'facebook_app_id' the_site %}. If this argument is missing the settings for the current site will be returned.

Usage in views

For AbstractGlobalSettingsCollection:

from home.models import GlobalSettings

def view_func_global(request):
    global_settings = GlobalSettings.get_solo()
    return render(request, 'home/the_template.html', {
        'facebook_app_id': global_settings.facebook_app_id,
    })

For AbstractSiteSettingsCollection:

from home.models import GlobalSettings

def view_func_global(request):
    site_settings = GlobalSettings.objects.for_site(request.site)
    return render(request, 'home/the_template.html', {
        'facebook_app_id': site_settings.facebook_app_id,
    })

General

The template tags may be used in two ways: {% site_settings 'home' 'GlobalSettings' 'facebook_app_id' %} and {% site_settings 'home.GlobalSettings.facebook_app_id' %}.
