Bug Report: Failed to Implement the Example on Django 4.0

[NoguchiShigeki]

• django_private_chat2 version: 1.0.1
• Django version: 4.0
• Python version: 3.9.7
• Operating System: Windows10 (Microsoft Windows [Version 10.0.19042.1415])

You may know this problem but I report this just in case.

I was trying to implement the example, I followed the instructions of "django_private_chat2/example/README.md5". In step5, I tried to apply migrations but an exception occurred.
Here's an error message:
ImportError: cannot import name 'url' from 'django.conf.urls'
I tried Django Version 3.2.10, it went well. All worked.

What I Did

Applied migrations on Django 4.0 (Failed)
Applied migrations on Django 3.2.10 (Success)

I'm very new to Programming and OSS Dev so I don't know this will help or not but I just report this.
This is what I was looking for! You guys doing a great job. Big thanks from the far east.

Hello, this might be the issue with the example because it wasn't updated to support Django 4.0 (as opposed to the package itself)
I hope to have the time to fix it soon

[delneg]

Please try the latest update from the repo, I've pushed some changes for django 4.0

[NoguchiShigeki]

Thanks for your quick response
