django-constance VS django-jazzmin

Can I use django-constance to change values in Django's settings files? Specifically I'd like to control the max file size upload setting DATA_UPLOAD_MAX_MEMORY_SIZE.

django-constance - Set global values using the admin interface.

Have you come across https://github.com/jazzband/django-constance? I think this might be able to help with some of your issues. It would at least allow you to save / change settings in your app globally that would work nicely with multiple workers. I typically use this library with Redis

There are also alternative admin themes (e.g. https://github.com/farridav/django-jazzmin) that you might like, which would replace the whole look and feel.

You could use Jazzmin > https://django-jazzmin.readthedocs.io/, or you could move the project to Wagtail. You get a lot out of the box with Wagtail but it could be overkill for your project.

You could add some style to the to the admin with this app https://github.com/farridav/django-jazzmin/blob/master/docs/index.md

Instead, if you are looking for an admin replacement you could give a look to django-jazzmin (I’m not the author), it is a recent package and even if there are many issues it seems to be maintained (for now).

This is pretty good. However, there was another one that's been around a bit longer that's also really nice. See here: https://github.com/farridav/django-jazzmin

Django Jazzmin

One of my Favorite ones is Django-Jazzmin which is a drop-in app with plenty of things you can easily customize, including a built-in UI customizer.

I've been using Django Jazzmin. It's got some nuances that I've had to work around but it looks a lot better than the plain admin interface. It's more mobile friendly too but, again, not perfect.
