Django ViewClass 2-10) DeleteView

📌DeleteView

• 기존 데이터를 삭제해주는 뷰
• 삭제 처리 후 자동으로 리디렉션 처리됨
• GET으로 접근하면 삭제 여부를 재확인하는 폼을 렌더링

Delete 뷰 클래스의 기본 형태

class DeleteView:
	model: Model
    template_name: str
    pk_url_kwarg: str
    success_url: str
    
    def get_success_url(self):
    	return success_url: str

※ get 메소드를 활용하여 DeleteView의 삭제 여부를 재확인하는 폼을 렌더링하지않고 즉시 바로 삭제 처리가 가능하도록 구현하기(UpdateView와 유사)
