Django's pluralize template filter
Django tip:
Sometimes you need to use the single or plural form based on the number you're displaying. You can handle this by using the pluralize filter.
{{ number_of_friends }} friend{{ number_of_friends|pluralize }} # 1 friend # 2 friends
An "s" is automatically used as the suffix, but you can also provide your own suffix (for both singular and plural versions).
{{ number_of_mice }} {{ number_of_mice|pluralize:"mouse,mice" }} # 1 mouse # 2 mice
