How to loop X times in Django?

Question

I have user reviews on my site. Each review has a rating of 1-5 stars. I want to print that many stars. How do I do it? I only see {% for X in Y %} which lets you iterate over a list, but not a certain number of times.

Answer 1

Use the Template range filter by zalun:

from django.template import Library

register = Library()

@register.filter
def get_range( value ):
  """
    Filter - returns a list containing range made from given value
    Usage (in template):

    <ul>{% for i in 3|get_range %}
      <li>{{ i }}. Do something</li>
    {% endfor %}</ul>

    Results with the HTML:
    <ul>
      <li>0. Do something</li>
      <li>1. Do something</li>
      <li>2. Do something</li>
    </ul>

    Instead of 3 one may use the variable set in the views
  """
  return range( value )

Answer 2

No need for a custom filter - make_list will do the job:

{% for i in '123'|make_list %}
