Showing user's comments on posts in Django - django

Question

I am adding a comment section for my posts in a blog, I reached to the part where I can add new comments and get it saved in the db and I can view them in the admin, but I am stuck to showing the username and the comment in the comment section, I have to go the admin and choose the name of the user and the blog name to appear in the page, how do i link them together
Here is the Models.py
class Comment(models.Model):
post = models.ForeignKey(Post, on_delete=models.CASCADE, null=True, blank=True)
user = models.ForeignKey(User, on_delete=models.CASCADE, null=True, blank=True)
content = models.TextField(max_length=160)
timestamp = models.DateTimeField(auto_now_add=True)
def __str__(self):
return self.content
Here is the views.py:
class PostDetailView(DetailView):
model = Post
template_name = "post_detail.html"
def get_context_data(self, *args, **kwargs):
context = super(PostDetailView, self).get_context_data()
post = get_object_or_404(Post, slug=self.kwargs['slug'])
comments = Comment.objects.filter(post=post).order_by('-id')
total_likes = post.total_likes()
liked = False
if post.likes.filter(id=self.request.user.id).exists():
liked = True
if self.request.method == 'POST':
comment_form = CommentForm(self.request.POST or None)
if comment_form.is_valid():
content = self.request.POST.get('content')
comment = Comment.objects.create(
post=post, user=request.user, content=content)
comment.save()
return HttpResponseRedirect("post_detail.html")
else:
comment_form = CommentForm()
context["total_likes"] = total_likes
context["liked"] = liked
context["comments"] = comments
context["comment_form"] = comment_form
return context
class PostCommentCreateView(LoginRequiredMixin, CreateView):
model = Comment
fields = ['content', ]
success_url = reverse_lazy('score:post-detail')
def post(self, request, *args, **kwargs):
form = CommentForm(request.POST)
if form.is_valid():
post = form.save()
post.save()
print(args, kwargs, request.POST)
return redirect('score:post-detail', slug=kwargs['slug'])
here is the template
<form action={% url 'score:post-comment' post.slug %} method="post" class="comment-form" action=".">
{% comment %} <form method="post" class="comment-form" action="."> {% endcomment %}
{% csrf_token %}
{{ comment_form.as_p }}
{% if request.user.is_authenticated %}
<input type="submit" value="Submit" class="btn btn-outline-success">
{% else %}
<input type="submit" value="Submit" class="btn btn-outline-success" disabled> You must be Logged in to Comment
{% endif %}
</form>
here is the form
class CommentForm(forms.ModelForm):
content = forms.CharField(label="", widget=forms.Textarea(
attrs={'class': 'form-control', 'placeholder': 'Text goes here!!!', 'rows': '4', 'cols': '50'}))
class Meta:
model = Comment
fields = ('content',)

A CreateView is defined to remove most of the boilplate code, so you should not reimplement that in the post method, but let the CreateView do its work.
What you here should do is override the .form_valid(…) method [Django-doc] and the .form_invalid(…) method [Django-doc], and the .get_success_url(…) method [Django-doc] to redirect to the proper view:
from django.http import HttpResponseRedirect
from django.shortcuts import get_object_or_404
from django.urls import reverse
class PostCommentCreateView(LoginRequiredMixin, CreateView):
model = Comment
form_class = CommentForm
def form_valid(self, form):
post = get_object_or_404(Post, slug=self.kwargs['slug'])
form.instance.user = self.request.user
form.instance.post = post
return super().form_valid(form)
def form_invalid(self, form):
return HttpResponseRedirect(self.get_success_url())
def get_success_url(self):
return reverse('score:post-detail', kwargs=dict(slug=self.kwargs['slug']))
