Problem importing ModelResource from tastypie.resources

Question

Good day, I'm currently on the middle of a practice project for django and can't seem to find a solution to a problem when creating an api with tastypie. I'm currently in the middle of learning so any help would be appreciated. I'm using django 4.0 and tastypie 2.8.2.

Here's the code which seems to be the problem:

from django.db import models
from tastypie.resources import ModelResource

Here's the full error I'm getting when attempting to execute python3 manage.py runserver on my venv:

After a bit of searching I found that some people managed to solve it by substituting "url" to "re_path" on the import however this doesn't seem to be working for me.

Here's how my resources.py file looks until the import error:

from __future__ import unicode_literals

from copy import copy, deepcopy
from datetime import datetime
import logging
import sys
from time import mktime
import traceback
import warnings
from wsgiref.handlers import format_date_time

from django.conf import settings
from django.conf.urls import url

The solution was apparently changing that last line to from django.conf.urls import re_path but the error I'm getting now is "from django.conf.urls import url ImportError: cannot import name 're_path' from 'django.conf.urls'". The problem seems to begin when I import ModelResource from the tastypie/resources directory so I checked the resources file for the ModelResource class and found it empty:

class ModelResource(six.with_metaclass(ModelDeclarativeMetaclass, BaseModelResource)):
    pass

I'm not sure if that might have something to do though as this is how it was from installation. All packages were installed within the venv.

Again, I'm currently in the middle of learning so any assistance is deeply appreciated.
