A simple Django reusable application for locking down an entire site (or particular views), with customizable date ranges and preview authorization.


Install from PyPI with easy_install or pip:

pip install django-lockdown

or get the in-development version:

pip install django-lockdown==tip

To use django-lockdown in your Django project:

  1. Add 'lockdown' to your INSTALLED_APPS setting.
  2. To enable admin preview of locked-down sites or views with passwords, set the LOCKDOWN_PASSWORDS setting to a tuple of one or more plain-text passwords.
  3. Protect the entire site by using middleware, or protect individual views by applying a decorator to them.

For more advanced customization of admin preview authorization, see the LOCKDOWN_FORM setting.


django-lockdown requires Django 1.1 or later.


Using the middleware

To lock down the entire site, add the lockdown middleware to your MIDDLEWARE_CLASSES setting:

    # ...

Optionally, you may also add URL regular expressions to a LOCKDOWN_URL_EXCEPTIONS setting.

Using the decorator

Apply the decorator to individual views you want to protect. For example:

def secret_page(request):
    # ...

The decorator accepts four arguments:

The form to use for providing an admin preview, rather than the form referenced by LOCKDOWN_FORM. Note that this must be an actual form class, not a module reference like the setting.
The date to use rather than the date provided by LOCKDOWN_UNTIL.
The date to use rather than the date provided by LOCKDOWN_AFTER.
A preview logout key to use, rather than the one provided by LOCKDOWN_LOGOUT_KEY.
The session key to use, rather than the one provided by LOCKDOWN_SESSION_KEY.
A list of regular expressions for which matching urls can bypass the lockdown (rather than using those defined in LOCKDOWN_URL_EXCEPTIONS).

Any further keyword arguments are passed to the admin preview form. The default form accepts one argument:

A tuple of passwords to use, rather than the ones provided by LOCKDOWN_PASSWORDS.



One or more plain-text passwords which allow the previewing of the site or views protected by django-lockdown:

LOCKDOWN_PASSWORDS = ('letmein', 'beta')

If this setting is not provided (and the default LOCKDOWN_FORM is being used), there will be no admin preview for locked-down pages.

If a LOCKDOWN_FORM other than the default is used, this setting has no effect.


An optional list/tuple of regular expressions to be matched against incoming URLs. If a URL matches a regular expression in this list, it will not be locked. For example:

    r'^/about/$',   # unlock /about/
    r'\.json$',   # unlock JSON API


Used to lock the site down up until a certain date. Set to a datetime.datetime object.

If neither LOCKDOWN_UNTIL nor LOCKDOWN_AFTER is provided (the default), the site or views will always be locked.


Used to lock the site down after a certain date. Set to a datetime.datetime object.



A key which, if provided in the querystring of a locked URL, will log out the user from the preview.


The default lockdown form allows admin preview by entering a preset plain-text password (checked, by default, against the LOCKDOWN_PASSWORDS setting). To set up more advanced methods of authenticating access to locked-down pages, set LOCKDOWN_FORM to the Python dotted path to a Django Form subclass. This form will be displayed on the lockout page. If the form validates when submitted, the user will be allowed access to locked pages:

LOCKDOWN_FORM = 'path.to.my.CustomLockdownForm'

A form for authenticating against django.contrib.auth users is provided with django-lockdown (use LOCKDOWN_FORM = 'lockdown.forms.AuthForm'). It accepts two keyword arguments (in the lockdown decorator):

Only allow staff members to preview. Defaults to True (but the default can be provided as a LOCKDOWN_AUTHFORM_STAFF_ONLY setting).
Only allow superusers to preview. Defaults to False (but the default can be provided as a LOCKDOWN_AUTHFORM_SUPERUSERS_ONLY setting).


If using lockdown.forms.AuthForm and this setting is True, only staff users will be allowed to preview (True by default).

Has no effect if not using lockdown.forms.AuthForm.


If using lockdown.forms.AuthForm and this setting is True, only superusers will be allowed to preview (False by default). Has no effect if not using lockdown.forms.AuthForm.


Once a client is authorized for admin preview, they will continue to be authorized for the remainder of their browsing session (using Django's built-in session support). LOCKDOWN_SESSION_KEY defines the session key used; the default is 'lockdown-allow'.


Django-lockdown uses a single template, lockdown/form.html. The default template displays a simple "coming soon" message and the preview authorization form.

If you override this template, the lockdown preview form is available in the template context as form.
