let say the user chooses the name "Elsa Frozen" now his slug would be "Elsa-Frozen-5"
it means 4 other people have used the same header now he can go to url: "your website.com/Elsa-Frozen-4" to see other people's Post
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 | from django.utils.text import slugify
class Post(models.Model):
header = models.CharField(max_length=50)
slug = models.SlugField(unique=True, db_index=True)
def __str__(self):
return self.header
def get_absolute_url(self):
return reverse("post-detail", kwargs={"slug": self.slug})
def unique_slug_generator(instance):
constant_slug = slugify(instance.header)
slug = constant_slug
num = 0
Klass = instance.__class__
while Klass.objects.filter(slug=slug).exists():
num += 1
slug = "{slug}-{num}".format(slug=constant_slug, num=num)
return slug
