[Python] Django의 Paginator로 쉽게 페이징 해주자

# views.py

from django.core.paginator import Paginator
from rooms import models as room_models

def all_rooms(requests):

    # page라는 query받고, query가 없을 경우 1
    page = requests.GET.get("page", 1)

    """Paginator 써서 구현"""
    # 사용할 contents
    room_list = room_models.Room.objects.all()
    # paginator 설정 (contents_list, 10 == 페이지당 content 갯수)
    paginator = Paginator(room_list, 10)
    # n페이지(10개)에 해당하는 contents 가지고 오기
    rooms = paginator.get_page(page)
    
    return render(
        requests,
        "rooms/home.html",
        {
            "rooms": rooms,
        },
