Django - Passing ID into url template tag using Javascript

Question

How do I insert an id inside a url template tag using javascript? I tried this way and I did not get it. Can not find the route in the urls.py.

function Edit(pk){
    window.location.assign("{% url 'authentication:edit_user' "+${pk}+" %}");
}
<!-- Other way -->
function Edit(pk){
    window.location.assign("{% url 'authentication:edit_user' "+pk+" %}");
}

Error is:

Reverse for 'edit_user' with arguments '('+${pk}+',)' not found. 1 pattern(s) tried: ['authentication\/user\/edit\/(?P[0-9]+)\/$']

This can't possibly work. Template tags are evaluated server-side, well before the client-side Javascript can run.

You don't need to concatinate the string. The url tag takes parameter. So you can change your code to

window.location.assign("{% url 'authentication:edit_user' pk %}");

Reference - url tag

Thanks for answering. If I do not concatenate this error appears and not find the route. Reverse for 'edit_user' with arguments '('',)' not found. 1 pattern(s) tried: ['authentication\\/user\\/edit\\/(?P<pk>[0-9]+)\\/$']

@DevPython, That error indicates the pk field is empty. You may not be passing it to template properly.
