如何在Django中将带有pk的网址重定向到带有pk和slug的网址？ [英] how to redirect a url with pk to url with pk and slug in django?

问题描述

当用户在下面输入此网址时

when a user enters this url below

www.example.com/1234

他必须重定向到

www.example.com/1234/this-is-your-first-post

例如，如果您试试这个：

For example, if you try this:

 http://stackoverflow.com/questions/15443306/

您将被重定向到

http://stackoverflow.com/questions/15443306/hover-menu-in-right-side-of-fixed-div

实际上，它不是重定向，它只是扩展 url 与 slug字段自动。

Actually it is not a redirect, it is just extending the url with slug fieldautomatically.

我要实现此功能：
这是我的模型

I want to implement this feature: Here is my models

class Article(models.Model):
    title = models.CharField(max_length=20)
    body = models.TextField()
    # image = models.ImageField(upload_to="/", blank=True, null=True)
    date = models.DateField()
    likes = models.IntegerField()
    slug = models.SlugField()

    def save(self, *args, **kwargs):
        if not self.id:
            self.slug = slugify(self.title)
        super(Article, self).save(*args, **kwargs)

    def get_absolute_url(self):
        return reverse('article_detail', kwargs={'slug':self.slug, 'pk':self.id})

    def __unicode__(self):
        return self.title

这是我的 urls.py 在我的应用内

urlpatterns = patterns('',
    url(r'all$', ArticleList.as_view(), name='blog_all'),
    url(r'^(?P<pk>\d+)/(?P<slug>[-\w\d]+)/$', ArticleDetail.as_view(), name='article_detail'),
    )

推荐答案

只需添加另一个收集信息并重定向的视图即可：

Just add another view that gathers the info and redirects:

class ArticleDetailRedirect(RedirectView):

    def get_redirect_url(self, pk):
        article = Article.objects.get(pk=pk)
        slug = article.slug
        return reverse('article_details', args=(pk, slug))

然后将其连接到您的 urls.py ：

urlpatterns = patterns('',
    url(r'all$', ArticleList.as_view(), name='blog_all'),
    url(r'^(?P<pk>\d+)/$', ArticleDetailRedirect.as_view(), name='article_redirect'),
    url(r'^(?P<pk>\d+)/(?P<slug>[-\w\d]+)/$', ArticleDetail.as_view(), name='article_detail'),
    )
