notice that
productId = request.vars.productId
userId = session.auth.user.id
sql = "INSERT INTO orders (productId, userId, qty, order_date) values
(str(productId), str(userId), str(qty), str(order_date))"
#sql = sql + "(" + str(productId) + "," + str(userId) + "," + str(qty)
+ "," + str(order_date) + "')"
r = db.executesql(sql)
with this model:
db.define_table('orders',
Field('productId', db.product),
Field('userId', db.auth_user),
Field('qty', 'float'),
Field('order_date','datetime'),
)
in PYDAL becomes:
db.orders.insert(productId=productId, userId=auth.user_id, qty=qty,
order_date=request.now)
