I am trying to switch from writing the id:pk of the blog to writing a function to add the post title to become a slug.
So I am currently trying to switch all my post details to slug but after I finished everything I am getting a page error 404 which doesn't indicate exactly where I have something wrong with my code.
My question is when I move from changing the URLs from int:id to slug what should I be looking for to change as well to avoid page error 404?
In the URL for every page detail, I am getting the int:id not the title of the post and the error 404
I am doubting the get_absolute_url
I have commented the addition of the slug function: Here is the models.py :
class Post(models.Model):
designer = models.ForeignKey(User, on_delete=models.CASCADE)
title = models.CharField(max_length=100)
likes = models.ManyToManyField(
User, related_name='liked')
slug = models.SlugField(blank=True, null=True, max_length=120)
def save(self, *args, **kwargs):
if not self.slug:
self.slug = slugify(self.title)
super(Post, self).save(*args, **kwargs)
def get_absolute_url(self):
return reverse("score:post-detail", kwargs={'slug': self.slug})
Here is the views.py
class PostDetailView(DetailView):
model = Post
template_name = "post_detail.html"
def get_context_data(self, *args, **kwargs):
context = super(PostDetailView, self).get_context_data()
stuff = get_object_or_404(Post, id=self.kwargs['slug'])
total_likes = stuff.total_likes()
liked = False
if stuff.likes.filter(id=self.request.user.id).exists():
liked = True
context["total_likes"] = total_likes
context["liked"] = liked
return context
def LikeView(request):
post = get_object_or_404(Post, id=request.POST.get('id'))
liked = False
if post.likes.filter(id=request.user.id).exists():
post.likes.remove(request.user)
liked = False
else:
post.likes.add(request.user)
liked = True
context = {
'total_likes': post.total_likes,
'liked': liked,
'post': post
}
if request.is_ajax:
html = render_to_string('like_section.html', context, request=request)
return JsonResponse({'form': html})
here is the url
urlpatterns = [
path('', PostListView.as_view(), name='score'),
path('<slug:slug>/', PostDetailView.as_view(), name='post-detail'),
path('new/', PostCreateView.as_view(), name='post-create'),
path('user/<str:username>', UserPostListView.as_view(), name='user-posts'),
path('<slug:slug>/update/', PostUpdateView.as_view(), name='post-update'),
path('<slug:slug>/delete/', PostDeleteView.as_view(), name='post-delete')
your `get_absolute_url' setup is wrong, PFB the sample ,
Step 1:
def get_absolute_url(self):
return reverse("app_name:detail", kwargs={"slug": self.slug})
Step 2:
In URL.py
app_name = 'blogs'
path('blog/<slug:slug>/', view.detail,name='detail'),
Steps 3:
We should have view for this.
yes i know.. what i am saying is problem in URL & get_absolute_url method. If you see the sample which i sent you could understand better

def get_context_data(self, *args, **kwargs):
context = super(PostDetailView, self).get_context_data()
stuff = get_object_or_404(Post, id=self.kwargs['pk']) <--- Error from here
total_likes = stuff.total_likes()
liked = False
if stuff.likes.filter(id=self.request.user.id).exists():
liked = True
context["total_likes"] = total_likes
context["liked"] = liked
return context
```

yes CBC or generic view doesnt matter. you need to point the name in URL,
path('blog/<slug:slug>/', BlogDetailView.as_view(),name='detail'), . like this

we have already shared the code. you just need to replace with your app name & view name.. thats it

Ok just bare with here are the final amendments I made and if there is anything wrong please inform me
in the urls
path('<slug:slug>/', PostDetailView.as_view(), name='post-detail'),
in the models
def get_absolute_url(self):
return reverse("score:post-detail", kwargs={'slug': self.slug})
in the views.py ``` stuff = get_object_or_404(Post, id=self.kwargs['slug']) <--- Error shows from here
```
