Grails自定义错误消息的问题 [英] Grails Problem with custom error messages

问题描述

我目前正在尝试在默认约束条件下为grails指定自定义错误消息，但到目前为止，我所得到的都是默认错误消息。

我知道我必须编辑grails-app / i18n / messages.properties文件

如果更改以下默认错误代码消息，它将正确显示新的错误消息

  default.blank.message =类[{1}]的属性[{0}]不能为空
  

然而，这不是我想要做的。我需要更详细的错误报告，并且有多个字段可以是空白的。我希望能够做到的是为类中的每个字段显示自定义消息。

  package com.mycompany.myapp 
 
 class Test {
 
字符串名称
 def constraints = {
名称（可空：假，空白：假）
} 
} 
  

（在messages.properties结尾附加代码）

  test.name.blank =名称不能为空
 test.name.nullable =名称不能为空
  

根据grails文档，这应该可以正常工作，有或没有包名 - className.propertyName.blank

grails.org/doc/latest/（约束部分）& （第7.4节 - 验证和国际化）

我尝试了所有我能想到的组合，但它总是显示自定义消息

我也尝试安装grails i18n模板插件

http://www.grails.org/I18n+Templates+Plugin

自动生成错误代码我。我将新的错误代码添加到现有messages.properties文件的末尾，但仍然收到了默认错误消息。

但是，错误代码有些不同这是由插件生成的。

代替了grails doc中指定的格式 - test.name.null = ......，它会自动生成测试。 name.null.error = Custom Message

我也尝试完全删除默认错误消息，但仍显示

如果有人遇到过这个问题，我将不胜感激任何人都可以给我的帮助

预先感谢

解决方案

将def messageSource（在控制器或服务中）

  item。错误？.allErrors？.each {
 println messageSource.getMessage（it，null）
}; 
  

我还找到了一个很好的链接，可以更好地解释这一点。

I am currently trying to specify custom error messages in grails for the default constraints but so far all I get back is the default error message.

I know that I have to edit the grails-app/i18n/messages.properties file

If I change the following default error codes message, it will correctly display the new error message

default.blank.message=Property [{0}] of class [{1}] cannot be blank

However, this is not what I am trying to do. I need more granular error reporting and have more than one field that can be blank etc. What I would like to be able to do would be, display custom messages for each field in a class

package com.mycompany.myapp

class Test{

 String name
 def constraints = {
 name(nullable:false, blank:false)
 }
}

(following codes appended to end of messages.properties)

test.name.blank=Name cannot be blank
test.name.nullable=Name cannot be nullable

According to the grails documentation this should work correctly, either with or without the package name - className.propertyName.blank

grails.org/doc/latest/ (constraints section) & (section 7.4 - validation & internationalization)

I have tried all comnbinations that I can think of, but it always displays the custom message

I have also tried installing the grails i18n templates plugin

http://www.grails.org/I18n+Templates+Plugin

which generated the error codes automatically for me. I appended the new error codes to the end of the existing messages.properties file but I still get the default error messages.

However, there was something different with the error codes that were generated by the plugin.

instead of the format specified in the grails doc - test.name.null=......, it automatically generated test.name.null.error=Custom Message

I have also tried deleting the default error messages completely, but they are still displayed

If anyone has experienced this issue before, I would appreciate any help that anyone can give me

Thanks in advance

解决方案

put def messageSource (in controller or service)

item.errors?.allErrors?.each{ 
println  messageSource.getMessage(it, null)
};

I also found a good link which explains this better
