05. 다른 앱 설정

1) reviews 앱

숙소에 대한 후기 기능을 추가할 것이다.

1. Settings.py에 앱을 추가해준다.
   

PROJECT_APPS = ["reviews.apps.ReviewsConfig",]

2. models.py를 작성한다.
   review - models.py

from core import models as models_core

class Review(models_core.TimeStampedModel):

    """Review Model Definition"""
    
    preview = models.TextField()
    cleanliness = models.IntegerField()
    accuracy = models.IntegerField()
    communication = models.IntegerField()
    location = models.IntegerField()
    check_in = models.IntegerField()
    value = models.IntegerField()
    user = models.ForeignKey("users.User", on_delete=models.CASCADE)
    room = models.ForeignKey("rooms.Room", on_delete=models.CASCADE)

3. admin.py를 설정한다
   reviews - admin.py

from django.contrib import admin
from . import models

@admin.register(models.Review)
class ReviewAdmin(admin.ModelAdmin):

    """Review Admin Definition"""

    pass

4. migration
   
   admin 패널
   

5. __str__ 메소드 추가
   Review가 단순히 Object 1로 뜬다.
   

review - models.py - Review

def __str__(self):
    self.review

ForeignKey에 해당하는 필드를 입력하면 이를 타고 들어가 해당 필드와 연과된 다른 정보도 불러올 수 있다.

return self.room.country

타고 들어간 필드에 또 다른 ForeignKey가 있다면 또 타고 들어갈 수 있다.

최종은 아래와 같이 한다.

return f"{self.review} - {self.room}"

2) reservations 앱

1. settings.py에 등록

> PROJECT_APPS = ["reservations.apps.ReservationsConfig",]

2. models.py 수정

from django.db import models

class Reservation(models_core.TimeStampedModel):
    """Reservation Model Definition"""

    STATUS_PENDING = "pending"
    STATUS_CONFIRMED = "confirmed"
    STATUS_CANCELED = "canceled"

    STATUS_CHOICES = (
        (STATUS_PENDING, "Pending"),
        (STATUS_CONFIRMED, "Confirmed"),
        (STATUS_CANCELED, "Canceled"),
    )
    status = models.CharField(max_length=12, choices=STATUS_CHOICES, default=STATUS_PENDING)
    check_in = models.DateField()
    check_out = models.DateField()
    guest = models.ForeignKey("users.User", on_delete=models.CASCADE)
    room = models.ForeignKey("rooms.Room", on_delete=models.CASCADE)

from django.db import models
from core import models as models_core

class List(models_core.TimeStampedModel):

    """List Model Definition"""
    
    name = models.CharField(max_length=80)
    user = models.ForeignKey("users.User", on_delete=models.CASCADE)
    rooms = models.ManyToManyField("rooms.Room", blank-True)
    
    def __str__(self):
        return self.name

3. admin.py

from django.contrib import admin
from . import models

@admin.register(models.List)
class ListAdmin(admin.ModelAdmin):
    
    """List Admin Definition"""

class Conversation(models_core.TimeStampedModel):

    """Conversation Model Definition"""
    
    pasrticipants = models.ManyToManyField("users.User", blank=True)
    
    def __str__(self):
        return self.created

Message 클래스 추가

class Message(models_core.TimeStampedModel):

    "Message Model Definition"""
    
    message = models.TextField()
    user = models.ForeignKey("users.User", on_delete=models.CASCADE)
    conversation = models.ForeignKey("Conversation", on_delete=models.CASCADE)
    
    def __str__(self):
    return f"{self.user} says: {self.text}"

3. admin.py

from django.contrib import admin
from . import models

@admin.register(models.Message)
class MessageAdmin(admin.ModelAdmin):

    """Message Admin Definition"""
    
    pass


@admin.register(models.Conversation)
class ConversationAdmin(admin.ModelAdmin):

    """Conversation Admin Definition"""
    
    pass

4. migration
   
   

근데 Conversation을 생성하려니 에러가 났다.

아마 반환값이 str이 아니라서 그런것 같다.
Conversation 클래스의 반환값을 str로 변환해주자

    def __str__(self):
        return str(self.created)

됐당
