And then you can also have a path `/users/{user_id}` to get data about a specific user by some user ID.

Because *path operations* are evaluated in order, you need to make sure that the path for `/users/me` is declared before the one for `/users/{user_id}`:

{* ../../docs_src/path_params/tutorial003_py310.py hl[6,11] *}

    go install github.com/microsoft/go-sqlcmd/cmd/sqlcmd@latest || true
    for query in \
      "IF DB_ID('gorm') IS NULL CREATE DATABASE gorm" \
      "IF SUSER_ID (N'gorm') IS NULL CREATE LOGIN gorm WITH PASSWORD = 'LoremIpsum86';" \
      "IF USER_ID (N'gorm') IS NULL CREATE USER gorm FROM LOGIN gorm; ALTER SERVER ROLE sysadmin ADD MEMBER [gorm];"
    do

在建立「路徑操作」時，你可能會遇到有固定路徑的情況。

像是 `/users/me`，假設它用來取得目前使用者的資料。

然後你也可能有一個路徑 `/users/{user_id}` 用來依使用者 ID 取得特定使用者的資料。

因為「路徑操作」會依宣告順序來比對，你必須確保 `/users/me` 的路徑在 `/users/{user_id}` 之前宣告：

{* ../../docs_src/path_params/tutorial003_py310.py hl[6,11] *}

否則，`/users/{user_id}` 的路徑也會匹配 `/users/me`，並「認為」它收到一個值為 `"me"` 的 `user_id` 參數。

同樣地，你不能重新定義同一路徑操作：

{* ../../docs_src/path_params/tutorial003b_py310.py hl[6,11] *}

        assertNull(StringUtil.camelize(null));
        assertEquals("Emp", StringUtil.camelize("EMP"));
        assertEquals("AaaBbb", StringUtil.camelize("AAA_BBB"));
        assertEquals("UserId", StringUtil.camelize("USER_ID"));
    }

    /**
     * @throws Exception
     */
    @Test
    public void testDecamelize() throws Exception {
        assertNull(StringUtil.decamelize(null));

			References: []Reference{{"ID", "User", "UserID", "UserSpeak", "", true}, {"Code", "Language", "LanguageCode", "UserSpeak", "", false}},
		},
		{
			Name: "Friends", Type: schema.Many2Many, Schema: "User", FieldSchema: "User",
			JoinTable: JoinTable{Name: "user_friends", Table: "user_friends", Fields: []schema.Field{
				{
					Name: "UserID", DBName: "user_id", BindNames: []string{"UserID"}, DataType: schema.Uint,

You write standard Python with types:

```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
```

That can then be used like:

```Python

For example, let's say you have 4 API endpoints (*path operations*):

* `/items/public/`
* `/items/private/`
* `/users/{user_id}/activate`
* `/items/pro/`

then you could add different permission requirements for each of them just with dependencies and sub-dependencies:

```mermaid
graph TB

current_user(["current_user"])

		if err := DB.Session(&gorm.Session{FullSaveAssociations: true}).Updates(&cusUser).Error; err != nil {
			t.Fatalf("errors happened when create: %v", err)
		}

		var account2 CustomizeAccount
		DB.Find(&account2, "user_id = ?", cusUser.ID)
		AssertEqual(t, account2.Number, number)
		AssertEqual(t, account2.Number2, cusUser.Account.Number2)
	})

		{
			"name":    "cat",
			"user_id": gorm.Expr("(?)", DB.Table("(?) as tmp", subQuery).Select("@uid:=id")),
		},
		{
			"name":    "dog",
			"user_id": gorm.Expr("@uid"),
		},
	})

여러분은 타입이 있는 표준 Python을 다음과 같이 작성합니다:

```Python
from datetime import date

from pydantic import BaseModel

# 변수를 str로 선언합니다
# 그리고 함수 내부에서 편집기 지원을 받습니다
def main(user_id: str):
    return user_id


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

그 다음 다음과 같이 사용할 수 있습니다:

```Python
