Resolves a message from the given code or error. Normally used in conjunction with eachError. O


Loop through each error and output the message:

<g:eachError bean="${book}">
    <li><g:message error="${it}" /></li>

Note that this is typically used for built-in Grails messages, rather than user application messages. For user application messages, use the code or message parameters, as illustrated below.

Output a message for a specific known code:

<g:message code="my.message.code" />

Output a message for a compatible object.

<g:message message="${myObj}" />

Note that objects passed to the message parameter must implement the org.springframework.context.MessageSourceResolvable interface.



One of either the error attribute, the code attribute or the message attribute is required. Messages are resolved from the grails-app/i18n/ bundle. See also Internationalization.

For a more complex example, to output your own message with parameters and a default message, you might use the following code from your controller:

flash.message = "book.delete.message"
flash.args = [ "The Stand" ]
flash.default = "book deleted"

You would then specify the following in

book.delete.message="Book {0} deleted."

and specify the following from your view:

<g:message code="${flash.message}" args="${flash.args}" default="${flash.default}"/>

Which would result in the output "Book The Stand deleted." If you had misnamed the message or not specified it in, your default message of "book deleted" would be output.
