Use the Django ORM in a standalone script (again)

Question

I'm trying to use the Django ORM in some standalone screen scraping scripts. I know this question has been asked before, but I'm unable to figure out a good solution for my particular problem.

I have a Django project with defined models. What I would like to do is use these models and the ORM in my scraping script. My directory structure is something like this:

project
    scrape
        #scraping scripts
        ...
        test.py
    web
        django_project
            settings.py
            ...
            #Django files

I tried doing the following in project/scrape/test.py:

print os.path.join(os.path.abspath('..'), 'web', 'django_project')
sys.path.append(os.path.join(os.path.abspath('..'), 'web', 'django_project'))
print sys.path
print "-------"
os.environ['DJANGO_SETTINGS_MODULE'] = 'django_project.settings'
#print os.environ
from django_project.myapp.models import MyModel
print MyModel.objects.count()

However, I get an ImportError when I try to run test.py:

Traceback (most recent call last):
  File "test.py", line 12, in <module>
    from django_project.myapp.models import MyModel
ImportError: No module named django_project.myapp.models

One solution I found around this problem is to create a symbolic link to ../web/govcheck in the scrape folder:

:scrape rmanocha$ ln -s ../web/govcheck ./govcheck

With this, I can then run test.py just fine. However, this seems like a hack, and more importantly, is not very portable (I will have to create this symbolic link everywhere I run this code).

So, I was wondering if anyone has any better solutions for my problem?

Answer 1

Are you sure it shouldn't be:

sys.path.append(os.path.join(os.path.abspath('..'), 'web'))

Also, make sure there's an __init__.py file (empty is fine) in project/web/django_project.

P.S. I'd recommend feeding os.path.join's output to os.path.abspath instead of the other way.
