Make a macro for the AJAX update module This is less repetitive than typing out the HTML with all its attributes every time. It also lets us wrap up the idea of ‘finished’ as a parameter, so the AJAX code will only be initiated when it’s needed, eg if a job is still processing. 2016-06-28 09:21:46 +01:00			`{% macro ajax_block(url, key, interval=2, finished=False) %}`
