Django - Comment form - django

Question

I have 4 models: User, Blogger, Post and Comment.
Now, in 'post_desc.html', i want to insert a comment box.
{% if user.is_authenticated %}
<form method="post">
{% csrf_token %}
<input type="text" name="comment" style="width: 800px; height: 145px;"></br></br>
<button type="submit">Submit Comment</button>
</form>
{% else %}
<p>Login to comment</p>
{% endif %}
So, this form will only take comment from the user.
But how to store information like 'commented_by' which will the user that is currently logged in and 'commented_on' which will be the post_topic in which he/she is commenting.
How to store these information automatically? in views.py i tried 'request.user' but that didn't worked. Any solutions?
Comment model:
class Comment(models.Model):
commented_by = models.ForeignKey(User, related_name='comments')
commented_on = models.ForeignKey(Post, related_name='comments')
commented_text = models.CharField(max_length=500)
commented_time = models.DateTimeField(auto_now_add=True)
Post model:
class Post(models.Model):
topic = models.CharField(max_length=200)
description = models.TextField()
created_by = models.ForeignKey(User, related_name='posts')
created_on = models.DateTimeField()
I did this in my view.py
def post_desc(request, pk):
post = get_object_or_404(Post, pk=pk)
if request.method == 'POST':
comment = request.POST['comment']
comments = Comment.objects.create(
commented_text = comment,
commented_on = request.topic,
commented_by = request.user
)
return redirect('post_desc', pk=post.pk)
return render(request, 'post_desc.html', {'post': post})
But it is giving error, "'WSGIRequest' object has no attribute 'post'".

Answer 1

The only thing wrong with your code is that there's no such thing as request.topic. The topic is the Post, which you already have.
comments = Comment.objects.create(
commented_text = comment,
commented_on = post,
commented_by = request.user
)

Answer 2

you have to a create a url that have a pk parameter to know where to post the comment in which post?:
url(r'add/comment/post/(?P<pk>[0-9]+)', views.new_comment, name="comment")
now let's create the view new_comment:
from django.utils import timezone
def new_comment(request, pk):
user = request.user
comment_text = request.POST['your-comment-input-name']
post = Post.objects.get(id=pk)
Comment.objects.create(created_by=user, text=comment_text, post=post, create_at=timezone.localtime(timezone.now()))
return HttpResponseRedirect(request.META.get('HTTP_REFERER'))
don't forget to set your form action to action="{% url 'comment' Post.id %}"

I have something like that in my blog project which I develop for improve myself in django python.
my model;
class Comment(models.Model):
post = models.ForeignKey('post.Post', related_name='comments', on_delete=models.CASCADE)
name = models.CharField(max_length=150, verbose_name='Your Name')
comment = models.TextField(verbose_name='Your Comment')
created_date = models.DateTimeField(auto_now_add=True)
my view for post detail page;
def post_detail(request, slug):
post = get_object_or_404(Post, slug=slug)
form = CommentForm(request.POST or None)
if form.is_valid():
comment = form.save(commit=False)
comment.post = post
comment.save()
return HttpResponseRedirect('your redirect page')
context = {
'post': post,
'form': form,
}
return render(request, 'post/detail.html', context)
my post detail template page;
<h3>Comments;</h3>
{% if post.comments.count <= 0 %}
<h4>No comment yet!</h4>
{% else %}
{% for comment in post.comments.all %}
<h4>{{ comment.name }} |
<small>{{ comment.created_date|timesince }}</small>
</h4>
<p>{{ comment.comment|linebreaks }}</p>
<hr/>
{% endfor %}
{% endif %}
<h3>Add Comment:</h3>
{% include 'post/comment.html' %}
my comment form template;
{% load crispy_forms_tags %}
<form method="post">
{% csrf_token %}
{{ form|crispy }}
<input class="btn btn-primary" type="submit" value="Add Comment"/>
</form>
Hope this helps.
