How to display comments and it's replies in django templates? - django

Question

I want to display comment and it's replies in the template. But there is an issue, every reply may have some other replies. The below snippet is my Comment and CommentReply model:
class Comment(models.Model):
author = models.ForeignKey(Profile, related_name="c_sender", on_delete=models.CASCADE, unique=False)
comment = models.CharField(max_length=500, unique=False)
created_date = models.DateTimeField(auto_now_add=True)
edited_date = models.DateTimeField(blank=True, null=True)
def __str__(self):
return self.comment
#property
def replys(self):
return CommentReply.objects.filter(comment_id=self)
class CommentReply(models.Model):
comment_id = models.ForeignKey(Comment, related_name='sender', on_delete=models.CASCADE)
reply_id = models.ForeignKey(Comment, related_name='reply', on_delete=models.CASCADE)
Updated:
Also I have a model for WorksComments that every comments that related to Work model saved there.
class WorkComment(models.Model):
work_id = models.ForeignKey(Work, on_delete=models.CASCADE, related_name='e_exercise', unique=False)
comment_id = models.ForeignKey(Comment, related_name='e_comment', unique=False)
The below snippet is my view:
comments = WorkComment.objects.filter(work_id=work).all()
return render(request, 'work.html', {'comments': comments})
My question is how to display comments and it's replies under it, and every reply may have some other replyies that I want to display them too.

First things first... put this in your bookmarks; https://ccbv.co.uk/
You're going to want a Detail View here I suspect in order to display the details of an instance.
Setup URLs...
from django.conf.urls import url
from work.views import WorkDetailView
urlpatterns = [
url(r'^(?P<id>[-\d]+)/$', WorkDetailView.as_view(), name='work-detail'),
]
And a view;
from django.views.generic.detail import DetailView
from django.utils import timezone
from work.models import Work
class WorkDetailView(DetailView):
model = Work
def get_context_data(self, **kwargs):
context = super(WorkDetailView, self).get_context_data(**kwargs)
context['comments'] = WorkComment.objects.filter(work_id=self.object.id).all()
return context
Then a simple view might be work/work_detail.html:
<h1>{{ object.title }}</h1>
<p>{{ object.content }}</p>
<h2>Comments</h2>
{% for comment in comments %}
{{ comment }}
{% endfor %}
