So you want to customize session auth in CherryPy 3.0? Not a piece of cake, is it? I mean, you could make a custom login_screen function and just attach it in config like this:
[/] tools.session_auth.login_screen = my_login_func
...but that's not obvious if you're not used to metaprogramming (passing functions around). Here's a more class-based way to do it:
import cherrypy from cherrypy.lib import cptools class MySessionAuth(cptools.SessionAuth): def login_screen(self, from_page='..', username='', error_msg=''): return """<html><body> Message: %(error_msg)s!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! <form method="post" action="do_login"> Login: <input type="text" name="username" value="%(username)s" size="10" /><br /> Password: <input type="password" name="password" size="10" /><br /> <input type="hidden" name="from_page" value="%(from_page)s" /><br /> <input type="submit" /> </form> </body></html>""" % {'from_page': from_page, 'username': username, 'error_msg': error_msg} def runtool(cls, **kwargs): sa = cls() for k, v in kwargs.iteritems(): setattr(sa, k, v) return sa.run() runtool = classmethod(runtool) cherrypy.tools.my_session_auth = cherrypy._cptools.HandlerTool(MySessionAuth.runtool)
What I should have done was stuck that 'runtool' method in the builtin SessionAuth class so you'd get it for free. Ah, hindsight. ;)
