How can I organize a relationship system in django? I need the ability to add / remove from friends, accept / reject an application for friends and the like, but I can’t imagine using what means to accomplish this. just learning

  • Yes, villain. But I am still interested in what fields this can be achieved in a separate class or within the user. In a word, I need architecture and a kick in the right direction - LiGhT_WoLF

  • Yes, something like that. There I was more interested in whether there are ready-made solutions. - LiGhT_WoLF

First, determine how much functionality you need in the relationship system, if the full functionality is like in VK (friends, requests, subscriptions), then you need three models of this type:

class Subscribe(models.Model): from_user = models.ForeignKey('auth.User') to_user = models.ForeignKey('auth.User', related_name="person_subscribers") class Friendship(models.Model): to_user = models.ForeignKey('auth.User', related_name="friends") from_user = models.ForeignKey('auth.User') class FriendshipRequest(models.Model): to_user = models.ForeignKey('auth.User', related_name="friendship_requests_to") from_user = models.ForeignKey('auth.User', related_name="friendship_requests_from") status = models.CharField(max_length=25, choices=REQUEST_STATUS, default=CREATED)

They are still managers with a bunch of methods, if without subscribers, then it is already easier.

  • So already interesting. Subscriptions just will not. Thanks for the advice - LiGhT_WoLF
