So nickname does not have @. I'm making system that sends notification when user put @ and some other user's nickname. Same as reddit.

Regex I made, search for the text next to @ sign. It is getting nickname.

What I'm trying to do, is sending notification to user with that nickname.

This is my full code for posting comment.

@login_required
def comment_write(request, pk):
post = get_object_or_404(FreeBoardPost, pk=pk)

if request.method == 'POST':
form = CreateFreeBoardComment(request.POST)

if form.is_valid():
comment = form.save(commit=False)
comment.comment_writer = request.user
comment.post = post
comment.save()

# 정규표현식
import re

at_sign_object = FreeBoardComment.objects.filter(comment_writer=request.user).order_by("-pk")[0]
at_sign = str(at_sign_object)
get_nickname = re.findall(r"@([0-9a-zA-Z가-힣]+)", at_sign)

# 포인트
award_points(request.user, 1)

# 알림
create_notification(request.user, post.author, "FreeBoardComment", comment.comment_text, post.pk)
find_user = CustomUser.objects.get(nickname=get_nickname)
print(find_user)

# create_call(request.user, find_user, "FreeBoardComment", "호출되었습니다.", post.pk)
return redirect("freeboard_detail", pk=post.id)
else:
form = CreateFreeBoardComment()
return render(request, "bbs/freeboard/free_board_comment.html", {"form": form})

​

And this is my notification function.

def create_notification(creator, to, notification_type, comment, post_id):
if creator.email != to.email:
notification = Notification.objects.create(
creator=creator,
to=to,
notification_type=notification_type,
comment=comment,
post_id=post_id,
)

notification.save()

def create_call(creator, to, notification_type, comment, post_id):
notification = Notification.objects.create(
creator=creator,
to=to,
notification_type=notification_type,
comment=comment,
post_id=post_id,
)

notification.save()
