HTML code not being read

[Jeff Waters]

Hi

I have written some code that allows users of a website to comment on photos in a picture gallery, using a form. However, when I test the code, no comments are displayed.

It would appear that Django is not processing the following code (from my HTML file for the photo gallery), given that 'Comment by' is not displayed on screen:

{% for comment in comments %}
<div class="comments" style="padding: 10px;">
<p class="font-weight-bold">
<h4>Comment by</h4> {{ comment.user }}
<span class=" text-muted font-weight-normal">
{{ comment.created_on }}
</span>
</p>
{{ comment.body | linebreaks }}
</div>
{% endfor %}

Does anyone have any suggestions as to how I can fix this, please?

Thank you.

Jeff

The problem might not be from the HTML template but the View.

All the HTML elements within your for loop will not display if there are no records to loop through in "comments"

Have you all ready use a content that define your content

[Jeff Waters]

Hi

Thanks for getting back to me.

This is from my views.py:

@login_required
def add_comment(request, image_id):
new_comment = None
template_name = 'add_comment.html'
image = get_object_or_404(Picture, id=image_id)
comment = image.comment.filter(active=True)
new_comment = None
# Comment posted
if request.method == 'POST':
comment_form = CommentForm(data=request.POST)
if comment_form.is_valid():
# Create Comment object and don't save to database yet
new_comment = comment_form.save(commit=False)
# Assign the current post to the comment
new_comment.post = post
# Save the comment to the database
new_comment.save()
else:
comment_form = CommentForm()

context = {'comment_form': comment_form, 'image': image,'comment': comment, 'new_comment': new_comment,'comment_form': comment_form}

return render(request, template_name, context)

Does that look correct to you?

Hi

I'm not sure what you mean by 'Have you all ready use a content that define your content'.

I'm new to Django, so am not familiar with all of the terminology yet.

Can you elaborate please?

Thanks

Jeff

Your view context uses 'comment'(singular), while your template uses
'comments'(plural).  I'd chnage your view context to match the template.

[Luqman Shofuleji]

What you passed to the context in your views.py is 'comment', but you are looping through 'comments' in the template

Thanks guys

I previously had 'comments' in the plural in views.py, but had the same problem.

Am I right in thinking that Django recognises that 'comments' is the plural of 'comment', so if it knows from the view what a comment is, it knows what comments are?

Thanks,

Jeff

show me your views 

[Jeff Waters]

I've modified my code a bit to try (unsuccessfully!) to get this working.

My views.py is now as follows:

@login_required
def add_comment(request, image_id):
new_comment = None
template_name = 'add_comment.html'
image = get_object_or_404(Picture, id=image_id)

comment = image.comments.filter(active=True)

new_comment = None
# Comment posted
if request.method == 'POST':

comment_form = CommentForm(request.POST)

if comment_form.is_valid():
# Create Comment object and don't save to database yet
new_comment = comment_form.save(commit=False)
# Assign the current post to the comment
new_comment.post = post
# Save the comment to the database
new_comment.save()
else:
comment_form = CommentForm()

context = {'image': image,'comment': comment, 'new_comment': new_comment,'comment_form': comment_form}

return render(request, template_name, context)

My html code for the gallery is now:

<h2>comments</h2>
{% if not comments %}
No comments
{% endif %}
{% for comment in comment %}

<div class="comments" style="padding: 10px;">
<p class="font-weight-bold">
<h4>Comment by</h4> {{ comment.user }}
<span class=" text-muted font-weight-normal">
{{ comment.created_on }}
</span>
</p>
{{ comment.body | linebreaks }}
</div>
{% endfor %}

The problem I now have is that I now get the following error message: Reverse for 'add_comment' with arguments '('',)' not found. 1 pattern(s) tried: ['add_comment/(?P<image_id>[0-9]+)$']

Any suggestions would be much appreciated.

Thanks

Jeff

Did you connect your template folder on settings.py ?
