Django:在用户连接时添加随机ManyToMany关系

from django.db import models

class User(models.Model):
    name = models.CharField(max_length=100)
    connections = models.ManyToManyField('Connection')

class Connection(models.Model):
    name = models.CharField(max_length=100)

from django.shortcuts import get_object_or_404

def create_connection(request, user_id, connection_id):
    user = get_object_or_404(User, id=user_id)
    connection = get_object_or_404(Connection, id=connection_id)
    user.connections.add(connection)

def get_connections(request, user_id):
    user = get_object_or_404(User, id=user_id)
    connections = user.connections.all()
    # 处理连接数据
    return connections

def delete_connection(request, user_id, connection_id):
    user = get_object_or_404(User, id=user_id)
    connection = get_object_or_404(Connection, id=connection_id)
    user.connections.remove(connection)
