Question

I have an integer value being passed to my template, and I want to create a number of html elements equal to that integer.

game.players is a number 0-10.

I want to create a number of input elements equal to the count of game.players.

Answer 1

Either populate the context with an iterable or define a template filter that handles a number input and outputs an iterable.

Note: it’s recommended to define the iterable in your view as that’s the django philosophy and why there’s no built in range filter.

Here’s what a core dev thinks:

My impression of this idea is that it
is trying to lead to programming in
the template. If you have a list of
options that need to be rendered, they
should be computed in the view, not in
the template. If that’s as simple as a
range of values, then so be it.

# view
for game in games:
    game.players_range = range(game.players)

return render_to_response("foo.html", {'games': games})


# template
{% for game in games %}
    {% for i in game.players_range %}
      Element {{ i }}
    {% endfor %}
{% endfor %}
