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

from openwisp_utils.admin_theme.admin import admin, openwisp_admin

openwisp_admin()

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

urlpatterns += staticfiles_urlpatterns()

Settings

OPENWISP_CONNECTORS

type:	tuple
default:	( ('openwisp_controller.connection.connectors.ssh.Ssh', 'SSH'), )

Available connector classes. Connectors are python classes that specify ways in which OpenWISP can connect to devices in order to launch commands.

OPENWISP_UPDATE_STRATEGIES

type:	tuple
default:	( ('openwisp_controller.connection.connectors.openwrt.ssh.OpenWrt', 'OpenWRT SSH'), )

Available update strategies. An update strategy is a subclass of a connector class which defines an update_config method which is in charge of updating the configuratio of the device.

This operation is launched in a background worker when the configuration of a device is changed.

It’s possible to write custom update strategies and add them to this setting to make them available in OpenWISP.

OPENWISP_CONFIG_UPDATE_MAPPING

type:	dict
default:	{ 'netjsonconfig.OpenWrt': OPENWISP_UPDATE_STRATEGIES[0][0], }

A dictionary that maps configuration backends to update strategies in order to automatically determine the update strategy of a device connection if the update strategy field is left blank by the user.

Troubleshooting Steps

You may encounter some issues while installing GeoDjango.

Unable to load SpatiaLite library extension?

If you are getting below exception:

django.core.exceptions.ImproperlyConfigured: Unable to load the SpatiaLite library extension

then, You need to specify SPATIALITE_LIBRARY_PATH in your settings.py as explained in django documentation regarding how to install and configure spatialte.

Having Issues with other geospatial libraries?

Please refer troubleshooting issues related to geospatial libraries.
