The Grails Framework 3.2.8

(Quick Reference) ## message ### Purpose Resolves a message from the given code or error. Normally used in conjunction with eachError ### Examples Loop through each error and output the message:
    <g:eachError bean="${book}">
        <li><g:message error="${it}" /></li>
    </g:eachError>
| 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="${myObj}" />
| Objects passed to the message parameter must implement the MessageSourceResolvable interface.
### Description Attributes `error` (optional) - The error to resolve the message for. Used for built-in Grails messages. `code` (optional) - The code to resolve the message for. Used for custom application messages. `message` (optional) - The object to resolve the message for. Objects must implement `MessageSourceResolvable`. `default` (optional) - The default message to output if the error or code cannot be found in `messages.properties`. `args` (optional) - A list of argument values to apply to the message when `code` is used. `encodeAs` (optional) - The name of a codec to apply, i.e. HTML, JavaScript, URL etc `locale` (optional) Override `Locale` to use instead of the one detected One of either the `error` attribute, the `code` attribute or the `message` attribute is required. Messages are resolved from the `grails-app/i18n/messages.properties` bundle. See also Internationalization. For a more complex example, to output your own message with parameters and a default message, you might use the following code from your controller:
    flash.message = "book.delete.message"
    flash.args = ["The Stand"]
    flash.default = "book deleted"
You would then specify the following in messages.properties:
    book.delete.message="Book {0} deleted."
and specify the following from your view:
    <g:message code="${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 `messages.properties`, your default message of "book deleted" would be output. | Quick Reference (hide)
