[web2py] .../default/user/not_authorized

[annet]

In the default controller I adjusted the user() function:

def user():
    """
    exposes:
    ...
    """
    form=auth()
    form[0][-1]
[1].append(INPUT(_type="button",_value="Cancel",_onclick="window.location='%s';"%URL(r=request,f='index')))
    return dict(form=form)


This works well, until a user requests access to a function he doesn't
have access to.  Web2py then redirects to:

http://127.0.0.1:8000/cms/default/user/not_authorized

... which results in the following error;

Traceback (most recent call last):
  File "/Library/Python/2.5/site-packages/web2py_1.87.3/gluon/
restricted.py", line 188, in restricted
    exec ccode in environment

    form[0][-1]
[1].append(INPUT(_type="button",_value="Cancel",_onclick="window.location='%s';"%URL(r=request,f='index')))
IndexError: string index out of range


This is how I fixed the problem, not very elegant, and probably
overlooking other conditions:

def user():
    """
    exposes:
    ...
    """
    form=auth()
    if not request.args(0)=='not_authorized':
        form[0][-1]
[1].append(INPUT(_type="button",_value="Cancel",_onclick="window.location='%s';"%URL(r=request,f='index')))
    return dict(form=form)


I wonder whether there is a better way to solve this problem.


Kind regards,
