[Django] 초간단 사용자정의 Member 회원가입, 로그인, 로그아웃 만들기

GitHub - wonpaper/Django_SimpleCustomMemberLogin: Django 초간단 사용자 정의 회원가입, 로그인, 로그아웃

 

Django 에는 자체적으로

django.contrib.auth

 

from django.contrib.auth.models import AbstractUser

등을 통하여 User 에 대한 사용자 정의 Custom 모델을 제공하고 있다.

 

하지만, 본 포스팅은 필자가 별도로 아주 간단한 member 테이블을 임의로 만들고, 세션 방식으로 로그인/로그아웃 기본적으로 만들어 보았다.

 

DB는 자제 sqlite3 에서, 별도로 member 기본 회원테이블을 간략히 아래와 같이 구성하였다.

 

그리고, Django 프로젝트를 간단히 하나 만든다.

django-admin startproject 앱이름

그리고, member 앱을 생성하였다.

python manage.py startapp member

25라인의 소스는 Templates html 에서도 세션을 이용가능하도록 하는 기능이니 반드시 추가하도록 하자.
