already try your reccomendation, but still got error.

and i check with other view in the apps, i found out you are right, the bug
is in the render_to_response.

i fix it with this one :
  return render_to_response(template_name,
locals(),context_instance=RequestContext(request))

i miss the RequestContext(request))

This one think which pass all the context processed variable to the
template.

Thanks, and i learn now how to read error message and track it down now..

It solved now..

continue to learning...

The bug is in this line. render_to_response() takes a dictionary as the
context_instance, but this code just passes the request instance.

You probably meant either:

return render_to_response(template_name, locals(),
context_instance=(request, ))  # Note comma

or

return render_to_response(template_name, locals(),
context_instance={'request':request}))

HTH,

Malcolm

Hi Shawn,

Here are the view called :

# Create your views here.
from django.shortcuts import render_to_response
from django.template import RequestContext
from ecomstore.cart import cart

def show_cart(request, template_name="cart/cart.html"):
if request.method == 'POST':
postdata = request.POST.copy()
if postdata['submit'] == 'Remove':
cart.remove_from_cart(request)
if postdata['submit'] == 'Update':
cart.update_cart(request)

cart_item_count = cart.cart_item_count(request)
page_title = "Shopping Cart"
cart_subtotal = cart.cart_subtotal(request)
return render_to_response(template_name, locals(),
context_instance=(request))

Thanks for your help..

May we see the rest of your view? If not, you'll have to figure it out 
by examining exactly what your 'request' variable contains. The error is 
clearly from calling update() on it, and it not being allowed.
