so in your tempalte it will be parent:parent:bob thomas.
usualy i use locals() to pass all the var to template.
return render_to_repsonse(template,
locals(),context_instance=RequestContext(request))
don't know if this is best practice in django, but make me easier to work
with variables need to pass to template without have to include it in an
array.
with the locals() you will have the data in your template like you mention
below.
