Django ORM on Standalone Applications

I followed this link to use Django's ORM on my stand alone application in python. manage.py sql 'application_name' and manage.py syncdb is working well and tables were created when I performed syncdb. The problem I am encountering is when I am running the actual script (for this case, it's dparser.py) that will handle DB transactions, I am encountering a "TypeError: relative imports require the 'package' argument". Below is the stacktrace:

Traceback (most recent call last):
  File "dparser.py", line 23, in <module>
    from dmodel.models import *
  File "/home/<user>/d/dapp/dmodel/models.py", line 1, in <module>
    from django.db import models
  File "/usr/local/lib/python2.7/site-packages/django/db/__init__.py", line 11, in <module>
    if DEFAULT_DB_ALIAS not in settings.DATABASES:
  File "/usr/local/lib/python2.7/site-packages/django/utils/functional.py", line 184, in inner
    self._setup()
  File "/usr/local/lib/python2.7/site-packages/django/conf/__init__.py", line 42, in _setup
    self._wrapped = Settings(settings_module)
  File "/usr/local/lib/python2.7/site-packages/django/conf/__init__.py", line 93, in __init__
    mod = importlib.import_module(self.SETTINGS_MODULE)
  File "/usr/local/lib/python2.7/site-packages/django/utils/importlib.py", line 28, in import_module
    raise TypeError("relative imports require the 'package' argument")
TypeError: relative imports require the 'package' argument

Below are the contents of my settings.py, models.py and dparser.py:

settings.py:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',   
        'NAME': 'd',
        'USER': 'root',
        'PASSWORD': '<password>',
        'HOST': 'localhost',
        'PORT': '3306',
    }
}
INSTALLED_APPS = ("dapp.dmodel",)

models.py:

from django.db import models
from django.db.models import Max


class Topics(models.Model):
     topic_id = models.AutoField(primary_key=True)
     topic = models.CharField(max_length=1000)

class Links(models.Model):
     link_id = models.AutoField(primary_key=True)
     topic = models.ForeignKey(Topics)
     link = models.CharField(max_length=1000)

def getLastId(tag):
     ...
     return lastid

dparser.py (partial):

from django.conf import settings
os.environ['DJANGO_SETTINGS_MODULE'] = ".settings.py"
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',   
        'NAME': 'd',
        'USER': 'root',
        'PASSWORD': '<password>',
        'HOST': 'localhost',
        'PORT': '3306',
    }
}
INSTALLED_APPS = ("dapp.dmodel",)

from dmodel.models import * # --> This is were the exception occurs

Hope somebody can help me out here. Thanks in advance!

Looking at the code of django.utils.importlib.py where the execption is raised you see that your settings file name is causing the problem:

if name.startswith('.'):
    if not package:
        raise TypeError("relative imports require the 'package' argument")

Don't use .settings.py as the name for your settings file, use something that does not start with a '.' and it will solve this particular error.

I'd guess you'd need to do

from dapp.dmodel.models import *

or set the PYTHONPATH or sys.path to include the dapp folder.
