Primeiro, você precisa importar `BaseModel` do `pydantic`:

{* ../../docs_src/body/tutorial001_py310.py hl[2] *}

## Crie seu modelo de dados { #create-your-data-model }

Então você declara seu modelo de dados como uma classe que herda `BaseModel`.

Utilize os tipos Python padrão para todos os atributos:

{* ../../docs_src/body/tutorial001_py310.py hl[5:9] *}

		t.Fatalf("create user: %v", err)
	}

	if err := DB.Model(&user).Association("Languages").Append(map[string]interface{}{
		"code": "gm2m_map_1", "name": "GMap1",
	}); err != nil {
		t.Fatalf("append map: %v", err)
	}
	AssertAssociationCount(t, user, "Languages", 1, "after append 1 map (generic file)")

	// Append more maps individually

	// utilization to be optimal, instead of blindly throttling the way we are
	// doing below. However the changes that are needed here are a bit involved,
	// further discussion advised. Remove this comment and remove the worker model
	// for this function in future.

### `**user_in.model_dump()` 에 대하여 { #about-user-in-model-dump }

#### Pydantic의 `.model_dump()` { #pydantics-model-dump }

`user_in`은 Pydantic 모델 클래스인 `UserIn`입니다.

Pydantic 모델은 모델 데이터를 포함한 `dict`를 반환하는 `.model_dump()` 메서드를 제공합니다.

따라서, 다음과 같이 Pydantic 객체 `user_in`을 생성할 수 있습니다:
