장고로 설치부터 앱만들기 까지 배웠다. 8시간?동안 너무 빨리 나가서 복습을 해도 아직 잘모르겠다.
- 장고 설치 및 데이터베이스 생성
pip install django
django-admin startproject config .
python manage.py migrate(기본 데이터베이스 생성)
python manage.py createsuperuser(계정생성)
python manage.py runserver/admin -> urls에 등록되어있다
- 앱 생성
python manage.py startapp bookmark(앱 생성)- 앱 추가
settings.py 에 앱 추가
'bookmark',- models.py에 클래스 추가(형식 지정)
from django.db import models
class Bookmark(models.Model):
site_name = models.CharField(max_length=100)
url = models.URLField('Site URL')
def __str__(self):
return "이름 : " + self.site_name + ", 주소 : " + self.url-
python manage.py makemigrations bookmark(데이터 넣을 공간 생성)
-
python manage.py migrate(읽어오기)
-
admin.py
from django.contrib import admin
from .models import Bookmark
admin.site.register(Bookmark)- views.py(리스트 뷰 만들기)
from django.views.generic.list import ListView
from.models import Bookmark
(models에서 만든 클래스 불러오면된다... 다가져오려면 * 붙이면된다)
클래스 생성하기
class BookmarkListView(ListView):
model = Bookmark- bookmark/urls.py 생성 및 config/urls.py에 bookmark urls 추가
path('bookmark/', include("bookmark.urls"))bookmark/urls 에
from django.urls import path
from .views import BookmarkListView
urlpatterns = [
path('', BookmarkListView.as_view(), name='list')
]
