Django中的lug lug lug l [英] Slug Url Regex in Django

问题描述

阅读了很多关于正确使用s lug从对象列表创建详细信息视图之后。但是，我仍然有问题让它为我工作。我在我的模板中显示对象列表，如：

  {％for thing in thing_list％} 
< div class ='thing-detail'>< a href ='{％url detail％}'>< img src ='theimage.png'/> 
 {％endfor％} 
  

但是我得到一个 NoReverseMatch 错误细节。

我认为我的正则表达式有问题，或者只是一个更好的方法，我失踪了。

正则表达式：

  url（r'^ thing /（？P< slug> [\w - ] +）/ $'，'views.detail'，name ='detail'），
  

查看：

  def detail（request，slug）：
 thing = get_object_or_404（Thing，slug = slug）
 return render（request，'detail.html'，{'thing'：thing}）
  

型号：

  class Thing（models.Model）：
 user = models.ForeignKey（User）
 created_on = models.DateTimeField（auto_now_add = True）
 slug = models.SlugField（）
 
 def save（self，** kwargs）：
 slug ='％s'％ （self.user）
 unique_slugify（self，slug）## from http://djangosnippets.org/snippets/1321/ 
 super（Thing，self）.save（）
  

谢谢你ping！

解决方案

你没有传递任何参数来构建 detail 网址。你可能想这样做：

  {％urldetailthing.slug％} 
  

哪些将创建一个详细信息 URL，并填入给定的插槽。 >


After reading a lot about proper use of a slug to create a detail view from a list of objects. However, I am still having problems getting it to work for me. I am displaying a list of objects in my template like:

{% for thing in thing_list %}
   <div class='thing-detail'><a href='{% url detail %}'><img src='theimage.png' />
{% endfor %}

But am getting a NoReverseMatch error on detail.

I figure that there is either something wrong with my regex, or there is just a better way of doing this that I am missing.

Regex:

url(r'^thing/(?P<slug>[\w-]+)/$', 'views.detail', name='detail'),

View:

def detail(request, slug):
    thing = get_object_or_404(Thing, slug=slug)
    return render(request, 'detail.html', {'thing': thing})

Model:

class Thing(models.Model):
    user = models.ForeignKey(User)
    created_on = models.DateTimeField(auto_now_add=True)
    slug = models.SlugField()

    def save(self, **kwargs):
        slug = '%s' % (self.user)
        unique_slugify(self, slug)  ## from http://djangosnippets.org/snippets/1321/
        super(Thing, self).save()

Thank you for helping!

解决方案

You're not passing any arguments to build the detail URL. You probably want to do this:

{% url "detail" thing.slug %}

Which will create a detail URL with the given slug filled in.
