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
