Installation

1. Either checkout django_su from GitHub, or install using pip :

   .. code-block:: bash

   pip install django-su
   

2. Add django_su to your INSTALLED_APPS. Make sure you put it before django.contrib.admin :

   .. code-block:: python

   INSTALLED_APPS = (
       ...
       'django_su',  # must be before ``django.contrib.admin``
       'django.contrib.admin',
   )
   

3. Add SuBackend to AUTHENTICATION_BACKENDS :

   .. code-block:: python

   AUTHENTICATION_BACKENDS = (
       ...
       'django_su.backends.SuBackend',
   )
   

4. Update your urls.py file :

   .. code-block:: python

   urlpatterns = [
       url(r'^su/', include('django_su.urls')),
       ...
   ]
   

And that should be it!

Please see example application. This application is used to manually test the functionalities of this package. This also serves as a good example.

django-su requires Django 1.5 or above.

External dependencies (optional, but recommended)

The following apps are optional but will enhance the user experience:

* The 'login su' form will render using `django-form-admin`_
* The user selection widget will render using `django-ajax-selects`_

Note that `django-ajax-selects`_ requires the following settings:

.. code-block:: python

    AJAX_LOOKUP_CHANNELS = {'django_su':  dict(model='auth.user', search_field='username')}


Configuration (optional)
------------------------

There are various optional configuration options you can set in your ``settings.py``

.. code-block:: python

    # URL to redirect after the login.
    # Default: "/"
    SU_LOGIN_REDIRECT_URL = "/"

    # URL to redirect after the logout.
    # Default: "/"
    SU_LOGOUT_REDIRECT_URL = "/"

    # A function specifying the permissions a user requires in order
    # to use the django-su functionality.
    # Default: None
    SU_LOGIN_CALLBACK = "example.utils.su_login_callback"

    # A function to override the django.contrib.auth.login(request, user)
    # view, thereby allowing one to set session data, etc.
    # Default: None
    SU_CUSTOM_LOGIN_ACTION = "example.utils.custom_login"

Usage
-----

Go and view a user in the admin interface and look for a new "Login
as" button in the top right.

Once you have su'ed into a user, you can get exit back into your
original user by navigating to ``/su/`` in your browser.

How to Notify superuser when connected with another user

This option warns the superuser when working with another user as initially logged in. To activate this option perform:

1. Add django_su.context_processors.is_su to TEMPLATE_CONTEXT_PROCESSORS :

   .. code-block:: python

   TEMPLATE_CONTEXT_PROCESSORS = (
       ...
       'django_su.context_processors.is_su',
   )
   

2. In your base.html include su/is_su.html snippet :

   .. code-block:: html+django

   {% include "su/is_su.html" %}
   

How to use django-su with a custom user model (AUTH_USER_MODEL)

Django-su should function normally with a custom user model. However,
your `ModelAdmin` in your `admin.py` file will need tweaking as follows:

.. code-block:: python

   # Within your admin.py file
   from django.contrib import admin
   from django.contrib.auth.admin import UserAdmin

   from . import models

    @admin.register(models.CustomUser)
    class CustomUserAdmin(UserAdmin):
        # The following two lines are needed:
        change_form_template = "admin/auth/user/change_form.html"
        change_list_template = "admin/auth/user/change_list.html"

This ensures the Django admin will use the correct template customisations for
your custom user model.
