Re: Random string template tag
Or you could do {{ "class1,class2,class3,class4"|split:","|random }}
(you'd need to make the |split filter too, Django only comes with |
join)

What do you mean? You pass a context to the template renderer; if the
template you render references a base template, then it will get the
same contexts that the renderer was given.
If you want to hardcode the availability of the 'classes' variable in
every context (so you don't have to remember to define it every time),
you could write a context processor. See
django.core.context_processors for examples.

One option is to use the 'random' filter; your context would need to
define the list of possible strings:
Context({
'classes': ['class1','class2','class3','class4']
})
but then your template could use:
{{ classes|random }}

Something like... > > Sounds like you want to make a custom template tag that uses random.choice() to make the choice for you. I haven't tested the code below, but it's a starting point for what you describe: from random import choice from django import template from django.template import resolve_variable class RandomChoiceNode(template.Node): def __init__(self, *choices): self.choices = choices def render(self, context): try: which = choice(self.choices) result = resolve_variable(which, context) return result except template.VariableDoesNotExist: return '' http://www.djangoproject.com/documentation/templates_python/#passing-template-variables-to-the-tag Fiddle accordingly. -tim --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Random string template tag
I don't know if this exists or not, but I'd like to insert a tag (much like cycle) that allows the random selection of a string. I'm trying to randomly assign a class to a to simulate "random image rotator" type functionality. Something like...
