Why? You don't show your models, which would have been useful, but 
presumably there's a ForeignKey from Task to Tasklist. So instead of 
passing the tasklist ID to the child template, just pass the actual 
tasklist object, then you can refer to the tasks via the reverse 
relationship: {{ tasklist.task_set.all }}
