I've a project in django 3.2 and I've updated (pip install -r requirements.txt) to version 4.0 (new release) and I've currently the below error when I run the server in a virtual environment. I use DRF.
Can't import => from rest_framework import routers in urls.py
from django.conf.urls import url ImportError: cannot import name 'url' from 'django.conf.urls'

The most basic technique to name Django urls is to add the name attribute to url definitions in urls.py . Listing 2-16 shows how to name a project's home page, as well as how to reference this url from a view method or template.
The path function is contained with the django. urls module within the Django project code base. path is used for routing URLs to the appropriate view functions within a Django application using the URL dispatcher.
A function that takes a prefix, and an arbitrary number of URL patterns, and returns a list of URL patterns in the format Django needs. The first argument to patterns() is a string prefix .
django.conf.urls.url () was deprecated in Django 3.0, and is removed in Django 4.0+. The easiest fix is to replace url () with re_path (). re_path uses regexes like url, so you only have to update the import and replace url with re_path.
The easiest fix is to replace url () with re_path (). re_path uses regexes like url, so you only have to update the import and replace url with re_path. from django.urls import include, re_path from myapp.views import home urlpatterns = [ re_path (r'^$', home, name='home'), re_path (r'^myapp/', include ('myapp.urls'), ]
This is very important, not least because the latest PyCharm tutorial at Jetbrains still uses django.conf.urls. Especially for newer folks, it's always disconcerting to have code copied from a tutorial breaking on you. @user.dz the Django 4.0 template doesn't use url.
A callable, or a string representing the full Python import path to the view that should be called if the user doesn’t have the permissions required to access a resource. By default, this is django.views.defaults.permission_denied ().
As per the Django docs here:
url(regex, view, kwargs=None, name=None)¶ This function is an alias to django.urls.re_path().
Deprecated since version 3.1: Alias of django.urls.re_path() for backwards compatibility.
django.conf.urls.url() was deprecated since Django 3.1, and as per the release notes here, is removed in Django 4.0+.
You can resolve the issue using path or re_path.
