I made a very first brute force test:
settings.py: (only DATABASES is set)
=======================================
import os
MYDIR = os.path.abspath(os.path.dirname(__file__))
DATABASES = {
'default' : {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(MYDIR, "tiny.db"),
'HOST': '',
'USER': '',
'PASSWORD': '',
'PORT': '',
}
}
myapp.py
==========
#!/usr/bin/env python
import os
# just set the env prior to importing a django module
os.environ['DJANGO_SETTINGS_MODULE'] = 'settings'
from django.db import models
print "yes this line is executed"
# this will fail :-(
class Mini(models.Model):
name = models.CharField(max_length=80)
###############################################
If running myapp.py I get following output:
yes this line is executed
Traceback (most recent call last):
File "./myapp.py", line 11, in <module>
class Mini(models.Model):
File
"/opt/my_python/lib/python2.6/site-packages/Django-1.3-py2.6.egg/django/db/models/base.py",
line 52, in __new__
kwargs = {"app_label": model_module.__name__.split('.')[-2]}
IndexError: list index out of range
(my_python)n1234@mypc:~/minidjango$
So I need at least a little more to make my script work.
