Setup (integrate in an existing django project)

INSTALLED_APPS and EXTENDED_APPS (an internal openwisp2 setting) in settings.py should look like the following (ordering is important):

INSTALLED_APPS = [
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.gis',
    # openwisp2 admin theme
    # (must be loaded here)
    'openwisp_utils.admin_theme',
    # all-auth
    'django.contrib.sites',
    'allauth',
    'allauth.account',
    'allauth.socialaccount',
    'django_extensions',
    # openwisp2 module
    'openwisp_controller.config',
    'openwisp_controller.pki',
    'openwisp_controller.geo',
    'openwisp_controller.connection',
    'openwisp_users',
    # admin
    'django.contrib.admin',
    # other dependencies
    'sortedm2m',
    'reversion',
    'leaflet',
    # rest framework
    'rest_framework',
    'rest_framework_gis',
    # channels
    'channels',
]

EXTENDED_APPS = ('django_netjsonconfig', 'django_x509', 'django_loci',)

Ensure you are using one of the available geodjango backends, eg:

DATABASES = {
    'default': {
        'ENGINE': 'django.contrib.gis.db.backends.spatialite',
        'NAME': 'openwisp-controller.db',
    }
}

Add openwisp_utils.staticfiles.DependencyFinder to STATICFILES_FINDERS in your settings.py:

STATICFILES_FINDERS = [
    'django.contrib.staticfiles.finders.FileSystemFinder',
    'django.contrib.staticfiles.finders.AppDirectoriesFinder',
    'openwisp_utils.staticfiles.DependencyFinder',
]

Add openwisp_utils.loaders.DependencyLoader to template loaders and openwisp_utils.admin_theme.context_processor.menu_items to context processors in the TEMPLATES setting of settings.py:

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'OPTIONS': {
            'loaders': [
                'django.template.loaders.filesystem.Loader',
                'django.template.loaders.app_directories.Loader',
                'openwisp_utils.loaders.DependencyLoader',
            ],
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
                'openwisp_utils.admin_theme.context_processor.menu_items'
            ],
        },
    }
]

Add the following settings to settings.py:

FORM_RENDERER = 'django.forms.renderers.TemplatesSetting'

ASGI_APPLICATION = 'openwisp_controller.geo.channels.routing.channel_routing'
CHANNEL_LAYERS = {
    'default': {
        'BACKEND': 'channels.layers.InMemoryChannelLayer'
    },
}

LOGIN_REDIRECT_URL = 'admin:index'
ACCOUNT_LOGOUT_REDIRECT_URL = LOGIN_REDIRECT_URL

urls.py:

from django.conf.urls import include, url
from django.contrib import admin
from django.contrib.staticfiles.urls import staticfiles_urlpatterns

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'', include('openwisp_controller.urls')),
]

urlpatterns += staticfiles_urlpatterns()

Signals

is_working_changed

Path: openwisp_controller.connection.signals.is_working_changed

Arguments:

• instance: instance of DeviceConnection

• is_working: value of DeviceConnection.is_working

• old_is_working: previous value of DeviceConnection.is_working, either None (for new connections), True or False

• failure_reason: error message explaining reason for failure in establishing connection

This signal is emitted every time DeviceConnection.is_working changes.

It is not triggered when the device is created for the first time.
