Hi, just wrapping my head around django, and trying to write an ecommerce
store, when trying to pull out all products belonging to a category getting
such an error

Here are my URL patterns
url(r'^(?P<category_slug>[-\w]+)/$', views.category, name =
'category_detail' ),
url(r'^(?P<category_slug>[-\w]+)/(?P<product_slug>[-\w]+)/$',
views.product, 'catalog_product', name = 'product_detail'),
Here are the corresponding views
def category(request, category_slug):
category_list = Category.objects.filter(category_is_active = True)
c = get_object_or_404(Category, category_slug = category_slug)
products = c.product_set.all()
page_title = c.category_name
meta_keywords = c.category_meta_keywords
meta_description = c.category_meta_description
return render(request, 'categories/category.html', locals())
def product(request, product_slug):
category_list = Category.objects.filter(category_is_active = True)
p = get_object_or_404(Product, product_slug = product_slug)
categories = p.product_categories.all()
page_title = p.product_name
meta_keywords = p.product_meta_keywords
meta_description = p.product_meta_description
# need to evaluate the HTTP method
if request.method == 'POST':
# add to cart... create the bound form
postdata = request.POST.copy()
form = ProductAddToCartForm(request, postdata)
# check if posted data is valid
if form.is_valid():
# add to cart and redirect to cart page
cart.add_to_cart(request)
# if test cookie worked, get rid of it
if request.session.test_cookie_worked():
request.session.delete_test_cookie()
url = urlresolvers.reverse('show_cart')
return HttpResponseRedirect(url)
else:
# it's a GET, create the unbound form. Note request as a kwarg
form = ProductAddToCartForm(request = request, label_suffix = ':')
# assign the hidden input the product slug
form.fields['product_slug'].widget.attrs['value'] = product_slug
# set the test cookie on our first GET request
request.session.set_test_cookie()
return render(request, 'products/product.html', locals())
and here is the part of the corresponding view
{% for p in products %}
<div class = "product_thumbnail">
<a href = "{{ p.get_absolute_url }}">
<img src = "{{ MEDIA_URL }}/catalog/products/thumbnails/{{
p.product_image }}" alt = "{{ p.product_name }}" class = "bn" />
<br/>
{{ p.product_name }}
</a>
</div>
{% endfor %}
Thanx in advance )
