알아야 할것들

Django ORM

create(), get(), filter(), delete()

from django.db import models
# 모델 생성
class Cat(models.Model):
    name = models.CharField(max_length=30)
    brees = models.CharField(max_length=30)

# 오브젝트 생성
Cat.object.create(
    name="Fluffy",
    breed="Perian"
)

# 검색
## 아이디를 이용한 검색 및 수정
cat = Cat.objects.get(id=1)
fluffy.name = "Mr. Fluffy"
fluffy.save()

## 필터를 이용한 검색
british_cats = Cat.objects.filter(breed="British")

## 필터 Lookups options = startwith, contains, istartswith, icontainsm, lt , gt, ...
cats = Cat.objects.filter(name__startswith="Mr")
cats = Cat.objects.all()

# delete()
fluffy = Cat.objects.get(id=1)
fluffy.delete()

# foreignKey 모델에 생성
class Owner(models.Model):
    name = models.CharField(max_length=100)
    last_name = models.CharField(max_length=100)
    age = models.IntegerField()
    following = models.ManyToManyField('self')
    followers = models.ManyToManyField('self')

# 외래키 설정하기
from . import Owner
owner = models.ForeignKey(Owner, null=True)

# 저장방법
king = Owner.objects.create(name="king", last_name="lim", age=45)
bunns = Cat.objects.get(id=2)
bunns.owner = king
bunns.save()

# 데이터 접근방법
bunns = Cat.objects.get(id=2)
print(bunns.owner.age)

king = Owner.objects.get(pk=1)
king_cats = king.cat_set.all()
