结合 web2py 身份验证装饰器

Combining web2py authentication decorators

在 web2py 中,我试图将两个身份验证装饰器组合到一个方法中。

@auth.requires_permission('read', 'inv_header')
@auth.requires_permission('read', 'inv_detail')

我的理解是我是这样做的:

@auth.requires(auth.requires_permission('read', 'inv_header') and \
auth.requires_permission('read', 'inv_detail'))

但是我收到了这个错误。

Traceback (most recent call last):
  File "/opt/web-apps/web2py/gluon/restricted.py", line 224, in restricted
    exec ccode in environment
  File "/opt/web-apps/web2py/applications/niptview/controllers/batch.py", line 317, in <module>

  File "/opt/web-apps/web2py/gluon/tools.py", line 3437, in f
    flag = condition()
TypeError: decorator() takes exactly 1 argument (0 given)

web2py™ 版本 2.9.12-stable+timestamp.2015.01.17.06.11.03 Python Python 2.7.5:/usr/bin/python(前缀:/usr)

有什么我遗漏的吗?

我的环境如下:

web2py™ Version 2.9.12-stable+timestamp.2015.01.17.06.11.03
Python  Python 2.7.5: /usr/bin/python (prefix: /usr)

@auth.requires里面,必须用auth.has_permission,不能用auth.requires_permission(后者是装饰器)
