Usage

For example, you have a model user_models.py

from pydantic import BaseModel
from typing import List

class Address(BaseModel):
    street: str
    city: str
    zip_code: str

class User(BaseModel):
    name: str
    age: int
    address: Address
    hobbies: List[str]

Execute the command for converting these models into mapping json:

pydantic2es --input ./user_models.py --output_format pretty

And you will obtain the following result:

{
    "mappings": {
        "properties": {
            "name": {
                "type": "keyword"
            },
            "age": {
                "type": "integer"
            },
            "address": {
                "type": "nested",
                "properties": {
                    "street": {
                        "type": "keyword"
                    },
                    "city": {
                        "type": "keyword"
                    },
                    "zip_code": {
                        "type": "keyword"
                    }
                }
            },
            "hobbies": {
                "type": "keyword"
            }
        }
    }
