django-taggit VS django-allauth

django-taggit - for tags

Well taggit is basically M2M already. It even has a 'similar_objects' method. The problem is, especially for a list view, that the query is ran for each blog post item and you can't prefetch it. Which certainly slows everything down.

django-taggit works exactly the way you want

If you don't want to use Pegasus or another paid product (presumably because of the cost), the packages I'd reach for are django-allauth for login/user stuff and dj-stripe for the Stripe integration. As for teams, there wasn't a library I was happy with so I rolled my own for Pegasus, but some people like django-tenants. It's too heavyweight for my taste as it requires a more complex dev/test/infrastructure setup with Postgres schemas, as opposed to having a single-database and handling multitenancy in the application layer. But there are pros and cons to both approaches.

django-allauth - authorisation with email and social media accounts

Complete user authentication (Log-in/Log-out, ...) via Django Allauth

I've been screwing around with https://github.com/pennersr/django-allauth/. I got it up and running; was able to get Discord and Twich oauth2 working on it without much issue, Steam's OpenID implementation is really giving me a hard time though.

Usually when people talk about oauth with django, they mean letting users access a django app using oauth and django-allauth is often a good choice for that, but if you're accessing an API that doesn't sound like what you're after.

When I started web development with Django. I thoroughly didn't know about the django-allauth package. I had knowledge of MVC and some core parts of Django. During college projects I had been working on a demo project and done user authentication and all manually. That time one of my seniors advised me to use django-allauth. I did some research and configured django-allauth with my project within a couple of minutes. For me it was an invigorating thing.

Although the answer given below solved my problem, I just want to share that I ended up using django-allauth instead of social-auth. And the latest version of django-allauth appears to be the best Django authentication app.
