Redis OM Python makes it easy to model Redis data in your Python applications.
Why Redis OM?
Redis OM provides high-level abstractions that make it easy to model and query data in Redis with modern Python applications.
This preview release contains the following features:
- Declarative object mapping for Redis objects
- Declarative secondary-index generation
- Fluent APIs for querying Redis
import datetime from typing import Optional from pydantic import EmailStr from redis_om import HashModel class Customer(HashModel): first_name: str last_name: str email: EmailStr join_date: datetime.date age: int bio: Optional[str] # First, we create a new `Customer` object: andrew = Customer( first_name="Andrew", last_name="Brookins", email="andrew.brookins@example.com", join_date=datetime.date.today(), age=38, bio="Python developer, works at Redis, Inc." ) # The model generates a globally unique primary key automatically # without needing to talk to Redis. print(andrew.pk) # > "01FJM6PH661HCNNRC884H6K30C" # We can save the model to Redis by calling `save()`: andrew.save() # Expire the model after 2 mins (120 seconds) andrew.expire(120) # To retrieve this customer with its primary key, we use `Customer.get()`: assert Customer.get(andrew.pk) == andrew
