Geonode installation notes

(may apply to other bundled django applications, where mod_wsgi is used to connect to django)

note this is out of date - should be revisited now Geonode has migrated to django 2.2

Use Case

an existing django application has been installed on unbuntu using apt-get

This is challenging as its not obvious where things are configured and how to propagate changes. Here are notes from going through this process - if there is a better way please document it here and throw these away!

Installing new apps

This is standard process - up to a point..

install django modules - into the same environment you app is installed - note that using the apt-get method means the app is globally installed, not into a virtualenv, and hence most of the django developer docs are no longer relevant

set up django-admin to use the default app :

  • this is tricky because with apt-get installation you do not get the containing django project directory with manage.py - at least I could not find if/where this was available in the default installation e.g. mkdir /usr/share/django-apps cd /usr/share/django-apps ln -s /usr/local/lib/python2.7/dist-packages/geonode . create a manage.py in /usr/share/django-apps edit so settings are geonode/settings ( note, you cannot run this inside geonode because of conflicts between imported module "geoserver" and local module! -

now we need to make the installed app know about the extensions: edit geonode/settings (eg local_settings.py) to include new packages in INSTALLED_APPS, and other settings required (RDFSTORE) edit geonode/urls.py

run python manage.py syncdb

NB this will load initial data

TODO

work out how signals to publish to remote RDFSTORE survive this installation process

to propagate configuration changes to running server:

touch /var/www/geonode/wsgi/geonode.wsgi

load some content for which RDF mappings exist test :

to get into debug mode on the server

one way to test stuff is: python manage.py shell

  • import all the things in the module you want to invoke so you can run methods and interact with object types: from django.shortcuts import render_to_response, redirect from rdf_io.models import ObjectMapping,Namespace,AttributeMapping, ObjectType, getattr_path from django.template import RequestContext from django.contrib.contenttypes.models import ContentType from django.conf import settings from string import Formatter import requests

  • set up debugger:

  • set up breakpoint

  • back to shell:

  • call function to debug

eg import pdb; pdb.set_trace() b rdf_io/views:217 c from rdf_io.views import do_sync_remote do_sync_remote('scheme')
