我在这里遵循教程http://webpy.org/docs/0.3/tutorial然后环顾网络以了解如何使用 sqlite 的待办事项列表部分并找到了这个http://kzar.co.uk/blog /view/web.py-tutorial-sqlite

我无法通过此错误。我已经搜索过,但我找不到的任何结果都对我有太大帮助。大多数人建议将引号从括号中取出。

错误

<type 'exceptions.ValueError'> at /
invalid literal for int() with base 10: '19 02:39:09'

代码.py

import web

render = web.template.render('templates/')

db = web.database(dbn='sqlite', db='testdb')

urls = (
    '/', 'index'
)

app = web.application(urls, globals())

class index:
    def GET(self):
        todos = db.select('todo')
        return render.index(todos)

if __name__ == "__main__": app.run()

模板/index.html

$def with (todos)
<ul>
$for todo in todos:
    <li id="t$todo.id">$todo.title</li>
</ul>

测试

CREATE TABLE todo (id integer primary key, title text, created date, done boolean default 'f');
CREATE TRIGGER insert_todo_created after insert on todo
begin
update todo set created = datetime('now')
where rowid = new.rowid;
end;

web.py sqlite 非常新

在某个地方,int()正在使用参数调用'19 02:39:09'int()不能处理冒号或空格。

>>> int('19 02:39:09')
Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    int('19 02:39:09')
ValueError: invalid literal for int() with base 10: '19 02:39:09'

>>> int(':')
Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    int(':')
ValueError: invalid literal for int() with base 10: ':'

>>> int('19 02 39 09')
Traceback (most recent call last):
  File "<pyshell#2>", line 1, in <module>
    int('19 02 39 09')
ValueError: invalid literal for int() with base 10: '19 02 39 09'

>>> int('19023909')
19023909
>>> 

我建议调用replace()以摆脱这样的空格和冒号:

>>> date='19 02:39:09'
>>> date=date.replace(" ","")
>>> date
'1902:39:09'
>>> date=date.replace(":","")
>>> date
'19023909'
>>> int(date)  ## It works now!
19023909
>>> 

希望这可以帮助。

只需将“创建”列的类型更改为时间戳:

日期格式为“YYYY-MM-DD”

时间戳 - “YYYY-MM-DD HH:MM:SS”

这个 sql 应该可以正常工作:

CREATE TABLE todo (id integer primary key, title text, created timestamp, done boolean default 'f');
CREATE TRIGGER insert_todo_created after insert on todo
begin
update todo set created = datetime('now', 'localtime')
where rowid = new.rowid;
end;
