Redis cache for managing Django ORM

Project description

ORM for managing cache of django models using redis. Models data can be cached just once and as per requirements it can be fetched using filters.

No-Sql in retrieval of model objects.

Dependencies:

[django >=1.3](https://www.djangoproject.com/)

[redis-py](https://github.com/andymccurdy/redis-py)

[redis](http://redis.io/)

User Manual :

from redis_db.manager import CacheManager

class Person(models.Model):

“”” Person model, contains basic details. “”” name = models.CharField(max_length = 255) email = models.EmailField(max_length = 100) gender = models.ChoiceField(choices = ((‘M’, ‘Male’), (‘F’, ‘Female’)))

#custom managers objects = models.Manager() cache_objects = CacheManager(key = ‘person-cache’)

Creating Cache Data (one time process)

qs = Person.objects.all() Person.cache_objects.store(qs) # qs can be anything, filtered queryset or model object itself

Retrieving Objects from cache (No-SQL)

1- All objects

objs = Person.cache_objects.all() # returns list of Person Objects. Note - Gives back list not queryset,
# because querysets itself is lazy query

2 - Filters usage

objs = Person.cache_objects.filter(gender = ‘M’) # all male Person’s Objects

3 - Get a specific object based on id

obj = Person.cache_objects.get(id= 10)

Note :

For non reference objects there is no query at all but in case of ForiegnKey retreival it makes a query to get that object.
