This is getting way too many votes for what amounts to bad advice. I think you should keep subview rendering methods out of your templates (i.e. keep your templates "dumb"). You can just create placeholder elements in the template, and then pass the placeholder element to the subview constructor. Or you can just append a list of collection-based subviews to a single container element.

You should be able to write Backbone apps without resorting to stuff like $("#row_#{@model.id}")
