# django-maintenance-mode
django-maintenance-mode shows a 503 error page when **maintenance-mode** is **on**.
It works at application level, so your django instance should be up.
It doesn't use database and doesn't prevent database access.
## Installation
1. Run `pip install django-maintenance-mode` or [download django-maintenance-mode](http://pypi.python.org/pypi/django-maintenance-mode) and add the **maintenance_mode** package to your project
2. Add `maintenance_mode` to `settings.INSTALLED_APPS` before custom applications
3. Add `maintenance_mode.middleware.MaintenanceModeMiddleware` to `settings.MIDDLEWARE` as last middleware
4. Add your custom `templates/503.html` file
5. Restart your application server
## Configuration (optional)
### Settings
All these settings are optional, if not defined in `settings.py` the default values (listed below) will be used.
```python
# if True the maintenance-mode will be activated
MAINTENANCE_MODE = None
```
```python
# by default, to get/set the state value a local file backend is used
# if you want to use the db or cache, you can create a custom backend
# custom backends must extend 'maintenance_mode.backends.AbstractStateBackend' class
# and implement get_value(self) and set_value(self, val) methods
MAINTENANCE_MODE_STATE_BACKEND = "maintenance_mode.backends.LocalFileBackend"
# alternatively it is possible to use the default storage backend
MAINTENANCE_MODE_STATE_BACKEND = "maintenance_mode.backends.DefaultStorageBackend"
# alternatively it is possible to use the static storage backend
# make sure that STATIC_ROOT and STATIC_URL are also set
MAINTENANCE_MODE_STATE_BACKEND = "maintenance_mode.backends.StaticStorageBackend"
# alternatively it is possible to use the cache backend
# you can use a custom cache backend by adding a `maintenance_mode` entry to `settings.CACHES`,
# otherwise the default cache backend will be used.
MAINTENANCE_MODE_STATE_BACKEND = "maintenance_mode.backends.CacheBackend"
```
```python
# the fallback value that backends will return in case of failure
# (actually this is only used by "maintenance_mode.backends.CacheBackend")
MAINTENANCE_MODE_STATE_BACKEND_FALLBACK_VALUE = False
```
```python
# by default, a file named "maintenance_mode_state.txt" will be created in the settings.py directory
# you can customize the state file path in case the default one is not writable
MAINTENANCE_MODE_STATE_FILE_PATH = "maintenance_mode_state.txt"
```
```python
# if True admin site will not be affected by the maintenance-mode page
MAINTENANCE_MODE_IGNORE_ADMIN_SITE = False
```
```python
# if True anonymous users will not see the maintenance-mode page
MAINTENANCE_MODE_IGNORE_ANONYMOUS_USER = False
```
```python
# if True authenticated users will not see the maintenance-mode page
MAINTENANCE_MODE_IGNORE_AUTHENTICATED_USER = False
```
```python
# if True the staff will not see the maintenance-mode page
MAINTENANCE_MODE_IGNORE_STAFF = False
```
```python
# if True the superuser will not see the maintenance-mode page
MAINTENANCE_MODE_IGNORE_SUPERUSER = False
```
```python
# list of ip-addresses that will not be affected by the maintenance-mode
# ip-addresses will be used to compile regular expressions objects
MAINTENANCE_MODE_IGNORE_IP_ADDRESSES = ()
```
```python
# the path of the function that will return the client IP address given the request object -> 'myapp.mymodule.myfunction'
# the default function ('maintenance_mode.utils.get_client_ip_address') returns request.META['REMOTE_ADDR']
# in some cases the default function returns None, to avoid this scenario just use 'django-ipware'
MAINTENANCE_MODE_GET_CLIENT_IP_ADDRESS = None
```
Retrieve user's real IP address using [`django-ipware`](https://github.com/un33k/django-ipware):
```python
MAINTENANCE_MODE_GET_CLIENT_IP_ADDRESS = "ipware.ip.get_ip"
```
```python
# the path of the function that will return the response context -> 'myapp.mymodule.myfunction'
MAINTENANCE_MODE_GET_CONTEXT = None
```
```python
# list of urls that will not be affected by the maintenance-mode
# urls will be used to compile regular expressions objects
MAINTENANCE_MODE_IGNORE_URLS = ()
```
```python
# if True the maintenance mode will not return 503 response while running tests
# useful for running tests while maintenance mode is on, before opening the site to public use
MAINTENANCE_MODE_IGNORE_TESTS = False
```
```python
# if True authenticated users will be logged out from their current session
MAINTENANCE_MODE_LOGOUT_AUTHENTICATED_USER = False
```
```python
# the absolute url where users will be redirected to during maintenance-mode
MAINTENANCE_MODE_REDIRECT_URL = None
```
```python
# the type of the response returned during maintenance mode, can be either "html" or "json"
MAINTENANCE_MODE_RESPONSE_TYPE = "html"
```
```python
# the template that will be shown by the maintenance-mode page
MAINTENANCE_MODE_TEMPLATE = "503.html"
```
```python
# the HTTP status code to send
MAINTENANCE_MODE_STATUS_CODE = 503
```
```python
# the value in seconds of the Retry-After header during maintenance-mode
MAINTENANCE_MODE_RETRY_AFTER = 3600 # 1 hour
```
#### Context Processors
Add **maintenance_mode.context_processors.maintenance_mode** to your context_processors list in `settings.py` if you want to access the maintenance_mode status in your templates.
```python
TEMPLATES = [
{
# ...
"OPTIONS": {
"context_processors": [
# ...
"maintenance_mode.context_processors.maintenance_mode",
# ...
],
},
# ...
},
]
```
#### Logging
You can disable emailing 503 errors to admins while maintenance mode is enabled:
```python
LOGGING = {
"filters": {
"require_not_maintenance_mode_503": {
"()": "maintenance_mode.logging.RequireNotMaintenanceMode503",
},
...
},
"handlers": {
...
},
...
}
```
### Context Managers
You can force a block of code execution to run under maintenance mode or not using context managers:
```python
from maintenance_mode.core import maintenance_mode_off, maintenance_mode_on
with maintenance_mode_on():
# do stuff
pass
with maintenance_mode_off():
# do stuff
pass
```
### URLs
Add **maintenance_mode.urls** to `urls.py` if you want superusers able to set maintenance_mode using urls.
```python
urlpatterns = [
# ...
re_path(r"^maintenance-mode/", include("maintenance_mode.urls")),
# ...
]
```
### Views
You can force maintenance mode on/off at view level using view decorators:
#### Function-based views
```python
from maintenance_mode.decorators import force_maintenance_mode_off, force_maintenance_mode_on
@force_maintenance_mode_off
def my_view_a(request):
# never return 503 response
pass
@force_maintenance_mode_on
def my_view_b(request):
# always return 503 response
pass
```
#### Class-based views
```python
from maintenance_mode.decorators import force_maintenance_mode_off, force_maintenance_mode_on
urlpatterns = [
# never return 503 response
path("", force_maintenance_mode_off(YourView.as_view()), name="my_view"),
# always return 503 response
path("", force_maintenance_mode_on(YourView.as_view()), name="my_view"),
]
```
## Usage
### Python
```python
from maintenance_mode.core import get_maintenance_mode, set_maintenance_mode
set_maintenance_mode(True)
if get_maintenance_mode():
set_maintenance_mode(False)
```
or
```python
from django.core.management import call_command
from django.core.management.base import BaseCommand
class Command(BaseCommand):
def handle(self, *args, **options):
call_command("maintenance_mode", "on")
# call your command(s)
call_command("maintenance_mode", "off")
```
### Templates
```html
{% if maintenance_mode %}
{% endif %}
```
### Terminal
Run ``python manage.py maintenance_mode ``
*(**This is not Heroku-friendly because** any execution of heroku run* `manage.py` *will be run on a separate worker dyno, not the web one. Therefore **the state-file is set but on the wrong machine. You should use a custom*** `MAINTENANCE_MODE_STATE_BACKEND`*.)*
### URLs
Superusers can change maintenance-mode using the following urls:
`/maintenance-mode/off/`
`/maintenance-mode/on/`
## Testing
```bash
# clone repository
git clone https://github.com/fabiocaccamo/django-maintenance-mode.git && cd django-maintenance-mode
# create virtualenv and activate it
python -m venv venv && . venv/bin/activate
# upgrade pip
python -m pip install --upgrade pip
# install requirements
pip install -r requirements.txt -r requirements-test.txt
# install pre-commit to run formatters and linters
pre-commit install --install-hooks
# run tests
tox
# or
python runtests.py
# or
python -m django test --settings "tests.settings"
```
