Django Handling Http Request

하나의 URL 에서 GET 과 POST 를 각각 다르게 처리

new, create 함수 결합

As-is

# articles/views.py

def new(request):
    form = ArticleForm()
    context = {
        'form': form,
    }
    return render(request, 'articles/new.html', context)


def create(request):
    form = ArticleForm(request.POST)
    if form.is_valid():
        article = form.save()
        return redirect('articles:detail', article.pk)
    context = {
        'form': form,
    }
    return render(request, 'articles/new.html', context)

To-be

# articles/views.py

def create(request):
    if request.method == 'POST':
        form = ArticleForm(request.POST)
        if form.is_valid():
            article = form.save()
            return redirect('articles:detail', article.pk)
    else:
        form = ArticleForm()
    context = {
        'form': form,
    }
    return render(request, 'articles/create.html', context)

# articles/urls.py

app_name = 'articles'
urlpatterns = [
    path('', views.index, name='index'),
    path('<int:pk>/', views.detail, name='detail'),
    # path('new/', views.new, name='new'),
    path('create/', views.create, name='create'),
    path('<int:pk>/delete/', views.delete, name='delete'),
    path('<int:pk>/edit/', views.edit, name='edit'),
    path('<int:pk>/update/', views.update, name='update'),
]

html 파일들에 있는 new url -> create 로 변경

• GET articles/create/ : 게시글 생성 페이지 접속
• POST articles/create/ : 게시글 생성
