Override current user based on subdomain

Project description


Overrides current user based on host prefix. For example any request to
```` (format can be changed in settings) becomes
request as if you were logged in as user with ID 5. This allows you to
be logged in as different users in different tabs **at the same time**
without losing your primary authenticated user.

Works only if you're logged in as superuser by default (can be changed
in settings).

Also gives you big red banner on top of every page if your user is


- Your DNS server should resolve subdomains ``*.user.<your domain>`` to
the same IP address as main domain.
- Your project should not use absolute link generation or any other
technic that can change current subdomain. It is a more inconvenience
than requirement though.

Installing django-host-user-override

1. Install the package from PyPI:
``pip install django-host-user-override``

2. Add ``host_user_override`` to ``INSTALLED_APPS``:

.. code:: python


3. Add ``HostUserOverrideMiddleware`` right after

.. code:: python


4. Update your ```` file to support subdomains (don't forget
about DNS as well): \`\`\`python ALLOWED\_HOSTS = ['']


5. Set new ``change_form.html`` template in ``UserAdmin``: \`\`\`python

@admin.register(User) class CustomUserAdmin(UserAdmin):
change\_form\_template = 'host\_user\_override/change\_form.html' \`\`\`

Optional settings

6. Update ```` if you want host pattern other than
``<id>.user.<domain>``. Example for ``u<id>.<domain>``: \`\`\`python
HOSTUSEROVERRIDE\_HOST\_REGEXP = r'u(:raw-latex:`\d`+)..+'

HOSTUSEROVERRIDE\_HOST\_SUB\_REGEXP = r'u:raw-latex:`\d`+.'

HOSTUSEROVERRIDE\_REDIRECT\_URL\_FORMAT = 'http://u{user\_id}.{host}/'


7. Set ``HOSTUSEROVERRIDE_PERMISSION_CHECK`` to customize required
permissions. Should be function that takes 2 positional arguments:
current user and desired user.

8. Set ``HOSTUSEROVERRIDE_FORCE_ACTIVE`` to force overriden user to be
active even when he is actually disabled.


Open any non-superuser in Django Admin and press 'Login as multiuser'
