Reference comment count on different using Django - django

Question

I have a BlogPage that references all my blogs with snippets of text. These can be clicked to view the full blog on a ViewBlog page, at the bottom of the view-blog page you can add a comment, and all comments are subsequently shown on this page.
I want to be able to reference the amount of comments made on every post some where on the snippet box on the blog page as screenshot below shows (I don't require help with the code for this, only the code to be able to reference it on the BlogPage;
MODELS.PY
class BlogPost(models.Model):
title = models.CharField(max_length=100, null=False, blank=False, default="")
text = RichTextUploadingField(null=True, blank=True, default="text")
featured_text = models.TextField(max_length=550, null=True, blank=True, default="text")
image = models.ImageField(null=True, blank=True, upload_to="images", default="default.png")
date = models.DateField(auto_now_add=True)
published = models.BooleanField(default=False)
featured = models.BooleanField(default=False)
slug = models.SlugField()
def save(self, *args, **kwargs):
self.slug = self.slug or slugify(self.title)
super().save(*args, **kwargs)
def __str__(self):
return self.title
class BlogComment(models.Model):
post = models.ForeignKey(BlogPost, related_name="comments", on_delete=models.CASCADE)
name = models.CharField('Name',max_length=100, default="")
text = models.TextField('Comment',max_length=1000, default="")
date = models.DateTimeField(auto_now_add=True)
status = models.BooleanField(default=True)
class Meta:
ordering = ("date",)
def __str__(self):
return '%s -- Name: %s'%(self.post.title, self.name)

def BlogPage(request):
posts = BlogPost.objects.filter(date__lte=timezone.now()).order_by('-date')
blog_paginator = Paginator(posts, per_page=4)
page_number = request.GET.get('page')
page = blog_paginator.get_page(page_number)
context = {'page': page}
return render(request, 'mhpapp/blog.html', context)
def ViewBlog(request, slug):
try:
blog = BlogPost.objects.get(slug=slug)
except BlogPost.DoesNotExist:
print("Blog with this slug does not exist")
blog = None
comments = blog.comments.filter(status=True)
user_comment = None
if request.method == 'POST':
comment_form = CommentForm(request.POST)
if comment_form.is_valid():
user_comment = comment_form.save(commit=False)
user_comment.post = blog
user_comment.save()
else:
comment_form = CommentForm()
return render(request, 'mhpapp/view-blog.html', {'blog': blog, 'slug': slug, 'comments': user_comment, 'comments': comments, 'comment_form': comment_form})

Answer 1

You can use the reverse relation from Comment to Blog like blog.comments.all().count() will return all comments related to a blog. You could probably use a method on your Blog model:
#property
def comment_count(self):
return blog.comments.all().count()
And in your template you can then use this property to show the amount of comments.
