<DJANGO>[Hello World]

[Hello World]

안하면 이상한 찝찝한 과정...

1. 프로젝트 생성

- django-admin startproject [프로젝트명]

- cd [프로젝트명]

2. 앱 생성

- python3 manage.py startapp [앱명]

3. static, media, templates 디렉토리 생성

- mkdir static

- mkdir media

- mkdir templates

4. 기본 구조

- 프로젝트

- 기본앱

5. 프로젝트 디렉토리에서 django 설정

- settings.py

    url(r'^app001/'    , include('app001.urls', namespace='app001')    ),
] # 추가한 앱으로 url을 

6. app 구조

- urls.py가 없을 경우 생성

7. app001/urls.py

#-*- coding : utf-8 -*-
 
from django.conf.urls import url
 
from app001 import views
 
urlpatterns = [
    url(r'^$'         , views.hello_world     , name='Hello_World'  ),
]

8. app/views.py

#-*- coding : utf-8 -*-
from django.shortcuts import render
from django.http import HttpResponse
 
def hello_world(request):
    return render(request, 'hello_world.html', {})

- render와 render_to_response의 차이

https://jwkcp.github.io/2017/02/22/wtdb-render-render-to-response/

9. templates/hello_world.html

hello_world.html 파일을 만들고 Hello World를 입력;;;

나중에 extends 등을 사용해서 복잡해질 것이기에... 지금은 편하게;;;

10. 서버 실행

- python3 manage.py runserver localhost:8080

- django는 웹서버를 제공하는데 테스트용으로 사용하자.

11. Hello World 확인

- localhost:8080/app001/

- django 웹서버 로그

긴 여정이 될 것 같지만 천천히 가보도록 하자~~~
