Hi all,
I am a newbie in web design. I followed the instructions in the video
"Build an online store with web2py" at http://vimeo.com/20768689
I don't know why I can not add any items to cart. Please help me to show
where I was wrong. Thank you a lot.

The code:
- Model: hmw.py
# coding: utf8
db.define_table(
'product',
Field('nameproduct', 'string',notnull=True,unique=True, length=30),
Field('price', 'double'),
Field('desciption', 'text'),
Field('image','upload'),
Field('sortable','integer'),
auth.signature,
format = '%(nameproduct)s',
singular = 'product',
plural = 'products',
)
db.define_table(
'sale',
Field('invoice'),
Field('creditcard'),
Field('buyer',db.auth_user),
Field('product',db.product),
Field('quantity','integer'),
Field('price', 'double'),
Field('shipped', 'boolean', default=False),
auth.signature,
)
