[Fixed]-Django 1.9 sqlflush ImproperlyConfigured error

You didn’t tell django-admin what project’s DB you want to flush. There are a few options:

• Use python manage.py sqlflush instead.
• Use django-admin sqlflush --settings=mysite.settings where mysite.settings is your settings module.
• Set the DJANGO_SETTINGS_MODULE environment variable in your operating system to mysite.settings where mysite.settings is your settings module. Then you can use django-admin sqlflush.
