unless

Purpose

The logical unless tag renders its body conditionally, based on an expression and/or current environment. The unless tag will render its body unless all of the specified conditions (test and/or environment) are true. The tag will always do the opposite of what the if tag would have done.

Examples

<g:unless test="${name == 'fred'}">
     Hello ${name}!
</g:unless>
<g:unless env="development">
     Dev mode - debug: $someDebug
</g:unless>
<g:unless env="production" test="${cacheEnabled}">
     $cache.getContent('1234')
</g:unless>
