Want to access blog post title on comment form page

Hi, happy new year!

I'm trying to put the Django Girls comments functionality onto my blog, which I've copied from another tutorial elsewhere. It's going pretty well, but I want to be able to put the post title into the comment form page (it's a separate page in this tutorial, I'd rather it was on the same page as the blog post but that's a bit tricky for me at this point).

This is as far as I've got:

The add_comment_to_post view:

def add_comment_to_post(request, pk):
post = get_object_or_404(Post, pk=pk)

def post_name(self, obj):
    return obj.post.title

if request.method == "POST":
    form = CommentForm(request.POST)
    if form.is_valid():
        comment = form.save(commit=False)
        comment.post = post
        comment.save()
        return redirect('/' + post.slug)
else:
    form = CommentForm()
return render(request, 'blog/add_comment_to_post.html', {'form': form})

And here's the template:

{% extends 'base.html' %}

{% block content %}
<h1>New comment on {{ post_name }}</h1>
<form method="POST" class="post-form">{% csrf_token %}
    {{ form.as_p }}
    <button type="submit" class="save btn btn-default">Send</button>
</form>
{% endblock %}

Am I close?

HI there, how about adding the post object as an extra variable to the context dictionary, in the render command?

Brilliant, thanks! That worked. My code now looks like this:

def add_comment_to_post(request, pk):
post = get_object_or_404(Post, pk=pk)

if request.method == "POST":
    form = CommentForm(request.POST)
    if form.is_valid():
        comment = form.save(commit=False)
        comment.post = post
        comment.save()
        return redirect('/' + post.slug)
else:
    form = CommentForm()
return render(request, 'blog/add_comment_to_post.html', dict(form=form, post=post))
