Disable django-haystack During Testing

I use django-haystack and elasticsearch for the search engine in our apps. But I don’t want my model that registered to haystack do indexing during the testing. I avoid haystack indexing by adding these following lines of code below in my settings.py.

import sys

TESTING = 'test' in sys.argv
    HAYSTACK_SIGNAL_PROCESSOR = 'haystack.signals.BaseSignalProcessor'
    HAYSTACK_CONNECTIONS['default'] = {
        'ENGINE': 'haystack.backends.simple_backend.SimpleEngine',

Fixing Git: refusing to merge unrelated histories

I have a new project and I add git repo later on after the project finished.
After setup remote repo to my project, I got this kind of error when pulling data from the repository.

fatal: refusing to merge unrelated histories

The problem fixed by adding this argument to git command “–allow-unrelated-histories”.

$ git pull upstream master --allow-unrelated-histories
