[](https://pypi.org/project/django-cache-lock)
[](https://travis-ci.org/Xavier-Lam/django-cache-lock)
[](https://en.cryptobadges.io/donate/1BdJG31zinrMFWxRt2utGBU2jdpv8xSgju)
A simple lock extension for django's cache to prevent concurrent editing.
## Installation
Install django-cache-lock by using pip
pip install django-cache-lock
## Quick Start
You can work with django-cache-lock by using with-statement or decorator.
from django_lock import lock
with lock("global"):
pass
@lock("global")
def foo():
pass
A shortcut to lock model instance
from django.db import models
from django_lock import model_lock
class Foo(models.Model):
bar = models.CharField(max_length=8)
@lock_model
def lock_pk(self):
pass
@lock_model("bar", blocking=False)
def lock_bar(self):
pass
def nolock(self):
pass
foo = Foo()
with lock_model(foo, blocking=False):
nolock()
## Configurations
| key | default | desc |
| --- | --- | --- |
| DJANGOLOCK_PREFIX | "lock:" | lock's key prefix stored in cache |
| DJANGOLOCK_SLEEP | 0.1 | default interval time to acquire a lock if a lock is holded by others |
| DJANGOLOCK_RELEASEONDEL | True | release lock when `__del__` is called if True |
## Advanced usage
For more usages, please read the [code](django_lock.py).
## Supported backends
* django.core.cache.backends.db
* django.core.cache.backends.file
* django.core.cache.backends.locmem
* django.core.cache.backends.memcached
* [django-redis](https://github.com/niwinz/django-redis)
* [django-redis-cache](https://github.com/sebleier/django-redis-cache)
## ATTENTIONS
### locmem backend
* DO NOT USE locmem backend in a product environment.
### memcached backend
* Memcached does not support milliseconds expire time, and its' expire time is not very exact. So memcached lock's timeout time is not as exact as other backends.
### redis backend
* We didn't test distributed redis lock.
## TODOS:
* use memcached's cas to release lock
* reacquire and extend lock
* database backend cache support
