Re: NoReverseMatch error message - Please help
Sometimes the error can be from your url.py or even views.py and also make
sure no typo. Check each on e of the above carefully. Hopefully you might
see the bug.
Cheers

Re: NoReverseMatch error message - Please help
Thanks Ryan.
I've just tried that, but I still get an error message.
By the way, is it definitely .id and not _id? I've seen both, and Django docs
says: 'Behind the scenes, Django appends "_id" to the field name to create its
database column name, which makes me wonder if it might be _id.
Incidentally, I've also tried amending the relevant URL path to
path('add_comment/', views.add_comment, name='add_comment') -
with underscore and with a dot before the id - but that doesn't work.

Re: NoReverseMatch error message - Please help
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 %}

The code for the relevant part of the HTML document is as follows:

No comments

{% for x in comment %}
Comment by {{ x.user }}

{{ x.body | linebreaks }}

The URLs.py entry for add_comment is path('add_comment/',
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?

Trailing slashes are part of the path, so "/foobar/" is not the same as
"/foobar".
Hopefully that should give you a hint to what is most likely the cause
of your problem.
Kind regards,
