django custom template tags: render method not called

payment-tags.py

@register.simple_tag
def has_purchased(user_id):
  payments = Payment.objects.all(user__id=user_id)
  return PaymentObjects(payments)

class PaymentObjects(template.Node):
  def __init__(self, payments):
    print 'inside init'
    self.payments_obj = payments

  def render(self, context):
    print 'inside render'
    context['payments'] = self.payments_obj
    return ''

Indside html:

{% load payment-tags %}
{% has_purchased request.user.id %}

The render method of PaymentObjects class never get called, It goes inside the init function but not inside render..

I had searched this issue on google but didn't got any satisfactory answer which can solve the issue.

Any advice would be greatly appreciated, Thanks.

register.simple_tag is used for tag functions that immediately return the result (Django creates the node for you). If you want to return your own node, use register.tag instead.
