Overview

cuser will bring you Current user of your django application from anywehere in your code. I know, sounds fantastic ;)

Installing

django-cuser is also avilable at http://pypi.python.org/pypi/django-cuser So it can be install it by pip or easy_install:

$ python pip install django-cuser

Or you can grab the latest version tarball:

$ python setup.py install

To enable django-cuser in your project

• Add cuser to INSTALLED_APPS in your settings.py

• Add cuser.middleware.CuserMiddleware to MIDDLEWARE_CLASSES after the authentication and session middleware.

Who is the current user

To set/get the user info, there is the following API:

from cuser.middleware import CuserMiddleware

Set the current user for this thread. Accepts user objects and login names:

CuserMiddleware.set_user(some_user)

Get the current user or None:

user = CuserMiddleware.get_user()

This will return some_user if there is no current user:

user = CuserMiddleware.get_user(some_user)

Forget the current user. It is always safe to call this, even if there is no current user:

CuserMiddleware.del_user()

The middleware automatically sets/deletes the current user for HTTP requests. For other uses (management commands, scripts), you will need to do this yourself.

CurrentUserField

cuser also provides a CurrentUserField, which can be used for auditing purposes. Use it as follows:

from cuser.fields import CurrentUserField

class MyModel(models.Model):
    ....
    creator = CurrentUserField(add_only=True, related_name="created_mymodels")
    last_editor = CurrentUserField(related_name="last_edited_mymodels")
    ...

This field is a ForeignKey to the django.contrib.auth.models.User model and you can treat it as such.
