Can't import a module in Django project

Question

This is my django project folder:

mysite
├── mypage
│   ├── __init__.py
│   ├── __pycache__
│   │   ├── __init__.cpython-38.pyc
│   │   ├── admin.cpython-38.pyc
│   │   ├── apps.cpython-38.pyc
│   │   ├── models.cpython-38.pyc
│   │   ├── urls.cpython-38.pyc
│   │   └── views.cpython-38.pyc
│   ├── admin.py
│   ├── apps.py
│   ├── migrations
│   │   ├── __init__.py
│   │   └── __pycache__
│   │       └── __init__.cpython-38.pyc
│   ├── models.py
│   ├── tests.py
│   ├── urls.py
│   └── views.py
├── mysite
│   ├── __init__.py
│   ├── __pycache__
│   │   ├── __init__.cpython-38.pyc
│   │   ├── settings.cpython-38.pyc
│   │   ├── urls.cpython-38.pyc
│   │   └── wsgi.cpython-38.pyc
│   ├── asgi.py
│   ├── settings.py
│   ├── urls.py
│   └── wsgi.py
└── utils
    ├── __init__.py
    ├── __pycache__
    │   └── __init__.cpython-38.pyc
    └── util.py

This is the error message that I get when I run the server.

    Exception in thread django-main-thread:

    from mysite.utils.util import *
ModuleNotFoundError: No module named 'mysite.utils'

This is the view.py in mypage app folder:

from django.http import HttpResponse
from mysite.utils.util import *


def index(request):
    print_hi()
    return HttpResponse("Hello")

So the question is: How do I import util.py in view.py? It does work if I just move the utils inside mypage folder, but I'd like to know if it's possible to do it without moving utils folder.

Answer 1

You can use relative imports

like

from .utils.util import *
from ..utils.util import *
from ...utils.util import *

depending on your project structure
