Hm. I get it but it's look like there is no attribute category_set in link.
Given me this error: 'Link' object has no attribute 'category_set'
Here is my models:
#category/models.py
class Category(models.Model):
name = models.CharField("Name", max_length=100)
user = models.ForeignKey(settings.AUTH_USER_MODEL, null=True)
time = models.DateTimeField(auto_now_add=True)
slug = models.SlugField(max_length=100)
objects = models.Manager()
def __str__(self):
return self.name
def get_absolute_url(self):
return reverse('category:category_detail', kwargs={"name": self.name,})
#links/models.py
class Link(models.Model):
title = models.CharField("Headline", max_length=100)
submitter = models.ForeignKey(settings.AUTH_USER_MODEL, null=True)
submitted_on = models.DateTimeField(auto_now_add=True)
rank_score = models.FloatField(default=0.0)
url = models.URLField("URL", max_length=250)
category = models.ForeignKey(Category, null=True)
description = models.TextField(blank=True)
slug = models.SlugField(unique=True)
img = models.ImageField(upload_to="thumbnail/", blank=True)
image_og = models.ImageField(upload_to="thumbnail/", blank=True, default
="/static/images/entry/default.png")
with_votes = LinkVoteCountManager()
objects = models.Manager()
def __str__(self):
return self.title
def get_absolute_url(self):
return reverse('link:link_detail', kwargs={"category": self.category
.slug, "slug": self.slug,
'pk': str(self.id)
})
....
