How do you nest g:each tags in gsp?

grails, gsp

Solution

If you want to display all books by author you could have something like

<g:each var="author" in="${Author.list()}">
    <p>Author: ${author.fullName}</p>
    <ul>
    <g:each var="book" in="${author.books}">
        <li>${book.title}</li>
    </g:each>
    </ul>
</g:each>

Cheers!

Problem

Assume I have the following classes ``` class Genre { static hasMany=[author:Author] } class Author{ static hasMany=[books:Books] } class Books{ Author author } ``` How do I go about printing this in the gsp using g:each tag?
