create unique slug django


create unique slug django

Hope that helps I have a problem with creating unique slugs using django models. I want to allow the admin user to change the slug from the edit page in the admin. When a slug already exists there should be "slug + _1", "slug + _2" etc. Also when a new page is created and there is no slug given the slug should be the page title. I have this code but for some reason the admin keeps saying "Page with this Slug already exists." when I add a page with a slug that already exists. Hope somebody can help me , Try this. Didn't test it myself. But it should give you the idea.
code :
import re
def save(self, *args, **kwargs):
    if not self.id: # Create
        if not self.slug: # slug is blank
            self.slug = slugify(self.page_title)
        else: # slug is not blank
            self.slug = slugify(self.slug)
    else: # Update
        self.slug = slugify(self.slug)

    qsSimilarName = Page.objects.filter(slug__startswith='self.slug')

    if qsSimilarName.count() > 0:
        seqs = []
        for qs in qsSimilarName:
            seq = re.findall(r'{0:s}_(\d+)'.format(self.slug), qs.slug)
            if seq: seqs.append(int(seq[0]))

        if seqs: self.slug = '{0:s}_{1:d}'.format(self.slug, max(seqs)+1)

    super(Page, self).save(*args, **kwargs)

it fixes the issue I use this snippet for generating unique slug and my typical save method look like below
slug will be Django SlugField with blank=True but enforce slug in save method.
code :
def save(self, **kwargs):
    slug_str = "%s %s" % (self.title, self.us_zip) 
    unique_slugify(self, slug_str) 
    super(Need, self).save(**kwargs)

this one helps. Don't just check if that identical slug is present. Use a regular expression to count all the slugs that follow the pattern /()(-\d+)?/. Because you only allow alphanumerics your base regex above will be the slug itself.

With these it helps Of course you can simply overwrite save() method on model (or make receiver for post_save signal). It will be something like:
code :
from django.template.defaultfilters import slugify

class Deal(models.Model):
product = models.ForeignKey(Product)
slug = models.SlugField(max_length=255, unique=True)

    def save(self, *args, **kwargs):
        super(Deal, self).save(*args, **kwargs)
        if not self.slug:
            self.slug = slugify(self.product.title) + "-" + str(self.id)
            self.save()

Hope that helps I ended up using This Django Snippet to over-ride the save method of Phone in my models.py:
code :
def save(self, **kwargs):
    slug_str = "%s %s %s %s" % (self.user, self.year, self.model, self.series)
    unique_slugify(self, slug_str)
    super(Phone, self).save()

I think the issue was by ths following , In tests.py self currently refers to the class PostDetailTestCase and that class has no slug. You've almost created a post in the db that django can access.
What you need to do however is to use the following. You need to use the objects.create method in the following way.
code :
test = Post.objects.create(
    title='poost', 
    description="posting", 
    category="letstest", 
    slug='django'
)
response = self.client.get(reverse('board_detail', args=(test.slug,)))
