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, It always 0 items. Please help me to show where I was wrong. Thank you a lot. ~ Ton Dong - Models: 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, ) - Controller/default.py def index(): session.cart = session.cart products = db(db.product).select(orderby=db.product.sortable) return locals() def user(): return dict(form=auth()) def download(): return response.download(request,db) def call(): session.forget() return service() @auth.requires_login() def cart(): return dict(cart=session.cart) @auth.requires_login() def pay(): import uuid invoice = str(uuid.uuid4()) total = sum(db.product(id).price*qty for id, qty in session.cart.items()) form = SQLFORM.factory(Field('creditcard',default='000000000000000'), Field('expiration', default='12/2015'), Field('cvv', default='111'), Field('total','double',default=total,writable=False)) if form.accepts(request,session): if process(form.vars.creditcard, form.vars.expiration, total, form.vars.cvv,0.0,'invoice'): for key, value in sesssion.cart.items(): db.sale.insert(invoice=invoice, buyer=auth.user.id, product=key, quantity = value, price = db.product(key).price, creditcard = form.vars.creditcard) session.cart.clear() session.flash = 'Thanks for your order' redirect(URL('index')) return dict(cart=session.cart, form=form) def cart_callback(): id = int(request.vars.id) if request.vars.action == 'add': session.cart[id] = int(session.cart.get(id,0))+1 if request.vars.action == 'sub': session.cart[id] = max(0,session.cart.get(id,0)-1) return str(session.cart[id]) - Views/index.html {{extend 'layout.html'}} {{for p in products:}} <div> <h5> {{=p.nameproduct}} - ${{=p.price}} </h5> <br> <img width="200px" src="{{=URL <http://127.0.0.1:8000/examples/global/vars/URL>('download', args=p.image)}}" /> <br> <span id='item{{=p.id}}'>{{=session <http://127.0.0.1:8000/examples/global/vars/session>.cart.get(p.id,0)}}</span> in cart <button onclick='ajax('{{=URL <http://127.0.0.1:8000/examples/global/vars/URL>('cart_callback', vars=dict(id=p.id,action='add'))}}',[],'item{{=p.id}}')'>add </button> </div> {{pass}} --
