1. Django Tutorial(Airbnb) - Meta Class

🌈 Meta Class

🔥 abstract

🔥 verbose_name & verbose_name_plural

🔥 ordering

1. abstract

class AbstractItem(core_models.TimeStampedModel): # 👈 TimeStampedModel 상속 받음
    """AbstractItem Object Definition"""
    name = models.CharField(max_length=80)
    class Meta:
        abstract = True # 👈 Abstract Model로 사용
    def __str__(self):
        return self.name
class RoomType(AbstractItem): # 👈 AbstractItem 상속 받음
    """Room Type Model Definition"""
    pass
class Amenity(AbstractItem): # 👈 AbstractItem 상속 받음
    """Amenity Model Definition"""
    pass
class Facility(AbstractItem): # 👈 AbstractItem 상속 받음
    """Facility Model Definition"""
    pass
class HouseRule(AbstractItem): # 👈 AbstractItem 상속 받음
    """HouseRule Model Definition"""
    pass 

2. verbose_name & verbose_name_plural

Admin Panelを見ると、Djangoにはすべてのモデル名に「s」が付けられているのが見えます.Djangoは復讐で表現します

class RoomType(AbstractItem):
    """Room Type Model Definition"""
    class Meta:
        verbose_name = "Room Type" # 👈 Room Types로 나타남
class Amenity(AbstractItem):
    """Amenity Model Definition"""
    class Meta:
        verbose_name_plural = "Amenities" # 👈 Amenities로 나타남
class Facility(AbstractItem):
    """Facility Model Definition"""
    class Meta:
        verbose_name_plural = "Facilities" # 👈 Facilities로 나타남
class HouseRule(AbstractItem):
    """HouseRule Model Definition"""
    class Meta:
        verbose_name = "House Rule" # 👈 House Rules로 나타남

3. ordering

class RoomType(AbstractItem):
    """Room Type Model Definition"""
    class Meta:
        verbose_name = "Room Type"
        ordering = [created] # 👈 생성시간 기준으로 정렬(부모 Model에 created 필드가 존재)
class Amenity(AbstractItem):
    """Amenity Model Definition"""
    class Meta:
        verbose_name_plural = "Amenities"
        ordering = [name] # 👈 알파벳 기준으로 정렬(부모 Model에 name 필드가 존재)
