Django redirect URL to latest created blog post

问题

I want to have a redirect in my urls.py so that the latest Post entry in my Blog application is automatically loaded when people visit the Blog application index domain.

A Blog.Post detail is supplied via the blog.views.post_detail(request, slug) method and a blog post will end up with the URL:

www.example.com/blog/this-is-the-slug/

When someone loads the www.example.com/blog domain I want them to be automagically redirected to the latest blog post individual entry.

I'm very new to the urls.py and can't work out how to do this. I realise it would be fairly rudimentary.

回答1:

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


def redirector(request):
     blog = Blog.objects.latest('id')
     return http.HttpResponseRedirect(reverse('blog_detail', args=[blog.slug]))

Alternative option, some people dislike reverse because it fails loudly.

You can define a get_absolute_url method on your blog post model that returns the absolute url, then your redirect is as simple as http.HttpResponseRedirect(Blog.objects.latest('id').get_absolute_url())
