gsp - 你如何嵌套g :each tags in gsp?

Question

假设我有以下类(class)

class Genre {
    static hasMany=[author:Author]
}

class Author{

    static hasMany=[books:Books]
}


class Books{
       Author author 
}

如何使用 g:each 标签在 gsp 中打印此内容？

Answer 1

如果你想按作者显示所有书籍，你可以有类似的东西

<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>

干杯!
