Question

is there a way to use a .js variable as a parameter in a Django template url reverse call? The approach below does not work, which is not very surprising:

"fnRender": function ( o, val ) {
     return '<a href="{% url update_task o.aData[0] %}">' + o.aData[1]  +'</a>';
}

I know that I could pass the needed data via the Django view, but unfortunately I have to use the data from the .js library.

What I usually do is pass some sort of default parameter into the URL in the template, which acts as a sentinel which I can then replace dynamically in the Javascript. Something like:

var url = '{% url update_task "foobarbaz" %}';
url = url.replace('foobarbaz', o.aData[0]);
return '<a href="' + url + '">' + o.aData[1]  +'</a>';
