我在这里按照教程http://webpy.org/docs/0.3/tutorial然后浏览网页以了解如何使用sqlite使用todo列表部分并找到此http://kzar.co.uk/blog/view/web.py-tutorial-sqlite
我无法通过此错误。我搜索过,没有一个我能找到的结果帮助我太多了。大多数人都建议从括号中取出引号。
错误
<type 'exceptions.ValueError'> at /
invalid literal for int() with base 10: '19 02:39:09'
code.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中
$def with (todos)
<ul>
$for todo in todos:
<li id="t$todo.id">$todo.title</li>
</ul>
testbd
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;
非常新的web.py sqlite

在某处,使用参数int()
调用'19 02:39:09'
。 int()
无法处理冒号或空格。
>>> 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()
来摆脱像这样的空格和冒号:
>>> date='19 02:39:09'
>>> date=date.replace(" ","")
>>> date
'1902:39:09'
>>> date=date.replace(":","")
>>> date
'19023909'
>>> int(date) ## It works now!
19023909
>>>
希望这有帮助。

只需将“已创建”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;
