My comments are not being displayed in a django blog

Question

I am trying to add a comment section to add a comment section to my blog detail using django but when i run my server i get no error in the development server and the comments are not being displayed. I added the comments from my admin site. The snippet of my code is below.

views.py

from .models import Post
from django.utils import timezone
from .forms import PostForm, CommentsForm
from  django.contrib.auth.decorators import user_passes_test
# Create your views here.


def home(request):
    return render (request, 'blogapp/home.html')

def blog_list(request):
    post = Post.objects.order_by('-published_date')
    context = {
        'posts':post
    }
    return render(request, 'blogapp/blog_list.html', context)

def blog_detail(request, pk=None):
    detail = Post.objects.get(pk=pk)
    context = {
        'detail': detail
    }
    return render(request, 'blogapp/blog_detail.html', context)


def add_post(request, pk=None):

    if request.method == "POST":
        form = PostForm(request.POST)
        if form.is_valid:
            body = form.save(commit=False)
            body.published_date = timezone.now()
            body.save()
            return redirect('blog_list')
        form = PostForm()
    else:
        form = PostForm()

    context = {
        'form': form
    }
    return render(request, 'blogapp/add_post.html', context)

def add_comments(request, pk=None):
    if request.method == "POST":
        form = CommentsForm(request.POST)
        if form.is_valid:
            comment = form.save(commit=False)
            comment.date_added = timezone.now()
            comment.save()
            return redirect('blog_detail')
        form = CommentsForm()
    else:
        form = CommentsForm()

    context = {
        'form': form
    }
    return render(request, 'blogapp/add_comments.html', context)

Answer 1

in your template you use {% for comment in post.comments.all %} but in template context there is no post variable you should use {% for comment in detail.comments.all %}
