Embedded JSON models with Redis OM for Python

embedded_json.py

import datetime
from typing import Optional

from redis_om import (
    EmbeddedJsonModel,
    JsonModel,
    Field,
    Migrator,
)
from redis_om import get_redis_connection


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 
# and RediSearch modules 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!
redis = get_redis_connection()
Migrator(redis).run()

# Find all customers who live in San Antonio, TX
Customer.find(Customer.address.city == "San Antonio",
              Customer.address.state == "TX")

@chakri622 change to Migrate().run() it will work . Error is that Migrator expects a optional python package to load in background but we are providing redis connection which is not a python package . Its optional and no need to send anything for Migrator just leave it as Migrator().run() .
