Built in events¶

Login and Logout¶

portal.authentication.signals

Some default events are raised upon logging in and logging out. The login process will first authenticate against the authentication backends, before doing the login proper. These are the signals with the classes that dispatch them:

portal.authentication.views.LoginView

portal_pre_authenticate

portal_post_authenticate

portal_pre_login

portal_post_login

portal.authentication.views.LogoutView

portal_pre_logout

portal_post_logout

These events are passed through with the following attributes:

sender
The class that just had an instance created.

instance
The actual instance of the model that’s just been created.

args
A list of positional arguments passed.

kwargs
A dictionary of keyword arguments passed.

An example of listening to portal_post_login from within a plugin:

from portal.authentication.signals import portal_post_login

def post_login_handler(instance, **kwargs):
    from portal.authentication.views import LoginView
    if issubclass(kwargs['sender'],LoginView):
        print(instance)
        print(kwargs['sender'])


portal_post_login.connect(post_login_handler)

This will print out the sender (class), instance (the user object) and any other keyword arguments.

If the above example is placed in a file plistner.py this should either be under the main plugin directory or within a directory imported by __init__.py under the plugins directory.
