Question

Im not sure how to put this title.
But what I need is a simple model that I can just update everytime. Lets say I have a Settings model ,and these settings I just want to update or change every now and again. So there is no need to add another object to that model.

Is there suck a field or type of admin-model that I can use?

I could otherwise just keep updating the same object, but I do not want the user to be able to just “Add Setting”.

Answer 1

in admin you can specify various permissions. to remove the “add” functionality:

class MyModelAdmin(admin.ModelAdmin):
    def has_add_permission(self, request): return False

make sure you create your first and only settings object when you deploy the application.
