python - Is it possible to use Pydantic BaseModel orm_mode to get data from gui class

Question

Is it possible to use model class which inherit from Pydantic.BaseModel to get data from a GUI class by setting orm_mode= true, like it used with databases

from typing import List
from sqlalchemy import Column, Integer, String
from sqlalchemy.dialects.postgresql import ARRAY
from sqlalchemy.ext.declarative import declarative_base
from pydantic import BaseModel, constr

Base = declarative_base()


class CompanyOrm(Base):
    __tablename__ = 'companies'
    id = Column(Integer, primary_key=True, nullable=False)
    public_key = Column(String(20), index=True, nullable=False, unique=True)
    name = Column(String(63), unique=True)
    domains = Column(ARRAY(String(255)))


class CompanyModel(BaseModel):
    id: int
    public_key: constr(max_length=20)
    name: constr(max_length=63)
    domains: List[constr(max_length=255)]

    class Config:
        orm_mode = True

'''' If it is possible how may i do it ?

Answer 1

It is assumed that ORM mode supports arbitrary classes, not just databases ORM (it is named so because it is usually used in conjunction with it). More detailed here.

Example with regular class:

from pydantic import BaseModel


class SomeClass:
    def __init__(self):
        self.id = 100
        self.name = "some_name"


class SomeModel(BaseModel):
    id: int
    name: str

    class Config:
        orm_mode = True


print(SomeModel.from_orm(SomeClass()))  # id=100 name='some_name'
