标签: slugify

我正在尝试使用我安装的slugifypip3 install slugify.但是,在解释器中,如果我尝试敲击字符串,'hello'我会看到以下内容:

Python 3.5.2 (default, Nov 17 2016, 17:05:23)

In [1]: from slugify import slugify

In [2]: slugify('hello')
---------------------------------------------------------------------------
NameError                                 Traceback (most recent call last)
<ipython-input-2-a58110f37579> in <module>()
----> 1 slugify('hello') …

在这种情况下使用 slug 并使其正常工作的最佳方法是什么。我可以看到浏览器上的 URL 显示了请求的项目，但我无法呈现详细页面。我找不到问题的出处。当我访问“page_detail”时，url 是“ http://127.0.0.1:8000/posts/2019/03/23/greetings/ ”，根据我的输入这是正确的，但 django 会抛出一个错误来呈现页面。错误是： TypeError: post_detail() got an unexpected keyword argument 'slug'

模型：

class Post(models.Model):
       STATUS_CHOICES = (
           ('draft', 'Draft'),
           ('published', 'Published'),
       )
       title = models.CharField(max_length=250)
       slug = models.SlugField(max_length=250,
                               unique_for_date='publish')
       author = models.ForeignKey(User, on_delete = models.CASCADE, related_name='blog_posts')
       body = models.TextField()
       publish = models.DateTimeField(default=timezone.now)
       created = models.DateTimeField(auto_now_add=True)
       updated = models.DateTimeField(auto_now=True)
       status = models.CharField(max_length=10,
                                 choices=STATUS_CHOICES,
                                 default='draft')

       published = PublishedManager()   # Custom Model Manager

       def get_absolute_url(self):
        ''' Canonical URL for post detail.'''
        return reverse('snippets:post-detail',
                        args=[self.publish.year,
                                self.publish.strftime('%m'),
                                self.publish.strftime('%d'), …
