Using singleton-admin will allow users to only add one instance of a model via the django admin site. Once created, the instance can be updated and deleted, but additional instances cannot be created.
This is useful if you’d like to store a page content in the database for example.
I found myself using this package (https://github.com/tttallis/django-singletons) a lot, but some of the code has now been depreciated through newer releases of Django.
I originally had the intention of forking the package and making the fixes, but in the end I ended up re-writing from scratch. The end goal is the same, but with a different approach.
I appreciate that there are probably plenty of packages out there that offer similar functionality, but as I’ve put this together and have used in my own projects, I thought I’d get it out there.
Add “singleton_admin” to your INSTALLED_APPS:
INSTALLED_APPS = [ ... 'singleton_admin', ]
In your apps admin.py file to make your model a singleton-admin you can either do:
from singleton_admin.admin import SingletonAdmin admin.site.register(your_model, SingletonAdmin)
Or if you’d like to add your own admin class:
from singleton_admin.admin import SingletonAdmin class your_model_admin(SingletonAdmin): ... admin.site.register(your_model, your_model_admin)
TODO: Figure out how to actually get changelog content.
