Edit: The issue isn't related to pluralize. See comment.
How do I make pluralize to display 0? In the database are 2 book listings ('books'), 6 physical copies ('book_instances'), and 0 available for borrowing ('bookinstance_available'). In the code below, the first two display correctly: 2 and 6. The third line should display 0, but nothing appears. Is there anything I need to do for it to show 0 without writing special code (which seems to be the case when I searched)?
There are {{ num_books }} book{{ num_books|pluralize }} in the library catalog. <br>
There are {{num_bookinstance}} book{{num_bookinstance|pluralize}} in the collection. <br>
There are {{num_bookinstance_available}} book{{num_bookinstance_available|pluralize}} available for borrowing.
By the way, I'm working through the Mozilla Django tutorial.
