Redis cache for managing Django ORM
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.
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 usageobjs = Person.cache_objects.filter(gender = ‘M’) # all male Person’s Objects
3 - Get a specific object based on idobj = Person.cache_objects.get(id= 10)
For non reference objects there is no query at all but in case of ForiegnKey retreival it makes a query to get that object.
