    path('new/', views.new, name='new'),
    path('create/',views.create, name='create'),

# articles > views.py

    article = Article()
    article.title = title
    article.content = content
    article.save()

    # return redirect('주소','argument나 변수들','')
    return redirect('articles:detail', article.pk)

# 여기서 pk는 variable routing 변수이다

    # 조회를 먼저 
    # 몇번 글 삭제할거야?
    article = Article.objects.get(pk=pk) 
    article.delete()
    return redirect('articles:index')

# render는 페이지 주기
# redirect는 되돌리기
