How to pass a url parameter to the url tag in a template

Question

I am using Django 3.1

I have URLs configured so that I can corretly use the following in my template:

<li><a href="{% url 'sitemember:profile' 'bobby' %}">{{ user.username }}&nbsp;&nbsp;</a></li>

Where user.username resolves to 'bobby'

How do I pass the variable user.username to the url() tag, so that the URL resolves correctly as:

https://localhost:/user/bobby (as an example)

I get: `Reverse for 'profile' with arguments '('',)' not found. 1 pattern(s) tried: ['user\\/(?P[^/]+)\\/$'] ` – Homunculus Reticulli Oct 28 '20 at 22:40
@HomunculusReticulli: that is because the `username` is empty, or `user` does not exists in the template. This is what the error is about it says *arguments `('',)`*, so it has one parameter, but that resolved to the empty string. – Willem Van Onsem Oct 28 '20 at 22:41
Oh, I see. Thanks very much. That makes sense. The error message was a bit cryptic, but yes, it makes sense now that you explained it. – Homunculus Reticulli Oct 28 '20 at 22:42
