Currently have this:
<sec:ifLoggedIn>
<sec:username/><br/>
<sec:roles/><br/>
<g:link controller="logout" action="index">Logout</g:link>
</sec:ifLoggedIn>
<sec:ifNotLoggedIn>
<h1>Who are you?</h1><br/>
<g:link controller="login" action="auth">LOGIN</g:link>
</sec:ifNotLoggedIn>
Which gives the error:
Tag [roles] does not exist. No tag library found for namespace: sec
However when I remove <sec:roles/><br/>
it works fine. Why is this? This is only a problem in production, on intellij everything is great.
Solución
No tag roles
exists in spring security core plugin. If you want to show user roles in the view then you can create your own tag.
class TestTagLib {
static final namespace = 'myTag'
def springSecurityService
def userAuthorities = { attrs ->
out << springSecurityService.principal.authorities
//or out << springSecurityService.authentication.authorities
}
}
and use it in you view as
<myTag:userAuthorities/>
Otros consejos
According to the documentation for the spring security core Grails plugin, there is no tag "roles". That's why it errors. Intellij likely just ignores this tag completely.
