value값으로 불러오면 항상 문자열로 불러진다.
문자였을땐 공란이면 F

숫자 0는 f/ 1은 t

어퍼스트로피 ’ (｀ 이건가?) 안에 변수랑 문자열 같이 넣을 수 있는데 변수는 ${}안에 묶고

모델은 데이터베이스, 유저라는 테이블이 있어.

from django.db import models

class Person(models.Model):
    SHIRT_SIZES = (
        ('S', 'Small'),
        ('M', 'Medium'),
        ('L', 'Large'),
    )
    name = models.CharField(max_length=60)
    shirt_size = models.CharField(max_length=1, choices=SHIRT_SIZES)
>>> p = Person(name="Fred Flintstone", shirt_size="L")
>>> p.save() //db에 삽입
>>> p.shirt_size
'L'
>>> p.get_shirt_size_display()
'Large'

{% for member in totoal_member %}
{{member.userid}}
{% endfor %}

total_member에 있는 멤버를 하나 하나씩 불러온다.

{% for member in total_member %}
	아이디 : {{ member.userid }}<br>
	이름 : {{ member.username }}<br>
	<br>
	<br>
	<br>
{% endfor %}

User.objects.filter(username=req.POST.get('id'), password=req.POST.get('pw'));

-> id가 이렇고 pw가 이런 멤버가 있으면(인풋창에 입력해서) //데이터베이스 안에// 로그인이 성공된다.

def logged(req):
    logged_member = User.objects.filter(userid=req.POST.get('id'),password=req.POST.get('pw'))
        if logged_member :
            print("로그인성공")
        else :
            print("로그인실패")

실습
