django - How to make it such that if comments have been edited before, an "edited" permanent message will be displayed beside the comment?

Question

How to make it such that if comments have been edited before, an "edited" permanent message will be displayed beside the comment? So that everyone will be able to see that the comment has been edited before. (it'll be good if i can keep a copy of the original pre-edited message too, but if thats too difficult, i'm just hoping to display an "edited" permanent message will be displayed beside the comment.

models.py

class Comment(models.Model):
   post = models.ForeignKey(BlogPost, related_name='comments', on_delete=models.CASCADE)
   name = models.ForeignKey(settings.AUTH_USER_MODEL, related_name='name', on_delete=models.CASCADE)
   body = models.TextField()

class BlogPost(models.Model):
 title                  = models.CharField(max_length=50, null=False, blank=False, unique=True)
 author                     = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
 slug                   = models.SlugField(blank=True, unique=True)

views.py

def edit_own_comment(request, post_id):
    context = {}
    comment = get_object_or_404(Comment, id=post_id)
    if request.method == 'POST':
        form = UpdateCommentForm(request.POST or None, instance=comment)
        if form.is_valid():
            obj.save()
            messages.success(request, 'Your comment has been edited', extra_tags='editedcomment')
            return redirect(reverse("HomeFeed:detail", kwargs={'slug': comment.post.slug }))

    form = UpdateCommentForm(
            initial = {
                    "body": comment.body,
            }
        )

    context['form'] = form
    return render(request, 'HomeFeed/edit_comment.html', context)


class DetailBlogPostView(BlogPostMixin,DetailView):
    template_name = 'HomeFeed/detail_blog.html'
    
    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        blog_post=self.get_object()
        blog_post.save()

forms.py

class UpdateCommentForm(forms.ModelForm):
 class Meta:
  model = Comment
  fields = ['body']

 def save(self, commit=True):
  comment = self.instance
  comment.body = self.cleaned_data['body']

  if commit:
   comment.save()
  return comment

detail.html

  {% for comment in blog_post.comments.all %}
    {{ comment.name}}
  {{ comment.body }}
  {% endfor %}

Well Ankush described the best possible solution you can have, add this to your Comment model:

edited = models.BooleanField(default=False)

Then in your view whenever the comment gets edited before calling comment.save() do this:

comment.edited = True

And in your html where you list comments do this:

{% for comment in comments %}
    <p>{{ comment.name }} : {{ comment.body }}</p>
    {% if comment.edited %}
        <p>edited</p>
    {% endif %}
{% endfor %}
