Django error: User matching query does not exist - django

Question

So I have these models in my Django project, and I am trying to get the user2 variable or the other user of my models
class ThreadManager(models.Manager):
def by_user(self, user):
qlookup = Q(first=user) | Q(second=user)
qlookup2 = Q(first=user) & Q(second=user)
qs = self.get_queryset().filter(qlookup).exclude(qlookup2).distinct()
return qs
def get_or_new(self, user, other_username): # get_or_create
username = user.username
if username == other_username:
return None
qlookup1 = Q(first__username=username) & Q(second__username=other_username)
qlookup2 = Q(first__username=other_username) & Q(second__username=username)
qs = self.get_queryset().filter(qlookup1 | qlookup2).distinct()
if qs.count() == 1:
return qs.first(), False
elif qs.count() > 1:
return qs.order_by('timestamp').first(), False
else:
Klass = user.__class__
user2 = Klass.objects.get(username=other_username)
if user != user2:
obj = self.model(first=user, second=user2)
obj.save()
return obj, True
return None, False
class Thread(models.Model):
first = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name='chat_thread_first')
second = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name='chat_thread_second')
updated = models.DateTimeField(auto_now=True)
timestamp = models.DateTimeField(auto_now_add=True)
objects = ThreadManager()
and my views
def Messages(request, *args, **kwargs):
Chats = Thread.objects.by_user(request.user)
other_username = kwargs.get("username")
other_user = Thread.objects.get_or_new(request.user, other_username)
context = {
'content': Chats,
'chatname': other_user
}
return render(request, "chat/messages.html", context)
But when I try to get the other user I get the title error. Does anybody know what is going on?
Thank you for the help!

Answer 1

By looking at your models, it seems that user2 variable is the second object, to get the second object you need to use only the content context you made, and loop for it in your template {% for chat in content %} {{ chat.second }} this will give you the second user that is not your user of all your objects
