# Embedded Models
**NOTE:** This documentation is a stub, using the same embedded JSON model example as the README.
Redis OM can store and query **nested models** like any document database, with the speed and power you get from Redis. Let's see how this works.
In the next example, we'll define a new `Address` model and embed it within the `Customer` model.
```python
import datetime
from typing import Optional
from redis_om import (
EmbeddedJsonModel,
JsonModel,
Field,
Migrator
)
class Address(EmbeddedJsonModel):
address_line_1: str
address_line_2: Optional[str]
city: str = Field(index=True)
state: str = Field(index=True)
country: str
postal_code: str = Field(index=True)
class Customer(JsonModel):
first_name: str = Field(index=True)
last_name: str = Field(index=True)
email: str = Field(index=True)
join_date: datetime.date
age: int = Field(index=True)
bio: Optional[str] = Field(index=True, full_text_search=True,
default="")
# Creates an embedded model.
address: Address
# With these two models and a Redis deployment with the RedisJSON
# module installed, we can run queries like the following.
# Before running queries, we need to run migrations to set up the
# indexes that Redis OM will use. You can also use the `migrate`
# CLI tool for this!
Migrator().run()
# Find all customers who live in San Antonio, TX
Customer.find(Customer.address.city == "San Antonio",
Customer.address.state == "TX")
```

## Redsi OM with Asyncio
Redis OM is designed to work with asyncio, so you can use Redis OM models asynchronously within FastAPI applications.
The only difference is that you import the Redis OM models from the `aredis_om` module instead of the `redis_om` module.
Here is the previous FastAPI app, but using asyncio-compatible Redis OM code:
```python
import datetime
from typing import Optional
import aioredis
from fastapi import FastAPI, HTTPException
from starlette.requests import Request
from starlette.responses import Response
from fastapi_cache import FastAPICache
from fastapi_cache.backends.redis import RedisBackend
from fastapi_cache.decorator import cache
from pydantic import EmailStr
from aredis_om import HashModel, NotFoundError # <- Notice, we import from aredis_om
from aredis_om import get_redis_connection
# This Redis instance is tuned for durability.
REDIS_DATA_URL = "redis://localhost:6380"
# This Redis instance is tuned for cache performance.
REDIS_CACHE_URL = "redis://localhost:6381"
class Customer(HashModel):
first_name: str
last_name: str
email: EmailStr
join_date: datetime.date
age: int
bio: Optional[str]
app = FastAPI()
@app.post("/customer")
async def save_customer(customer: Customer):
# We can save the model to Redis by calling `save()`:
return await customer.save() # <- We use await here
@app.get("/customers")
async def list_customers(request: Request, response: Response):
# To retrieve this customer with its primary key, we use `Customer.get()`:
return {"customers": await Customer.all_pks()} # <- We also use await here
@app.get("/customer/{pk}")
@cache(expire=10)
async def get_customer(pk: str, request: Request, response: Response):
# To retrieve this customer with its primary key, we use `Customer.get()`:
try:
return await Customer.get(pk) # <- And, finally, one more await!
except NotFoundError:
raise HTTPException(status_code=404, detail="Customer not found")
@app.on_event("startup")
async def startup():
r = aioredis.from_url(REDIS_CACHE_URL, encoding="utf8",
decode_responses=True)
FastAPICache.init(RedisBackend(r), prefix="fastapi-cache")
# You can set the Redis OM URL using the REDIS_OM_URL environment
# variable, or by manually creating the connection using your model's
# Meta object.
Customer.Meta.database = get_redis_connection(url=REDIS_DATA_URL,
decode_responses=True)
```
**NOTE:** The modules `redis_om` and `aredis_om` are identical in almost every
way. The only difference is that the `aredis_om` returns coroutines that you must
`await`.

# Querying
**NOTE:** This documentation is a stub that uses examples from other documentation in this project (the README, the Getting Started guide, etc.). Detailed documentation on querying in a work in progress.
Querying in Redis OM uses a rich expression syntax inspired by the Django ORM, SQLAlchemy, and Peewee.
In the following example, we define `Address` and `Customer` models for use with a Redis database that has the [RedisJSON](redis-json-url) module installed.
With these two classes defined, we can query on any indexed fields in the models -- including indexed fields within embedded models.
```python
import datetime
from typing import Optional
from redis_om import (
EmbeddedJsonModel,
JsonModel,
Field,
Migrator
)
class Address(EmbeddedJsonModel):
address_line_1: str
address_line_2: Optional[str]
city: str = Field(index=True)
state: str = Field(index=True)
country: str
postal_code: str = Field(index=True)
class Customer(JsonModel):
first_name: str = Field(index=True)
last_name: str = Field(index=True)
email: str = Field(index=True)
join_date: datetime.date
age: int = Field(index=True)
bio: Optional[str] = Field(index=True, full_text_search=True,
default="")
# Creates an embedded model.
address: Address
# Before running queries, we need to run migrations to set up the
# indexes that Redis OM will use. You can also use the `migrate`
# CLI tool for this!
Migrator().run()
# Here are a few example queries that use these two models...
# Find all customers with the last name "Brookins"
Customer.find(Customer.last_name == "Brookins").all()
# Find all customers that do NOT have the last name "Brookins"
Customer.find(Customer.last_name != "Brookins").all()
# Find all customers whose last name is "Brookins" OR whose age is
# 100 AND whose last name is "Smith"
Customer.find((Customer.last_name == "Brookins") | (
Customer.age == 100
) & (Customer.last_name == "Smith")).all()
# Find all customers who live in San Antonio, TX
Customer.find(Customer.address.city == "San Antonio",
Customer.address.state == "TX")
```

# Testing Your Models
**NOTE:** This documentation is a Work in Progress.
Writing tests that use a Redis OM model requires some setup. For now, review the tests in the redis-om-python project for examples.
