How to do validation using Pydantic with replacing a value from a dictionary?

Question

Python

I'm making a small parser.
There is yml (yml_catalog from 1C for Yandex with product descriptions)
Products from yml are parsed and loaded into woocommerce via API. There are no questions with this.
But there is a moment. The yml has key": "производитель".
Woocommerce has key": "производитель", but the list is different.
Now I just compare the value from yml to the value from woocommerce.
The question is, can this (value replacement) be done by running json through pydantic ???

Answer 1

with a live example it would be easier, but it is possible to process values ​​through @validator
Implementation example, of course, you can do more complex processing

from pydantic import BaseModel, validator

keys = {
    '1': 'one'
}


class User(BaseModel):
    name: str = ''
    key: str = ''

    @validator('key')
    def update_key(cls, value):
        return keys.get(value, value)


user_1 = User.parse_obj({'name': 'Test User', 'key': '1'})
user_2 = User.parse_obj({'name': 'Test User', 'key': '2'})

print(user_1)
print(user_2)

name='Test User' key='one'
name='Test User' key='2'
