## 添加正则表达式 { #add-regular-expressions }

你可以定义一个参数必须匹配的 <dfn title="正则表达式（regex 或 regexp）是用于定义字符串搜索模式的字符序列。">正则表达式</dfn> `pattern`：

{* ../../docs_src/query_params_str_validations/tutorial004_an_py310.py hl[11] *}

这个特定的正则表达式通过以下规则检查接收到的参数值：

- `^`：必须以接下来的字符开头，前面没有其他字符。
- `fixedquery`：值必须精确等于 `fixedquery`。

constraints.NotNull.message = {item} wajib diisi.
constraints.Null.message = {item} harus null.
constraints.Past.message = {item} harus berupa nilai masa lalu.
constraints.Pattern.message = {item} tidak cocok dengan "{regexp}".
constraints.Size.message = Ukuran {item} harus antara {min} dan {max}.
