Re: AttributeError when returning post.title in a comment model

Try '{0}-{1}'.format(var1, var2)

Check in the console in what line it's throwing the attribute error

I was working on a comment section for post and was getting an AttributeError when I return return '{}-{}'.format(self.post.title, str(self.user.username)) in the comment model

I am trying to link users and posts to the comment I am getting the same error

Here is the Models.py

class Comment(models.Model):      post = models.ForeignKey(Post, on_delete=models.CASCADE)      user = models.ForeignKey(User, on_delete=models.CASCADE)      content = models.TextField(max_length=160)      timestamp = models.DateTimeField(auto_now_add=True)        def __str__(self):          return '{}-{}'.format(self.post.title, str(self.user.username))  

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()          post = get_object_or_404(Post, slug=self.kwargs['slug'])          comments = Comment.objects.filter(post=post).order_by('-id')          total_likes = post.total_likes()          liked = False          if post.likes.filter(id=self.request.user.id).exists():              liked = True            if self.request.method == 'POST':              comment_form = CommentForm(self.request.POST or None)              if comment_form.is_valid():                  content = self.request.POST.get('content')                  comment = Comment.objects.create(                      post=post, user=request.user, content=content)                  comment.save()                  return HttpResponseRedirect("post_detail.html")          else:              comment_form = CommentForm()            context["total_likes"] = total_likes          context["liked"] = liked          context["comments"] = comments          context["comment_form"] = comment_form          return context      class PostCommentCreateView(LoginRequiredMixin, CreateView):      model = Comment      form_class = CommentForm
