Django snippets: Smart {% if %} template tag. Chris Beaven’s drop-in replacement for Django’s {% if %} tag that adds comparison operators (less than, greater than, not equal etc) while staying backwards compatible with the less able original. I love it. This is one place where I no longer favour Django’s stated philosophy: I think it’s perfectly reasonable to use comparisons in presentation logic, and I’ve found that in my own code the lack of an advanced if tag frequently leads to pure presentation logic sneaking in to my view functions. # 3rd March 2009, 3:03 pm

Django snippets: “for” template tag with support for “else” if array is empty. A neat solution to a common pattern; I’d personally like to see this included in Django proper. # 16th January 2008, 9:42 pm

Most HTML templating languages are written incorrectly. “If you ever find yourself in the position of designing an html template language, please make the default behavior when including variables be to HTML-escape them.” I couldn’t agree more. # 15th April 2007, 8:28 pm
