Random string in Django template

Is there any way to have a random string in a Django template?

I would like to have multiple strings displaying randomly like:

{% here generate random number rnd ?%}

{% if rnd == 1 %}
  {% trans "hello my name is john" %}
{% endif %}

{% if rnd == 2 %}
  {% trans "hello my name is bill" %}
{% endif %}

EDIT:
Thanks for answer but my case needed something more specific as it was in the base template (which I forgot to mention sorry ). So after crawling Google and some docs I fall on context processor article which did the job, I found it a little bit "heavy" anyway just for generating a random number...

here is the blog page : http://www.b-list.org/weblog/2006/jun/14/django-tips-template-context-processors/

Template tag did not the trick (or I did not find how) as it return a tag that cannot be translated as I remember (see blocktrans doc)

I did not find a way to generate a number for the base view (is there any?) and if there is a way better than context process I'd be glad to have some info.

Solution

  • I guess you want to have a tag that generates random strings from some table containing strings. See this Django snippet:

    http://djangosnippets.org/snippets/286/:

    # model
class Quote(models.Model):
  quote = models.TextField(help_text="Enter the quote")
  by = models.CharField(maxlength=30, help_text="Enter the quote author")
  slug = models.SlugField(prepopulate_from=("by", "quote"), maxlength=25)
  def __str__(self):
    return (self.quote)

# template tag
from django import template
register = template.Library()
from website.quotes.models import Quote

@register.simple_tag
def random_quote():
  """
  Returns a random quote
  """
  quote = Quote.objects.order_by('?')[0]

  return str(quote)
