Question

当我尝试在web2py中为scheduller创建一个新模型时，我收到一个错误。该模型如下

`def f():
    a = 2
    return ()

from gluon.scheduler import Scheduler scheduler = Scheduler(db,dict(our_function=f))

我收到以下错误：

`

Traceback (most recent call last):
 File "/home/www-data/web2py/gluon/restricted.py", line 227, in restricted
 exec ccode in environment
 File "/home/www-data/web2py/applications/Home_Lights/models/mtasks.py", line             `42, in <module>`
 Scheduler(db,dict(our_function=f))
 File "/home/www-data/web2py/gluon/scheduler.py", line 587, in __init__
 self.define_tables(db, migrate=migrate)
 File "/home/www-data/web2py/gluon/scheduler.py", line 655, in define_tables
 format='%(task_name)s')
 File "/home/www-data/web2py/gluon/packages/dal/pydal/base.py", line 799, in  `define_table`
 raise SyntaxError('table already defined: %s' % tablename)

    SyntaxError: table already defined: scheduler_task`

我怀疑它与新创建的模型的执行权限有关。任何帮助表示赞赏......？

Answer 1

刚设置：

migrate=False

因此它不会尝试重新创建表格

from gluon.scheduler import Scheduler
scheduler = Scheduler(db,tasks=dict(our_function=f), migrate=False)

web2py的调度程序出错
