This is what I have in my please_wait.html
<script type="text/javascript"
src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js";>
$.getJSON('{% url run_DHM %}')
});
</script>
This is the django error
Caught NoReverseMatch while rendering: Reverse for 'run_DHM' with
arguments '()' and keyword arguments '{}' not found.
run_DHM takes 'request' as an argument. How do I pass it the argument??
