Congratulations on your excellent work. I try to install plugins, but I am always getting the same error.

 from django.conf.urls import patterns, url
ImportError: cannot import name 'patterns' from 'django.conf.urls' (C:\Users\ioann\AppData\Local\Programs\Python\Python38-32\lib\site-packages\django\conf\urls\__init__.py)

Can you please help?
I tried solutions found online, but with no luck.
Thank you

The literal cause of this error can be understood by looking at the contents of the file C:\Users\ioann\AppData\Local\Programs\Python\Python38-32\lib\site-packages\django\conf\urls\__init__.py you will likely discover that there is no variable or function called patterns in that file.

More generally, Django changed the naming and location of it's url code in a previous version.
It is highly likely that the code  

from django.conf.urls import patterns, url 

is incompatible with the version of Django you have installed.

Thank you very much. I have tried with different versions, which one should I have installed?

Thanks again

The version of Django that installs when you install Opal will work with that version of Opal.
A clean install as per the documentation will get you sensible versions.

It is possible that other code you try to run is incompatible with the latest version of either Django/Opal/ anything else. 

Without knowing where the code you pasted comes from, it's impossible to say what versions of things it expects.

Dear David,

Thank you very much for your help. I tried in a new venv but when I try to install a plugin, e.g. ons I am getting the same error.
I tried to change the url patterns to a list but then it says apps dont start yet.

Morning, 

What literal plugin are you attempting to install? Do you have a link to it?
Is the code you're working on that is causing the error online somewhere?

I tried with the opal-observations and the opal-dashboard. I installed them with pip, I added them on installed apps, but when I try to migrate I am getting these errors.
I tried to install the django booking plugin and I didn't have any problems.

Thank you again

It's generally better to try and do one thing at a time if it's going wrong.
I would try only installing the observations plugin. 
For instance, I would try installing it in a clean opal application created by startproject to check that the issue is not something in the application you're working on.

Thanks,
I tried to install obs on a fresh opal installation, but unfortunately I am getting the same error. I also tried in Linux and windows and the same error again.
Thank you

Hi Ioannis,
 I think it could be because some of the pypi repos for the plugins are out of date.

 If you install with 
pip install -e git+https://github.com/openhealthcare/opal-obser...@v0.5.0#egg=opal_observations

Do you still have the same issue? 

I'm going to review the pypi modules tomorrow. Those that do not support django 2.0 should declare it more explicitly.

 Thanks,

 Fred
