Sniffer Can't Find DJANGO_SETTINGS_MODULE

I'm trying to automate the test rerun after a change while developing. After searching around a little sniffer seemed fine. But if I run it my tests fail with this error: ERROR: F

Solution 1:

Something like the following as your scent.py should work:

from subprocess import call
from sniffer.api import runnable

@runnable
def execute_tests(*args):
    fn = [ 'python', 'manage.py', 'test' ]
    fn += args[1:]
    return call(fn) == 0

Which you can then call as sniffer -x appName.

Solution 2:

You can get sniffer to read your settings by creating a scent.py file in the same directory as manage.py.

Here's what mine looks like:

import os
os.environ["DJANGO_SETTINGS_MODULE"] = 'myapp.settings'

Which will get you as far as sniffer reading your settings, but then you'll run into other problems — basically, sniffer just runs your tests using nose, which isn't the same thing that the manage.py test does when django-nose is installed.

Anybody know what else needs to be in scent.py for snigger to with with Django?

Solution 3:

Trying to guess where the problem may reside: it seems you need to explicitly set the position of your settings.py file.

if you're running your test from a subprocess' call you can use the following command:

call(["django-admin.py", "test --settings=your_project.settings"])

otherwise you can set environment variables with the following command:

import os
os.environ['DJANGO_SETTINGS_MODULE'] = 'your_project.settings'

(change your_project with the name of your django project)

if you're running a command like "./manage.py tests" you can add the former lines at the beginning of manage.py (there are other ways but I need to see the code to provide a more precise solution)
