separate python script cannot find self-defined module inside Django

Question

This is my Django app folder structure

|-----tt
|      |--settings.py
|
|-----warehouse
|       |--models.py
|       |--__init__.py
|
|-----dashboard
|       |--email_excel_reports.py
|

Inside my email_excel_reports.py

# for ORM query
from warehouse.models import EntryFormLineItem
from django.db.models import Sum
from django.db.models.functions import Coalesce
from django.utils import timezone


line_items = EntryFormLineItem.objects.filter(approved_by__isnull=False, ...

I got this error when I run python email_excel_reports.py inside dashboard

Traceback (most recent call last):
  File "/vagrant/dashboard/email_excel_reports.py", line 11, in <module>
    from warehouse.models import EntryFormLineItem
ImportError: No module named 'warehouse'

Bear in mind that when I run the python email_excel_reports.py I was running gunicorn with nginx, so the django app is running successfully.

The __init__.py inside warehouse

default_app_config = 'warehouse.apps.WarehouseConfig'

When I run python manage.py shell and then type the same lines of code, there was no problem running the code.

How do I get over the error?

RE-OPEN -- WHY?

Simply because the fix was to have python manage.py shell < placed in front of the python script file and this fix was not available in the supposedly duplicated question's answers.

is there a `__init__.py` file in your `warehouse` directory? — shady, Dec 17 '16 at 06:43
You need to set up django environment, when you want to run this script in command line. — shady, Dec 17 '16 at 06:52
I am already running gunicorn and nginx when I run the python script. And I read the question about using django for CLI tool. So I need to add `# Setup django import django django.setup()` inside manage.py? — Kim Stacks, Dec 17 '16 at 07:06

Because of the need to include the django modules, the better way to run this is

python manage.py shell < dashboard/email_excel_reports.py

I just solved this problem by putting the standalone Python file into the same directory as manage.py. (Since it's in the project root directory, all the modules are available beneath it).
