如何将参数传递给已翻译的验证错误消息

Question

在Symfony2中，you can translate your validation error messages：

验证文件

# src/Acme/BlogBundle/Resources/config/validation.yml
Acme\BlogBundle\Entity\Author:
    properties:
        name:
            - NotBlank: { message: "author.name.not_blank" }

翻译文件

# validators.en.yml
author.name.not_blank: Please enter an author name.

但是如何将参数传递给翻译文件，例如我想通过所需的最小或最大长度？

author.name.min_length: "Required length: %limit% characters."

Answer 1

怎么样，

Acme\BlogBundle\Entity\Author:
    properties:
        name:
            - NotBlank: { message: "author.name.not_blank" }
            - Length:
                min: 3
                minMessage: "author.name.min_length"

您的翻译文件应包含

# validators.en.yml
author.name.not_blank: Please enter an author name.
author.name.min_length: "Required length: {{ limit }} characters."

此处的{{ limit }}占位符将适合长度约束的min pamarater。
