Dependencies

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:

MIDDLEWARE_CLASSES = (
    # ...
    'lockdown.middleware.LockdownMiddleware',
)

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:

@lockdown()
def secret_page(request):
    # ...

The decorator accepts four arguments:

form

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.

until_date

The date to use rather than the date provided by LOCKDOWN_UNTIL.

after_date

The date to use rather than the date provided by LOCKDOWN_AFTER.

logout_key

A preview logout key to use, rather than the one provided by LOCKDOWN_LOGOUT_KEY.

session_key

The session key to use, rather than the one provided by LOCKDOWN_SESSION_KEY.

url_exceptions

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:

passwords

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

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.

LOCKDOWN_URL_EXCEPTIONS

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:

LOCKDOWN_URL_EXCEPTIONS = (
    r'^/about/$',   # unlock /about/
    r'\.json$',   # unlock JSON API
)

LOCKDOWN_UNTIL

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.

LOCKDOWN_AFTER

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

See also: LOCKDOWN_UNTIL.

LOCKDOWN_LOGOUT_KEY

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

LOCKDOWN_FORM

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):

staff_only

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

superusers_only

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

LOCKDOWN_AUTHFORM_STAFF_ONLY

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.

LOCKDOWN_AUTHFORM_SUPERUSERS_ONLY

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.

LOCKDOWN_SESSION_KEY

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'.
