Question

我无法配置我的网址以显示详细信息视图。点击此链接：<a href='{% url blog_detail blog.slug %}'>{{ blog.name }}</a>会显示blog.html，当我认为它会显示blog-detail.html时。没有错误，浏览器栏显示：example.com/blog/the-slug，但仍然显示来自blog.html的html，而不是blog-detail.html。有什么想法吗？谢谢你的想法。

URL：

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

的观点：

def blog(request):
    blog_list = Blog.objects.all()
    return render(request, 'blog.html', {'blog_list':blog_list})

def blog_detail(request, slug):
    blog = get_object_or_404(Blog, slug=slug)
    return render(request, 'blog-detail.html', {'blog':blog})

编辑：@omouse请求的输出

这是点击链接的输出。它与blog.html完全相同，但应为blog-detail.html。 Argggg！

Answer 1

网址是问题所在，第一个会匹配所有内容（/blog/，/blog/test/，/blog/awdlawdjaawld），您需要在结尾处使用美元符号$ 仅匹配/blog/。

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

以上应该可以正常工作。

This is a good reference for Regular Expressions

鲁道夫绝对正确

/$阻止博客捕获slug调用的所有子页面因此，如果您有子页面，则需要将/$添加到文件夹级别，如下所示：

re_path('brands/$', AllBrands.as_view(), name="brands"),
re_path(r'^brands/(?P<slug>[\w-]+)/$', BrandDetail.as_view(), name = 'brandetail'),

这是django 2.2

在品牌之后没有/$的情况下，子弹页显示的是品牌列表页。

Django Url，Slug for Detail Page
