【问题描述】：
快速信息我是 python 和 django 的初学者。
这是一个问题：
我正在尝试使用 django 创建简单的博客应用程序，我已经创建了所有需要的内容，并且我能够呈现我的一个主页但是当我尝试访问帖子页面时（能够查看当前帖子) 我收到以下错误：
Request Method: GET
Request URL: http://localhost:8000/posts/
Django Version: 2.0.2
Exception Type: NoReverseMatch
Exception Value:
Reverse for 'post' not found. 'post' is not a valid view function or pattern name.
我不确定为什么会收到此错误，因为我已经编写了可访问的帖子视图功能，这是我的文件：
my_blog/urls.py
"""Defines URL patterns for my_blog."""
from django.conf.urls import url
from . import views
#needed app name
app_name='my_blog'
urlpatterns=[
#Homepage
url(r'^$',views.home,name='home'),
# Show all posts.
url(r'^posts/$', views.posts, name='posts'),
models.py
from django.db import models
# Create your models here.
class BlogPost(models.Model):
"""Post that can be viewed"""
title=models.CharField(max_length=200)
text=models.TextField()
date_added=models.DateTimeField(auto_now_add=True)
def __str__(self):
"""Return a string representation of the model."""
if len(self.text)<50:
return self.text
else:
return self.text[:50] + "..."
views.py
from django.shortcuts import render
from .models import BlogPost
from django.http import HttpResponseRedirect
# Create your views here.
def home(request):
"""The home page for Learning Log"""
return render(request,'my_blog/home.html')
def posts (request):
"""Show all posts."""
posts=BlogPost.objects.order_by('date_added')
context={'posts':posts}
return render(request, 'my_blog/posts.html', context)
HTML 页面：
home.html
{%extends "my_blog/base.html"%}
{%block content%}
<html>
<p align="center">Welcome to my Blog</p>
</body>
</html>
{%endblock content%}
base.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>My Blog</title>
</head>
<body bgcolor="#85C1E9">
<p>
<a href="{%url 'my_blog:home'%}">Home</a> -
<a href="{%url 'my_blog:posts'%}">Posts</a>
</p>
{%block content%}{%endblock content%}
</body>
</html>
posts.html
{%extends "my_blog/base.html"%}
{%block content%}
<p>Posts</p>
<ul>
{%for post in posts%}
<li><a href="{%url 'my_blog:post' post.id%}">{{post}}</a> </li>
{%empty%}
<li>No posts have been added yet.</li>
{%endfor%}
</ul>
{%endblock content%}
提前感谢您的帮助
