,) 'And keyword logic' {} 'were not found. When attempting to browse an article, the URL generated in the template looks correct as mentioned above (I can confirm it by searching a search through the hestack, which gives the correct URL).

models.py

  class news (models.model): id = models.IntegerField (primary_key = true, editable = false) Category = models.CharField (MAX_LENGTH = 50L) title = models.CharField (MAX_LENGTH = 200L) rss_summary = models.TextField (MAX_LENGTH = 2000L) body_text = models.TextField (MAX_LENGTH = 5000L) POST_DATE = models.DateTimeField () prettyurl = models .SlugField (MAX_LENGTH = 100 L) Square Meta: db_table = 'news' def __unicode __ (self): return self.title def get_absolute_url (auto): urlresolvers.reverse ('news_detail' kwargs = {'pk': self.id , 'Slug': self.prettyurl}) Return

  `& lt; P & gt; & Lt; A href = "{% url 'news_detail' news.slug%}" & gt; Permalink & lt; / A & gt; For this article. Thanks Daniel, Rosenman and @UV, with your help, I have defined my problem with URL patterns. By managing it:  
  r '(? P & lt; pk & gt; \ d +) (?: / (? P  [  
 News / NN  
 News / NN   
 News / NN /  
 News / NN / A- Slag  
 News / NN / A-Slug /   
 In the template, I  
  {% url 'news_detail' news.id News.prettyurl%}   
 which is the fourth number in the list listed above. Shows Krn.  
 Thanks again!
