CRUD with views

READ

• url 설정

app_name = 'articles'
urlpatterns = [
    path('', views.index, name='index'),
]

• view 함수 작성

def index(request):
    # 전체 게시글 조회(오름차순)
    # articles = Article.objects.all()

    # 전체 게시글 조회(내림차순 1, python으로 조작)
    # articles = Article.objects.all()[::-1]
    
    # 전체 게시글 조회(내림차순 2, DB가 조작)
    articles = Article.objects.order_by('-pk')

    # 조회해서 할당한 쿼리셋 데이터를 context로 넘김
    context = {
        'articles': articles,
    }
    return render(request, 'articles/index.html', context)

• templates 작성

{% block content %}
  <h1>Articles</h1>
  <a href="{% url 'articles:new' %}">NEW</a>
  <hr>
  {% for article in articles %}
    <p>글 번호: {{ article.pk }}</p>  
    <p>글 제목: {{ article.title }}</p>
