**i can’t generate slug to my post model**

model

```auto
class Post(models.Model):
    id = models.UUIDField(default=uuid.uuid4, editable=False, unique=True, primary_key=True)
    slug = models.SlugField(max_length=200, db_index=True, unique=True, editable=False) # add unique=True in slug (never repeat)
    title = models.CharField(max_length=200, db_index=True, blank=False, default='')
    snippet = models.OneToOneField(Snippet, on_delete=models.CASCADE, related_name='post_snippets', blank=True, null=True)
    creator = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name="post_creator")
    ...
    def get_absolute_url(self):
        """Returns the url to access a particular post instance."""
        return reverse('details', kwargs={ "id": str(self.id), "slug": self.slug})
    def save(self, *args, **kwargs):
        if not self.slug:
            self.slug = slugify(self.title)
        img = Image.open(self.post_img.path)
        return super(Post, self).save(*args, **kwargs)

```

my form

```auto
class PostForm(forms.ModelForm):
    class Meta:
        model = Post
        exclude = ('creator', 'snippet')

class SnippetForm(forms.ModelForm):
    class Meta:
        model = Snippet
        fields = ' __all__'

```

my view

```auto
@login_required
def add_post(request):
    if request.method == 'POST':
        post_form = PostForm(request.POST, request.FILES)
        snippet_form = SnippetForm(request.POST)
        if post_form.is_valid() and snippet_form.is_valid():
            post = post_form.save(commit=False)
            snpt = snippet_form.save()
            post.creator = request.user
            post.snippet = snpt
            post.save()
            snpt.save()
            return redirect('blog:index')
    else:
        post_form = PostForm()
        snippet_form = SnippetForm()
    return render(request, 'blog/add_post.html', {'post': post_form, 'snpt': snippet_form})

```

**what’s wrong in this logic that cause slug to not be generated**  
i have tried in admin.py  
`prepopulated_fields = {'slug': ('title',)}`  
**but it gives**  
"KeyError at /admin/post/add/ "Key ‘slug’ not found in ‘PostForm’. Choices are: other fields

**i really confused on what to do for it to be exist in admin page**  
**I removed the save method from my model and let only the perpetuated line or vice versa but same thing. Do and add some logic in views functions???**

You’ve defined [`editable=False`](https://docs.djangoproject.com/en/4.1/ref/models/fields/#editable) in the field definition.

```

**and the url**

`path('posts/<str:slug>/<int:pk>/', post_details, name='details'),`

**and the get\_absolute\_url as above**

**this is the pattern name i have named in my url so it’s valid as i think, i think there is something else is causing this, if you don’t have an idea what is it, i will try to rethink and look again on this return reverse**

**i thought that you will find it just by naked eye as you are an expert without having to search on stack or take some time but i have to do some search and think again, anyway thanks bro**

What is your _complete_ urls.py file containing this entry?

**This** is what’s missing in your call to reverse:

> [@Abunagy](#):
>
> `app_name='blog'`

This app\_name creates a “namespace” for your urls. You need to prefix the url name references with this app\_name, similar to what you have here:

> [@Abunagy](#):
>
> `<a href="{% url 'posts:details' post.id %}">`

(But with `blog` instead of `posts`)

It’s what I refer to as the “eye for details” - it’s something you work on, develop, and enhance as you gain experience.
