Tag detail page with Django-taggit

问题

Im trying to create pages for tags on my django blog. I already have a simple index page which displays a list of all used tags, now I want to have individual pages for each tag and on that page I will display all posts marked with that tag. The url structure for these tag detail pages will be like this

localhost/tag/my-tag-here

I already have django-taggit installed and added some tags and I have them displaying fine on post detail pages and the tag index page mentioned above but Im getting a 404 when I try to visit each tag detail page such as /tag/test.

These are my files and the full error message below.

views.py

def tag_detail(request, tag):


    tag = get_object_or_404(Tag, tag=tag.name)


    return render(request, 'blog/tags_detail.html', {'tag': tag})

urls.py (app)

urlpatterns = [

    url(r'^$', views.blog_index, name='blog_index'),
    url(r'^(?P<year>\d{4})/(?P<month>\d{2})/(?P<day>\d{2})/'\
        r'(?P<post>[-\w]+)/$',
        views.blog_post_detail,
        name='blog_post_detail'),
    url(r'^contact/$', views.contact_form, name='contact_form'),
    url(r'^thanks/$', views.thanks_view, name='thanks_view' ),
    url(r'^about/$', views.about, name='about'),
    url(r'^upload/$', views.upload_image, name='upload_image'),
    url(r'^tag/(?P<tag>[-/w]+)/$', views.tag_detail, name='tag_detail'),
    url(r'^tags/$', views.tags_index, name='tags_index')

]

and this is the full error message

Page not found (404)
Request Method: GET
Request URL:    http://127.0.0.1:8000/tag/test

is the problem here in my view or the url structure? For the view I'm not 100% sure if thats the correct way to do it but Ive tried to do it the same as my post detail view.

thanks

The problem is in your views.py file. In this code:

def tag_detail(request, tag):

    tag = get_object_or_404(Tag, tag=tag.name)

    return render(request, 'blog/tags_detail.html', {'tag': tag})

Here you wrote :

 tag = get_object_or_404(Tag, tag=tag.name)

you passed a tag in URL so correct method would be :

 tag = get_object_or_404(Tag, tag=tag)

But this will work only if, in your model,you have returned name of the tag as Unicode,Like this:

  class Tag(models.Model):
      name = models.CharField()

  def __unicode__(self):
      return unicode(self.name)

And if this still does not work then there might be a problem in TEPLATE_DIR setting in settings.py file. Then you have to share settings.py code for project file structure.
