让 @permalink 装饰器与 django 通用视图一起使用？

也许我遗漏了一些东西，但根据 django 文档（1.2），我已经完全按照指定设置了我的 URLS 模型，以确保我没有对 get_absolute_url 返回的 URL 进行硬编码。

这就是我所拥有的：

在 urls.py 中

urlpatterns = patterns('django.views.generic.list_detail',
    url(r'^$','object_list',
            { 'queryset': product.objects.all(),
            'template_name': 'products/list.html',
            },
            name='product_list'),  
    url(r'^(?P<slug>[-\w]+)/$','object_detail',
            { 'queryset': product.objects.all(),
            'template_name': 'products/detail.html',
            },
            name='product_detail'), 
)

在 models.py 中

@models.permalink
def get_absolute_url(self):
    return ('product_detail', (), {'slug': str(self.slug)})

该方法在模板中返回一个空字符串，并且从 shell 中给出一个错误。

NoReverseMatch: Reverse for 'product_detail' with arguments '()' and keyword arguments '{'slug': 'dd-d--'}' not found.

这应该可以解决，因为 urls.py 有一个名称：product_detail？

Maybe I am missing something, but according to the django docs (1.2), I have setup my URLS models exactly as specified to ensure I am not hard-coding urls returned for get_absolute_url.

Here's what I have:

in urls.py

urlpatterns = patterns('django.views.generic.list_detail',
    url(r'^
in models.py
@models.permalink
def get_absolute_url(self):
    return ('product_detail', (), {'slug': str(self.slug)})

The method returns an empty string in the templates, and from the shell it gives an error.
NoReverseMatch: Reverse for 'product_detail' with arguments '()' and keyword arguments '{'slug': 'dd-d--'}' not found.

This should resolve should it not, since urls.py has a name : product_detail?
,'object_list',
            { 'queryset': product.objects.all(),
            'template_name': 'products/list.html',
            },
            name='product_list'),  
    url(r'^(?P<slug>[-\w]+)/
in models.py

The method returns an empty string in the templates, and from the shell it gives an error.

This should resolve should it not, since urls.py has a name : product_detail?
,'object_detail',
            { 'queryset': product.objects.all(),
            'template_name': 'products/detail.html',
            },
            name='product_detail'), 
)

in models.py

The method returns an empty string in the templates, and from the shell it gives an error.

This should resolve should it not, since urls.py has a name : product_detail?

语法似乎是正确的，您确定您的 urls.py 已包含在内吗？尝试在视图代码中单步执行 debuggin 并首先使用 reverse 函数生成 url。

我的盲目猜测是，您的 urls.py 文件总体上有问题。

尝试更改此行：

url(r'(?P<slug>[-\w]+)/^
为
url(r'^(?P<slug>[-\w]+)/
Carret (^) 代表行的开头，因此在您编写它的上下文中这是不合逻辑的，因为这意味着该行甚至在开始之前就有内容。
,'object_detail',

Try changing this line:

url(r'(?P<slug>[-\w]+)/^
to
url(r'^(?P<slug>[-\w]+)/
Carret (^) stands for beginning of the line, so it is illogical in the context you wrote it since it means the line has content before it even begins.
,'object_detail',
