Hi, I need to model four entities that share some attributes and behaviors and also have some unique attributes and behaviors. I need to be able to refer to them from other entities. And these entities are Singletons.
Ex: online marketplaces. They share common attributes like website, contact person, commission rates which are best stored in DB. But they differ in how you upload data to them - one of them supports FTP, other Dropbox - best modeled as implementation of an interface. There may be unique data associated with these behaviors. FTP credentials, Dropbox credentials. Also a product may need to refer to these marketplaces (Ex: where all is it going to be listed), so they need to be enumerable. I have considered class hierarchy + a central registry + on disk config files. But since this is a part of a larger Django project, implementing it like this kind of sticks out and integrating it with admin etc requires lot more work. What are the other options to model something like this? I feel like I'm missing something obvious. Thanks a lot!
