First of all, I'm new to Django, so please be nice with me :D
I'm currently adapting .py files for Django 3 because the files I have are compatible for Django 2. So, some changes have been made for the new version and in a file, it's written :
@wraps(view_func, assigned=available_attrs(view_func))
With the import :
from django.utils.decorators import available_attrs
I searched for an adaptation of available_attrs, and I quickly found that it has been removed for the new version.
And when I launch the code, I have this :
ImportError : cannot import name 'available_attrs' from 'django.utils.decorators'
So I was wondering what should I write instead of available_attrs to make it work ?
PS : Sorry for my bad english
available_attrs() only ever existed to help bridge between Python 2 and Python 3. This is documented in the Django 3.0 release notes:
Removed private Python 2 compatibility APIs
While Python 2 support was removed in Django 2.0, some private APIs weren’t removed from Django so that third party apps could continue using them until the Python 2 end-of-life.
Since we expect apps to drop Python 2 compatibility when adding support for Django 3.0, we’re removing these APIs at this time.

django.utils.decorators.available_attrs()- This function returnsfunctools.WRAPPER_ASSIGNMENTS
If the @wraps() in your sample line is the standard functools.wraps() decorator, then you can just entirely remove assigned=available_attrs(...), because functools.WRAPPER_ASSIGNMENTS is the default value for assigned:
@wraps(view_func)
otherwise, just use functools.WRAPPER_ASSIGNMENTS directly.
