Based on the rest of your template from the github link, looks like:
{% url 'nowandthen:add_comment' image.id %}
...should instead be:
{% url 'nowandthen:add_comment' p.image.id %}

I am putting together a website which has a photo gallery where users can add
comments. When I go to the photo gallery page, I get the following error
message:
NoReverseMatch at /photo_feed/ Reverse for 'add_comment' with arguments '('',)'
not found. 1 pattern(s) tried: ['add_comment/$']
The code for the relevant part of the HTML document is as follows:
<h2>comments</h2>
{% if not comments %}
No comments
{% endif %}
{% for x in comment %}
<div class="comments" style="padding: 10px;">
<p class="font-weight-bold">
<h4>Comment by</h4> {{ x.user }}
<span class=" text-muted font-weight-normal">
{{ x.created_on }}
</span>
</p>
{{ x.body | linebreaks }}
</div>
{% endfor %}
</div>
<div class="card-body">
{% if new_comment %}
<h2>Your comment has been posted.</h2>
{% else %}
<h3>Leave a comment</h3>
<form action="{% url 'nowandthen:add_comment' image.id %}"
method="POST">
{{ comment_form.as_p }}
{% csrf_token %}
<button type="submit" class="btn btn-primary
btn-lg">Submit</button>
{% endif %}
The URLs.py entry for add_comment is path('add_comment/<int: image_id>',
views.add_comment, name='add_comment'). Removing the int: image_id doesn't fix the
problem.
When I go into admin, no ids appear to have been generated for the photos.
Could it be that the problem is that there are missing IDs? If so, how do I fix
this?
The repository URL is https://github.com/EmilyQuimby/my_now_and_then.
Thank you.
