Django MPTT - breadcrumb in view function

[enemybass]

How to create breadcrumb in my view function?

    class Category(MPTTModel):
        name = models.CharField(max_length=50, verbose_name=u'Name')
        parent = TreeForeignKey('self', null=True, blank=True, 
related_name='children')
        slug = models.SlugField()

    class Product(models.Model):
        name = models.CharField(max_length=50, verbose_name=u'Name')
        slug = models.SlugField()
        category = models.ManyToManyField(Category, 
verbose_name=u'Category')

    #views
    def post_content(request, product_id):
        product = get_object_or_404(Product, id = product_id)
        return render_to_response('product_info.html', 
{'product':product},context_instance=RequestContext(request))

product_info.html

{{ product.name }}


I want in my single post info (`post_content`) breadcrumb with category.
Something like this:  Category > Subcategory > Sub-Subcategory .,,,

Someone told me to use *get_ancestors:*
*
*
*Example:*
*
*
{% for parent in category.get_ancestors %}
  <a href="{{ parent }}">{{ parent.name }}</a> &gt;
{% endfor %}
{{ category.name }}

How to implement this with my model?

Thank you. I would be grateful.
