send_email()은 위치 인수 하나를 받지만 3이 주어진다. - Django Python

Question

Django Python 프로젝트에서 테스트 전자 메일을 보내고 django 문서를 따르려고한다. 아래 함수가 실행될 때 오류가 발생합니다 (이미지 첨부). 내가 뭘 잘못하고 있니?

https://docs.djangoproject.com/en/2.0/topics/email/

from django.core.mail import send_mail, BadHeaderError 
from django.http import HttpResponse, HttpResponseRedirect 

    def send_email(request): 
     subject = request.POST.get('subject', 'Test') 
     message = request.POST.get('message', 'Test Message') 
     from_email = request.POST.get('from_email', 'test@example.com') 
     if subject and message and from_email: 
      try: 
       send_mail(subject, message, from_email, ['admin@example.com']) 
      except BadHeaderError: 
       return HttpResponse('Invalid header found.') 
      return HttpResponseRedirect('/contact/thanks/') 
     else: 
      # In reality we'd use a form class 
      # to get proper validation errors. 
      return HttpResponse('Make sure all fields are entered and valid.')

의견에서 지적했듯이이 코드는 관리 작업에 사용됩니다. 그러나 설명서의 Writing action functions 섹션에서 이러한 함수는 세 가지 인수를 취해야한다고 지적했습니다. 주어진 예 :

def make_published(modeladmin, request, queryset): 
    queryset.update(status='p') 

함수는 하나 개의 인수를 취하지만, 따라서 오류, 세 가지로 호출됩니다.

호출 무엇

def send_email(modeladmin, request, queryset):
