comment not being submitted by my django form - django

Question

I want my users to be able to add comments under a transfernews [I am creating a sports related website], I tried this code, but for some reason I am getting this error TypeError at /transfernews/ Field 'id' expected a number but got <Transfernews: Transfernews object (3)>., I can add comments manually from the admin page but can't from the comment form. Can anyone please tell me how to fix my code?
My models.py:
class Transfernews(models.Model):
player_name = models.CharField(max_length=255)
player_image = models.CharField(max_length=2083)
player_description = models.CharField(max_length=3000)
date_posted = models.DateTimeField(default=timezone.now)
class Comment(models.Model):
user = models.ForeignKey(to=User, on_delete=models.CASCADE)
transfernews = models.ForeignKey(Transfernews, related_name="comments", on_delete=models.CASCADE)
body = models.TextField()
date_added = models.DateTimeField(auto_now_add=True)
def __str__(self):
return '%s - %s' % (self.transfernews.player_name, self.user.username)
My forms.py:
class CommentForm(forms.ModelForm):
class Meta:
model = Comment
fields = ('body',)
My views.py:
def transfer_targets(request):
transfernews = Transfernews.objects.all()
news = request.POST.get("transfer_id", None)
form = CommentForm(request.POST or None)
if form.is_valid():
new_comment = form.save(commit=False)
new_comment.user = User.objects.get(id=request.user.id)
new_comment.transfernews_id = Transfernews.objects.get(id=news)
new_comment.save()
return redirect(request.path_info)
return render(request, 'transfernews.html', {'transfernews': transfernews, 'form': form})
My html file:
{% for transfer in transfernews %}
<h2>Comments...</h2>
{% if not transfer.comments.all %}
No comments Yet...
{% else %}
{% for comment in transfer.comments.all %}
<strong>
{{ comment.user.username }} - {{ comment.date_added }}
</strong>
<br/>
{{ comment.body }}
<br/><br/>
{% endfor %}
{% endif %}
<hr>
<div>Comment and let us know your thoughts</div>
<form method="POST">
{% csrf_token %}
<input type="hidden" value="{{ transfer.id}}">
<div class="bg-alert p-2">
<div class="d-flex flex-row align-items-start">
</div>
<div class="mt-2 text-right">
{{ form|crispy }}
<br>
<button class="btn btn-primary btn-sm shadow-none" type="submit">Post comment</button>
<button class="btn btn-outline-primary btn-sm ml-1 shadow-none" type="button">Cancel</button>
</div>
</div>
</form>
{% endfor %}

Answer 1

Try using new_comment.transfernews = transfernews instead of new_comment.transfernews_id = transfernews.id.
Also change redirect(request.path_info) to redirect(reverse('<app_name>:<url_namespace>')).

Answer 2

You have to add a name attribute to your hidden input, then only the hidden input data will be included in the form data.
<input type="hidden" name="transfer_id" value="{{ transfer.id}}">
and in your transfer_targets view make these changes
def transfer_targets(request):
transfernews = Transfernews.objects.all()
transfernews = request.POST.get("transfer_id", None)
form = CommentForm(request.POST or None)
if form.is_valid():
new_comment = form.save(commit=False)
new_comment.user = User.objects.get(id=request.user.id)
new_comment.transfernews_id = transfernews.id
new_comment.transfernews_id = Transfernews.objects.get(id=transfernews)
new_comment.save()
return redirect(request.path_info)
return render(request, 'transfernews.html', {'transfernews': transfernews, 'form': form})
