return user_id


# Pydantic 모델
class User(BaseModel):
    id: int
    name: str
    joined: date
```

위의 코드는 다음과 같이 사용될 수 있습니다:

```Python
my_user: User = User(id=3, name="John Doe", joined="2018-07-19")

second_user_data = {
    "id": 4,
    "name": "Mary",
    "joined": "2018-11-30",
}

my_second_user: User = User(**second_user_data)
```

	// Create company and user with company
	company := Company{Name: "Electronics"}
	if err := DB.Create(&company).Error; err != nil {
		t.Fatalf("create company: %v", err)
	}

	user := User{Name: "John", Age: 25, CompanyID: &company.ID}
	if err := DB.Create(&user).Error; err != nil {
		t.Fatalf("create user: %v", err)
	}

	// Verify association exists
	AssertAssociationCount(t, &user, "Company", 1, "before")

class User(BaseModel):

これは以下のように用いられます:

```Python
my_user: User = User(id=3, name="John Doe", joined="2018-07-19")

second_user_data = {
    "id": 4,
    "name": "Mary",
    "joined": "2018-11-30",
}

my_second_user: User = User(**second_user_data)
```
