Auth Patches
============

Usage::

    from web2py_utils import auth_patches

set_controller
--------------

This module includes a simple patch to auth to fix the controller URLS.

Unfortunately auth has a bug that the URLS are actually generated when you
create the object. So setting auth.settings.controller will not fix it.

Usage::

    >>> auth=Auth(globals(), db)
    >>> auth.settings.login_url
    /welcome/default/user/login
    >>> auth.controller = 'admin'
    >>> auth.settings.login_url
    /welcome/default/user/login
    
    >>> auth_patches.set_controller(auth, controller='admin', function='user')

    >>> auth.settings.login_url
    /welcome/admin/user/login
