Data::FormValidator 打印无效数据的 hashref 而不是字符串

我们开发了一个 Catalyst 应用程序，我的同事开始使用 Catalyst::Plugin::FormValidator 实现表单验证，它提供了 Data::FormValidator 的快捷方式。

验证似乎成功，并且缺失条目的显示有效。但是，当显示不匹配约束的详细信息时，页面包含一个哈希引用，例如 HASH(0x784d80)。

这是我们用来配置验证器的哈希（首先测试 FormValidator 的所有示例代码）：

{
    required => [qw/email age sex/],
    optional => [qw/city name/],
    filters  => [qw/trim/],

    constraints => {
        name => sub { length $_[1] >= 2 },
        sex => sub  { $_[1] =~ /^(male)|(female)$/},
        age => sub { $_[1] =~ /^[0-9]{1,2}$/ },
        email => sub { Email::Valid->address(lc($_[1])) },
        city => sub { length $_[1] >= 5 },
    },

    msgs => {
        invalid => {
            field => {
                email => 'no valid e-mail address',
                age => 'no valid age between 01 and 99',
                },

                default => 'contains an invalid value',
            },

        missing => 'missing!',
    },

}

这就是我们读取值的方式：

    <tr>
        <td>E-mail address:</td>
        <td><input type="text" name="email" value="[% email %]" />* [% c.form.msgs.email %]</td>
    </tr>

对于缺失的字段，一切正常。对于无效字段，仅打印出赋予 invalid => 的值。如果设置为无效=> “THIS IS INVALID!” 会打印字符串，如果设置为 invalid =>; {} 哈希引用打印为 HASH(0x784d80)（即使是空哈希）。

有人可以解释这是为什么吗？我们使用 CPAN 的 Data::FormValidator 当前版本 4.66。

更新：通过转储[% c.forms %]，我的同事可以验证字段的有效性是否已正确确定。只是字符串设置错误，我们不知道为什么。

We develop a Catalyst app and my coworker started implementing form validation with Catalyst::Plugin::FormValidator which provides a shortcut to Data::FormValidator.

The validation seems to succeed and the display of missing entries works. But when displaying details for mismatched constraints the page contains a hashref like HASH(0x784d80).

This is the hash we use to configure the validator (everything example code made up to test FormValidator first):

{
    required => [qw/email age sex/],
    optional => [qw/city name/],
    filters  => [qw/trim/],

    constraints => {
        name => sub { length $_[1] >= 2 },
        sex => sub  { $_[1] =~ /^(male)|(female)$/},
        age => sub { $_[1] =~ /^[0-9]{1,2}$/ },
        email => sub { Email::Valid->address(lc($_[1])) },
        city => sub { length $_[1] >= 5 },
    },

    msgs => {
        invalid => {
            field => {
                email => 'no valid e-mail address',
                age => 'no valid age between 01 and 99',
                },

                default => 'contains an invalid value',
            },

        missing => 'missing!',
    },

}

This is how we read the values:

    <tr>
        <td>E-mail address:</td>
        <td><input type="text" name="email" value="[% email %]" />* [% c.form.msgs.email %]</td>
    </tr>

For missing fields everything works fine. For invalid fields the value given to invalid => is just printed out. If set to invalid => "THIS IS INVALID!" the string is printed and if set to invalid => {} the hashref is printed as e.g. HASH(0x784d80) (even for empty hash).

Can somebody explain why this is? We use the current version 4.66 of Data::FormValidator from CPAN.

Update: By dumping [% c.forms %] my coworker could verify that the validity of the fields is determined correctly. Just the string is set wrong and we don't know why.

表单验证器选项的 msgs->{invalid} 键是一个哈希值。它是一个字符串：

这是一个更复杂的示例，展示了如何提供您自己的默认消息字符串，以及如何为每个字段提供自定义消息以及处理多个约束：
msgs =>; {
    ...

    # 默认无效消息，默认为“Invalid”
    无效=> '有问题！',

    ...
}

您应该能够在 constraints 键中使用>msgs 每个无效字段错误消息的哈希值：

constraints => {
    'date_and_time' => 'Not a valid time format',
    # ...
}

但是，我目前也在尝试使用约束并且它没有任何效果，因此字段相关错误消息的功能可能不会实际存在。

The msgs->{invalid} key for your form validator options is a hash. It is meant to be a string:

Here's a more complex example that shows how to provide your own default message strings, as well as providing custom messages per field, and handling multiple constraints:
msgs => {
    ...

    # Default invalid message, default's to "Invalid"
    invalid => 'Problematic!',

    ...
}

You should be able to use the constraints key in the msgs hash for per invalid field error messages:

constraints => {
    'date_and_time' => 'Not a valid time format',
    # ...
}

However, I am also currently trying to use the constraints and it is not having any effect, so the feature of field dependent error messages may not actually exist.
