## Аліаси параметрів { #alias-parameters }

Уявіть, що ви хочете, щоб параметр називався `item-query`.

Наприклад:

```
http://127.0.0.1:8000/items/?item-query=foobaritems
```

With `Form` you can declare the same configurations as with `Body` (and `Query`, `Path`, `Cookie`), including validation, examples, an alias (e.g. `user-name` instead of `username`), etc.

/// info

`Form` is a class that inherits directly from `Body`.

// Name returns the name or alias of the column.

		return ct.NameValue.String

	return ct.SQLColumnType.Name()

## Alias para parámetros { #alias-parameters }

Imagina que quieres que el parámetro sea `item-query`.

Como en:

```
http://127.0.0.1:8000/items/?item-query=foobaritems
```

Con `Form` puedes declarar las mismas configuraciones que con `Body` (y `Query`, `Path`, `Cookie`), incluyendo validación, ejemplos, un alias (por ejemplo, `user-name` en lugar de `username`), etc.

/// info | Información

`Form` es una clase que hereda directamente de `Body`.

///

/// tip | Consejo

The following commands set a local alias, validate the server information, create a bucket, copy data to that bucket, and list the contents of the bucket.

```sh
mc alias set local http://localhost:9000 minioadmin minioadmin
mc admin info
mc mb data
mc cp ~/Downloads/mydata data/
mc ls data/
```
