Django 3.x - cannot import name 'curry' from 'django.utils.functional'

[mohsen-hassani]

Describe the bug
ImportError: cannot import name 'curry' from 'django.utils.functional'

Reproduce behavior

• Create new virtualenv
• pip install django, pinax-blog
• Create new project with django-admin
• Add pinax.blog and pinax.images to INSTALLED_APPS
• Add pinax.blog.urls to urlpatterns
• replace: from django.utils.encoding import python_2_unicode_compatible
  with: from six import python_2_unicode_compatible due to this issue
• run python3 manage.py runserver or python3 manage.py migrate

It looks like this needs to be updated as part of dropping Python 2.x support. @mfonism has a branch in the works to do that, but I don't think curry has been updated yet. https://docs.djangoproject.com/en/3.0/releases/3.0/#removed-private-python-2-compatibility-apis

You may simply change the imports from django.utils.functional import curry to from funtools import partial as curry

@tiholic Thank you for that info! @mfonism has a PR in the works to update the test matrix for a new release. I will look into this. #129

@mohsenone, @tiholic... a new release has been tagged and published. Thank you! https://pypi.org/project/pinax-blog/

Managed to recreate this bug from a fresh 8.0.0 install.

File "/data/neil/.cache/pypoetry/virtualenvs/sc-blog-a7R5rCuA-py3.8/lib/python3.8/site-packages/pinax/blog/admin.py", line 3, in <module>
    from django.utils.functional import curry

Oops! I inadvertently missed this one 🙈!!

Just bit me in a side project a few minutes ago... But I see you have a PR for this, @neilmillard.

[KatherineMichel]

@mohsenone @neilmillard @tiholic @mfonism I am so sorry, everyone. I could have sworn I fixed this! Otherwise, would not have closed issue. Maybe I pushed to the wrong branch. I've merged @neilmillard's PR and published a new package. https://pypi.org/project/pinax-blog/8.0.1/

In case anyone comes across this, the import is typod here and should be functools not funtool.
