slug url 不会显示没有连字符的 url

Question

出于某种原因，我无法查看没有连字符的 slug 页面。例如：

这不起作用： /例子1

这有效： /这种方式有效

我尝试过更改正则表达式，但没有成功。任何帮助，将不胜感激！

网址

urlpatterns = patterns('',
        url(r'^$', views.index, name='index'),
        url(r'^register_profile/$', views.register_profile, name='register_profile'),
        url(r'^update_profile/$', views.update_profile, name='update_profile'),
        url(r'^create_project/$', views.CreateProject.as_view(), name='create_project'),
        url(r'^(?P<username>\w+)/$', views.profile_page, name='user_profile'),
        url(r'^(?P<slug>[-\w]+)/$', views.project_page, name='user_project'), 
        )

project_page 查看

def project_page(request, slug): 

    context_dict = {}

    username = request.user.username
    user = get_object_or_404(User, username=username)
    context_dict['project_user'] = user

    project = UserProject.objects.get(slug=slug)
    context_dict['project'] = project

    context_dict['project_title'] = project.title



    return render(request, 'howdidu/project.html', context_dict)

型号

class UserProject(models.Model):
    user = models.ForeignKey(User)
    title = models.CharField(max_length=100)
    project_overview = models.CharField(max_length=1000)
    project_picture = models.ImageField(upload_to='project_images', blank=True)
    date_created = models.DateTimeField(auto_now_add=True)
    project_views = models.IntegerField(default=0)
    project_likes = models.IntegerField(default=0)
    project_followers = models.IntegerField(default=0)
    slug = models.SlugField(max_length=100, unique=True) #should this be unique or not?

    def save(self, *args, **kwargs):
        self.slug = slugify(self.title)
        super(UserProject, self).save(*args, **kwargs)

    def __unicode__(self):
        return self.title

问题出在您的 url 订单上。

url(r'^(?P<username>\w+)/$', views.profile_page, name='user_profile'),
url(r'^(?P<slug>[-\w]+)/$', views.project_page, name='user_project'),

Django 在这些 url 中没有太大区别。 Django 将从上到下查找第一个匹配项。如果你的 slug 中有 -，它将映射到

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

因为它是唯一匹配 - 的 url。但是如果你的 slug 是 example1 link 将匹配

url(r'^(?P<username>\w+)/$', views.profile_page, name='user_profile'),

url 因为它更接近顶部。您需要做的是将另一个 'level' 添加到 url 中。例如：

url(r'^users/(?P<username>\w+)/$', views.profile_page, name='user_profile'),
url(r'^projects/(?P<slug>[-\w]+)/$', views.project_page, name='user_project'),

那么一切都会好起来的。

P. S. 您的 url 不依赖于用户，所以实际上任何用户都可以看到所有项目，我认为这不是您 need.Think 的目的，如果您需要任何帮助，请问我。
