I am trying to pass from my controller to my view in grails In my controller i have this:

    def index() {
    def user = User.get(springSecurityService.principal.id)
    def children = user.children
    }

and in my gsp (view i have this)

 <g:each var="child" in="${children}">
    <p>Name: ${child.firstname}</p>
    <p>Author: ${child.lastname}</p>
 </g:each>

By convention, Grails will render the view that matches the controller action that was executed. It will also, by convention, pass as the return value of the action as the view's model. In your case for this to work correctly, you can either explicitly render the view as in @Mr. Cat's answer, or you can return the model like

def index() {
    def user = User.get(springSecurityservice.principal.id)
    [children: user.children]
}

Groovy implicitly returns the last expression evaluated.

Try this:

def index() {
   def user = User.get(springSecurityService.principal.id)
   render(view:'index',model:[children:user.children]) 
}
