I’m using the latest tools provided by the latest Google App Engine (GAE) environment, i.e. Django 1.3 via

libraries:
- name: django
  version: "1.3"

as instructed by the GAE docs here.

Still, although I found a lot of links discussing how to send the blessed HTTP500 email using the powerful GAE-Django combo, all of them are outdated because they are either simply too old or use “additional” tools like AppEngineHelper or django-nonrel.

Back to my problem: I set up my settings.py to follow the Django docs instructions here, and since on GAE opening sockets is restricted I end up with this traceback:

ERROR    2012-03-21 23:11:15,855 base.py:209] Internal Server Error: /contact/
Traceback (most recent call last):
  File "/home/josvic/dev-tools/google_appengine/lib/django_1_3/django/core/handlers/base.py", line 111, in get_response
    response = callback(request, *callback_args, **callback_kwargs)
  File "/home/josvic/dev/qdsa/gae/apputil/decorators.py", line 14, in wrapper
    output = func(request, *args, **kw)

  File "/home/josvic/dev-tools/google_appengine/lib/django_1_3/django/core/mail/message.py", line 251, in send
    return self.get_connection(fail_silently).send_messages([self])
  File "/home/josvic/dev-tools/google_appengine/lib/django_1_3/django/core/mail/backends/smtp.py", line 79, in send_messages
    new_conn_created = self.open()
  File "/home/josvic/dev-tools/google_appengine/lib/django_1_3/django/core/mail/backends/smtp.py", line 42, in open
    local_hostname=DNS_NAME.get_fqdn())
  File "/home/josvic/dev-tools/google_appengine/lib/django_1_3/django/core/mail/utils.py", line 16, in get_fqdn
    self._fqdn = socket.getfqdn()
AttributeError: 'module' object has no attribute 'getfqdn'

So that is the problem. Do we have a standard way of circumventing this?

The only thing I can think of to bypass this problem is to resort to a custom 500error handler that uses GAE’s standard mail API.

    Two options I can think of are:

    1. Custom logging handler that uses GAE standard mail API, not too different from a 500 error handler, but you don’t have to rewrite the view: https://docs.djangoproject.com/en/dev/topics/logging/

    2. Replace the email backend. I’m not 100% certain this works, but I suspect it will. There’s already one in the Django-nonrel project (which incidentally, is still maintained)
      https://github.com/django-nonrel/djangoappengine
      look in mail.py
