如何解决我的网站在本地服务器上运行良好，但在“pythonanywhere.com”上部署它时，我收到“NoReverseMatch at /”错误
我正处于学习 Web 开发的初始阶段（来自 django 女孩）。我创建了一个视图“post_new”并将其链接到模板“post_edit.html”。当我在笔记本电脑上的本地服务器上运行我的网站时，它工作正常，但在 pythonanywhere.com 上部署它时，出现错误：
noreverseMatch at /
Reverse for 'post_new' not found. 'post_new' is not a valid view function or pattern name.
Request Method: GET
Request URL: http://sahilkumar.pythonanywhere.com/
Django Version: 2.2.19
Exception Type: noreverseMatch
Exception Value:
Reverse for 'post_new' not found. 'post_new' is not a valid view function or pattern name.

使用此“post_new”视图的文件是：
{% load static %}
<!DOCTYPE html>
<html>
<head>
<title>Sahil's Website</title>
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@4.5.3/dist/css/bootstrap.min.css" integrity="sha384-TX8t27EcRE3e/ihU7zmQxVncDAy5uIKz4rEkgIXeMed4M0jlfIDPvg6uqKI2xXr2" crossorigin="anonymous">

</head>
<body>
<div class="heading">
<h1>Sahil's Writings</h1>
</div>
{% if user.is_authenticated %}
<a href = "{% url 'post_new' %}" class="top-menu">
{% include './icons/file-earmark-plus.svg' %}
</a>
{% endif %}
<main >
<div >
<div >
{% block content %}
{% endblock %}
</div>
</div>
</main>
</body>
</html>
我的 view.py 文件看起来像：
from django.shortcuts import render,get_object_or_404
from django.utils import timezone
from .models import Post
from .forms import PostForm
from django.shortcuts import redirect
# Create your views here.
def post_edit(request,pk):
post = get_object_or_404(Post,pk=pk);
if request.method == "POST":
form = PostForm(request.POST,instance=post)
if form.is_valid():
post = form.save(commit=False)
post.author = request.user
post.published_date = timezone.Now()
post.save()
return redirect('post_detail',pk=post.pk)
else:
form = PostForm(instance=post)
return render(request,'blog/post_edit.html',{'form':form})
def post_detail(request,pk=pk);
return render(request,'blog/post_detail.html',{'post':post})
def post_list(request):
posts = Post.objects.filter(published_date__lte=timezone.Now()).order_by('published_date')
return render(request,'blog/post_list.html',{'posts':posts})
def post_new(request):
if request.method == 'POST':
form = PostForm(request.POST)
if form.is_valid():
post = form.save(commit=False)
post.author = request.user
post.published_date = timezone.Now()
post.save()
return redirect('post_detail',pk=post.pk)
else:
form = PostForm()
return render(request,{'form': form})
我的 urls.py 文件如下所示：
from django.urls import path
from . import views
urlpatterns = [
path('',views.post_list,name='post_list'),path('post/<int:pk>/',views.post_detail,name='post_detail'),path('post/new/',views.post_new,name='post_new'),path('post/<int:pk>/edit/',views.post_edit,name='post_edit'),]
有人能帮我找出我哪里出错了吗？
