This is a work for a template tag and specifically for this case
("include with paramteres") there is a helper inclusion_tag.
In a template tags library (file app_dir/templatetags/app_name.py):
from django import template
register=template.Library()
@register.inclusion_tag('product.html')
def product(arg):
return {'product':arg}
Decorator @register.inclusion_tag takes template name for inclusion (it
should be without ".html" if you don't use latest magic-removal).
Function name will become a name of the tag. It accepts one argument and
returns it in a context dictionary for the included template.
You use it then like this:
{% product bestOffer %}
... and bestOffer will be passed in product.html by the name 'product'.
