Web.py待办事项列表示例，但内存中有数据库

Question

First of all I must say I am a complete newbie to web.py .

I want to modify the todo list example to use a database in memory instead of using mysql. I ended up writing:

import web

db = web.database(dbn="sqlite", db=":memory:")

db.query("CREATE TABLE todo (id INT AUTO_INCREMENT, title TEXT);")



def get_todos():

    return db.select('todo', order='id')

def new_todo(text):

    db.insert('todo', title=text)

def del_todo(id):

    db.delete('todo', where="id=$id", vars=locals())

But when I open the website I get:

<class 'sqlite3.OperationalError'> at /
no such table: todo

Any idea?

I think it won't work by design, because webpy rerun all the program for each http request. So after at the second request, another database will be created so no persistence betwwen http requests.
