为什么我在 Django 3.2

大佬教程收集整理的这篇文章主要介绍了为什么我在 Django 3.2，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

如何解决为什么我在 Django 3.2？

我知道已经有人问过这个问题，但没有一个解决方案特定于我正在使用的 Django 版本，即 3.2。所以我正在关注 Django 教程，但我收到了这个错误。我在 Django 中使用通用视图，就像教程一样。在使用通用视图之前，一切正常。我是否必须对我的视图进行硬编码，或者我是否错误地实现了通用视图？

这是我的代码： urls.py

from django.urls import path
from . import vIEws

app_name = "polls"
urlpatterns = [
    path("",vIEws.IndexVIEw.as_vIEw(),name="index"),path("<int:pk/",vIEws.DetailVIEw.as_vIEw(),name="detail"),path("<int:pk/results/",vIEws.ResultsVIEw.as_vIEw(),name="results"),path("<int:question_ID>/Vote/",vIEws.Vote,name="Vote" ),]

vIEws.py

from django.http import httpResponseRedirect
from django.shortcuts import get_object_or_404,render
from django.urls import reverse
from django.vIEws import generic

from .models import Choice,Question
# Create your vIEws here.
class IndexVIEw(generic.ListVIEw):
    template_name = "polls/index.HTML"
    context_object_name = "latest_question_List"

    def get_queryset(self):
        return Question.objects.order_by("-pub_date")[:5]

class DetailVIEw(generic.DetailVIEw):
    model = Question
    template_name = 'polls/detail.HTML'

class ResultsVIEw(generic.DetailVIEw):
    model = Question
    template_name = 'polls/results.HTML'

def Vote(request,question_ID):
    question = get_object_or_404(Question,pk=question_ID)
    try:
        selected_choice = question.choice_set.get(pk=request.POST['choice'])
    except (KeyError,Choice.DoesNotExist):
        return render(request,"polls/detail.HTML",{"question": question,"error_message": "You dIDn't select a choice",})
    else:
        selected_choice.Votes += 1
        selected_choice.save()   
        return httpResponseRedirect(reverse("polls:results",args=
        (question.ID,))) 

index.HTML

{% if latest_question_List %}
    <ul>
    {% for question in latest_question_List %}
        <li><a href="{% url 'polls:detail' question.ID %}">{{ question.question_text }}</a></li>
    {% endfor %}
    </ul>
{% else %}
    <p>No polls are available.</p>
{% endif %}

解决方法

path("<int:pk/",views.DetailView.as_view(),name="detail"),

path("<int:pk>/",
