django-friendship

This application enables you to create and manage follows, blocks and bi-directional friendships between users. It features:

Friendship request objects that can be accepted, rejected, canceled, or marked as viewed.
Hooks to easily list all friend requests sent or received by a given user, filtered by the status of the request.
A blocklist for each user of users they've blocked.
Tags to include information about friendships, blocks and follows in your templates.
Integration with AUTH_USER_MODEL.
Validation to prevent common mistakes.
Faster server response time through caching

Requirements

Django 1.11+ since v1.7.0 (latest release supporting Django 1.10 is v1.6.0)

Installation

pip install django-friendship
add "friendship" to INSTALLED_APPS and run python manage.py migrate.
Use the friendship manager in your own views, or wire up the URLconf to include the builtin views:

urlpatterns = [
    ...
    path('friendship/', include('friendship.urls'))
    ...
]

Note: If you are migrating from django-friendship v1.6.x, you'll need to rollback your migrations and fake migration 0002

$ ./manage.py migrate friendship 0001
$ ./manage.py migrate friendship 0002 --fake

If you're migrating from v1.7.x, you'll likely have to fake 0003 as well:

$ ./manage.py migrate friendship 0003 --fake

Usage

django-friendship provides a free API that gives you several ways to create and manage friendship requests or follows in your views. Add the following at the top of your views.py:

from django.contrib.auth.models import User
from friendship.models import Friend, Follow, Block

Getting Data about Friendships

List all of a user's friends: Friend.objects.friends(request.user)
List all unread friendship requests: Friend.objects.unread_requests(user=request.user)
List all unrejected friendship requests: Friend.objects.unrejected_requests(user=request.user)
Count of all unrejected friendship requests: Friend.objects.unrejected_request_count(user=request.user)
List all rejected friendship requests: Friend.objects.rejected_requests(user=request.user)
Count of all rejected friendship requests: Friend.objects.rejected_request_count(user=request.user)
List of all sent friendship requests: Friend.objects.sent_requests(user=request.user)
Test if two users are friends: Friend.objects.are_friends(request.user, other_user) == True

Getting Data about Follows

List of a user's followers: Follow.objects.followers(request.user)
List of who a user is following: Follow.objects.following(request.user)

Getting Data about Blocks

List of a user's blockers: Block.objects.blockers(request.user)
List of who a user is blocking: Block.objects.blocking(request.user)
Test if a user is blocked: Block.objects.is_blocked(request.user, other_user) == True

Managing Friendships and Follows

Create a friendship request:

other_user = User.objects.get(pk=1)
Friend.objects.add_friend(
    request.user,                               # The sender
    other_user,                                 # The recipient
    message='Hi! I would like to add you')      # This message is optional

Let the user who received the request respond:

from friendship.models import FriendshipRequest

friend_request = FriendshipRequest.objects.get(to_user=1)
friend_request.accept()
# or friend_request.reject()

To remove the friendship relationship between `request.user` and `other_user`, do the following:

Friend.objects.remove_friend(request.user, other_user)

Make request.user a follower of other_user:

Follow.objects.add_follower(request.user, other_user)

Make request.user block other_user:

Block.objects.add_block(request.user, other_user)

Make request.user unblock other_user:

Block.objects.remove_block(request.user, other_user)

Templates

You can use django-friendship tags in your templates. First enter:

{% load friendshiptags %}

Then use any of the following:

{% friends request.user %}
{% followers request.user %}
{% following request.user %}
{% friend_requests request.user %}
{% blockers request.user %}
{% blocking request.user %}
