1. Django Tutorial(Airbnb) - Abstract Model

🌈 Abstract Model

🔥 抽象モデルとは?

🔥 抽象モデル継承の取得

🔥 Django Countryライブラリ

1.抽象モデルとは？

1) core/models.py

from django.db import models
# Create your models here.
class TimeStampedModel(models.Model): # 👈 다른 모델에서 사용되어질 Abstract Model입니다:)
    """Time Stamped Definition"""
    created = models.DateField(auto_now_add=True) # 👈 다른 모델에서 공통적으로 사용할 필드
    updated = models.DateField(auto_now=True) # 👈 다른 모델에서 공통적으로 사용할 필드
    class Meta: 
        abstract = True # 👈 Abstract Model로 사용하기 위해서는 abstract=True를 지정해줘야해요!

2.抽象モデル継承の取得

1) rooms/models.py

from django.db import models
from core import models as core_models
# Create your models here.
class Room(core_models.TimeStampedModel): # 👈 TimeStampedModel의 필드를 상속 받아 사용
    """Room Model Definifion"""
    pass

3.Django Countryライブラリ

1)Django国とは?

2) settings.py

# Application definition
DJANGO_APPS = [
    "django.contrib.admin",
    "django.contrib.auth",
    "django.contrib.contenttypes",
    "django.contrib.sessions",
    "django.contrib.messages",
    "django.contrib.staticfiles",
]
PROJECT_APPS = [
    "users.apps.UsersConfig",
    "rooms.apps.RoomsConfig",
    "reviews.apps.ReviewsConfig",
    "reservations.apps.ReservationsConfig",
    "lists.apps.ListsConfig",
    "core.apps.CoreConfig",
    "conversations.apps.ConversationsConfig",
]
THIRD_PARTY_APPS = [
    "django_countries", # 👈 Django Country App 등록
]
INSTALLED_APPS = DJANGO_APPS + PROJECT_APPS + THIRD_PARTY_APPS

3) rooms/models.py

from django.db import models
from django_countries.fields import CountryField # 👈 Django Country 가져오기
from core import models as core_models
# Create your models here.
class Room(core_models.TimeStampedModel):
    """Room Model Definifion"""
    name = models.CharField(max_length=140)
    description = models.TextField()
    country = CountryField()  # 👈 끝.
