Why doesn't ModelAdmin work?

Question

Django

from django.contrib import admin
from django.urls import path
from django.shortcuts import render
from .models import Question , Out_questiom
admin.site.register(Question) 

class SendAnswerAdmin(admin.ModelAdmin):
  def get_urls(self):
    urls = super().get_urls()
    my_urls = [
      path('answer/',self.admin_site.admin_view(self.answer_get)),
      path('answer/create/', self.admin_site.admin_view(self.answer_out)),
    ]
    return my_urls + urls
  def answer_get(self,request):
    question_list = Question.objects.order_by('date_time_create')
    return render(request,'admin/answer_admin_change.html')
  
  def answer_out(self,request):
    if request.method == "POST":
      answer_question = Question.objects.order_by('date_time_create')
      text_answer = request.POST.get("text_answer")
      send_mail('Ответ', text_answer, 'xxx',
        [answer_question.email], fail_silently=False)
      new_answer = Out_answer(
        email_answer = answer_question.email,
        name_person_answer = answer_question.name_person,
        theme_question_answer = answer_question.theme_question,
        full_text_answer = text_answer,
        full_text_answer_old = answer_question.full_text_answer,
        created_time_quest_old = answer_question.created_time_quest,
      )
      answer_question.delete()
      new_answer.save()
admin.site.register(Out_questiom , SendAnswerAdmin)

I just don't understand, I seriously admit that I'm stupid and helpless. py manage.py runserver runs without error,
but when I try to go to 127.0.0.1:8000/admin/question/sendanswer/answer it gives me a 404 error. In the console of information 0. Help.
