如果你寫帶有 Python 型別的程式碼：

```python
from datetime import date

from pydantic import BaseModel

# 宣告一個變數為 string
# 並在函式中獲得 editor support
def main(user_id: str):
    return user_id


# 宣告一個 Pydantic model
class User(BaseModel):
    id: int
    name: str
    joined: date
```


可以像這樣來使用：

```python

여러분은 타입을 이용한 표준 파이썬을 다음과 같이 적을 수 있습니다:

```Python
from datetime import date

from pydantic import BaseModel

# 변수를 str로 선언
# 그 후 함수 안에서 편집기 지원을 받으세요
def main(user_id: str):
    return user_id


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

위의 코드는 다음과 같이 사용될 수 있습니다:

```Python

	} else if len(stmt.Schema.PrimaryFields) != 1 {
		t.Errorf("should have only one primary field with embedded struct, but got %v", len(stmt.Schema.PrimaryFields))
	}

	for _, name := range []string{"user_id", "user_name", "user_email"} {
		if !DB.Migrator().HasColumn(&HNPost{}, name) {
			t.Errorf("should has prefixed column %v", name)
		}
	}

	// save embedded struct
	DB.Save(&HNPost{BasePost: BasePost{Title: "news"}})

    }

    /**
     * Converts an underscore-separated string to camel case.
     * <p>
     * Usage example:
     * </p>
     *
     * <pre>
     * StringUtil.camelize("USER_ID")  = "UserId"
     * </pre>
     *
     * @param s
     *            the text
     * @return the resulting string
     */
    public static String camelize(String s) {
        if (s == null) {

型を使用した標準的なPythonを記述します:

```Python
from datetime import date

from pydantic import BaseModel

# Declare a variable as a str
# and get editor support inside the function
def main(user_id: str):
    return user_id


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

これは以下のように用いられます:

```Python

		if user.Account.Number != "" {
			if !user.Account.UserID.Valid {
				t.Errorf("Account's foreign key should be saved")
			} else {
				var account Account
				db(unscoped).First(&account, "user_id = ?", user.ID)
				AssertObjEqual(t, account, user.Account, "ID", "CreatedAt", "UpdatedAt", "DeletedAt", "UserID",
					"Number")
			}
		}
	})

	t.Run("Pets", func(t *testing.T) {

		// callMethod do
		tx2 := tx1.Find(&User{}).Session(&gorm.Session{NewDB: true})
		// trx in hooks
		return tx2.Transaction(func(tx3 *gorm.DB) error {
			return tx3.Where("user_id", user.ID).Delete(&Account{}).Error
		})
	})
	if err != nil {
		t.Error(err)
	}
}

func TestTransactionWithDefaultTimeout(t *testing.T) {

		t.Fatalf("user's updated at should not zero, %v", users[0].UpdatedAt)
	}

	if rowsAffected := DB.Model(&User{}).Clauses(clause.From{Tables: []clause.Table{{Name: "accounts"}}}).Where("accounts.user_id = users.id AND accounts.number = ? AND accounts.deleted_at IS NULL", users[0].Account.Number).Update("name", "franco").RowsAffected; rowsAffected != 1 {
		t.Errorf("should only update one record, but got %v", rowsAffected)
	}

	}

	query := DB.Model(&User{}).
		Select("users.id as users_id, users.name as users_name, pets.id as pets_id, pets.name as pets_name").
		Joins("inner join pets on pets.user_id = users.id")

	if err := DB.Migrator().CreateView("users_pets", gorm.ViewOption{Query: query}); err != nil {
		t.Fatalf("Failed to crate view, got %v", err)
	}

	var count int64

* Allow path parameters to have default values (e.g. `None`) and discard them instead of raising an error.
    * This allows declaring a parameter like `user_id: str = None` that can be taken from a query parameter, but the same *path operation* can be included in a router with a path `/users/{user_id}`, in which case will be taken from the path and will be required.
