How to set custom JSON parameter name with pydantic?

Question

I have JSON with params from DB:

{
"model": "Example",
"weight": "1"
}

I need to change "model" key in output JSON with pydantic (set it custom name)

{
"changed_key": "Example",
"weight": "1"
}

You should use serialization_alias parameter

from pydantic import BaseModel, Field


class Model(BaseModel):
    model: str = Field(..., serialization_alias='changed_key')
    weight: str
