SlugField中的连字符 [英] Hyphens in SlugField

问题描述

所以，这是一个奇怪的错误，当我打开带有连字符的URL在SlugField，虽然SlugField支持连字符，如文档中所示。错误：

 找不到页面（404）
请求方法：GET 
请求URL：http： /127.0.0.1:8003/dumpster-rental-prices 
使用dumpster.urls中定义的URLconf，Django按以下顺序尝试了这些URL模式：
 ^ admin / 
 ^（？P< ; slug> \w +）/ $ 
当前URL，dumpster-rental-prices与这些没有匹配。 
  

如果我将文章的小块更改为dumpster_rental_prices - url 127.0.0.1:8003/dumpster_rental_prices打开

这是博客应用的models.py：

 从django.db导入模型
 
 class Post（models.Model）：
 title = models.CharField（max_length = 100）
 body = models.TextField（max_length = 5000） 
 slug = models.SlugField（max_length = 100）
 
 def __unicode __（self）：
 return self.title 
  

这是博客foder中的urls.py：

  from django .conf.urls import pattern，include，url 
 from django.views.generic import DetailView，ListView 
 from blog.models import Post 
 
 from django.contrib import admin 
 admin.autodiscover（）
 
 urlpatterns = patterns（''，
 url（r'^（？P< slug> \w +）/ $'，
 DetailView .as_view（
 model = Post，
t emplate_name ='detail.html'）），
 
）
  

谢谢提前为您的帮助。

解决方案

问题是您的正则表达式 - \w 只匹配字母数字字符和下划线。如果你想匹配连字符，你需要像 r'^（？P< slug> [\w - ] +）/ $ 的东西。

There is a strange error when i open a URL with hyphens in the slug, though SlugField supports hyphens in it as indicated in documentation.

So, this is the error:

Page not found (404)
Request Method: GET
Request URL:    http://127.0.0.1:8003/dumpster-rental-prices
Using the URLconf defined in dumpster.urls, Django tried these URL patterns, in this order:
^admin/
^(?P<slug>\w+)/$
The current URL, dumpster-rental-prices, didn't match any of these.

If i change the slug of the article to dumpster_rental_prices - the url 127.0.0.1:8003/dumpster_rental_prices opens fine.

This is models.py of blog app:

from django.db import models

class Post(models.Model):
    title = models.CharField(max_length = 100)
    body = models.TextField(max_length = 5000)
    slug = models.SlugField(max_length = 100)

    def __unicode__(self):
        return self.title

This is urls.py in blog foder:

from django.conf.urls import patterns, include, url
from django.views.generic import DetailView, ListView
from blog.models import Post

from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^(?P<slug>\w+)/$',
        DetailView.as_view(
            model=Post,
            template_name='detail.html')),    

)

Thank you in advance for your help.

解决方案

The problem is your regex - \w only matches alphanumerical characters and underscores. You need something like r'^(?P<slug>[\w-]+)/$ if you want to match hyphens as well.
