login_handler

[shaw1ea]

Where is the login_handler method located in the source code for tg2?
I am trying to implement post logon url so that the user is directed
to an appropriate page after they log in. How do I specify which page
the user will get directed to based on their username and password.
The users permissions must be used to determine the proper page. Can
someone explain this or direct me to an example that show how to do
this?

Have a look at the post_login method of RootController. Change the
last few lines to

userid = request.identity['repoze.who.userid']
if came_from.decode() == '/':
came_from = tg.url(get_userpage(userid))
flash(....)
redirect(came_from)

get_userpage should contain your page access logic and return a url
string based on userid

I got this question the same with you, do anybody know the true source code location for tg2?

I'm not sure why this is considered a mystery.

The default login handler is located at MYAPP.controllers.root:RootController.login

The default login form is located at MYAPP/templates/login.html

The default login form handler (once authentication is completed by repoze.who) is located at MYAPP.controllers.root:RootController.post_login

The means of controlling authentication and authorization are determined by repoze.who and repoze.what, respectively. The documentation for those two packages covers the needed steps on how to customize them. While that documentation can be difficult to understand (I've tried, and it's not easy for me), it is there, and does cover how to customize them.

If there's something I've missed, please follow up on this, and I'll try to answer then.
