Examples

Example controller for an application called "shop":

class BookController {
    def list() {
        [books: Book.list(params)]
    }

def show() { [book : Book.get(params.id)] } }

Example usages for above controller:

<g:link action="show" id="1">Book 1</g:link>

<g:link action="show" id="${currentBook.id}">${currentBook.name}</g:link>

<g:link controller="book">Book Home</g:link>

<g:link controller="book" action="list">Book List</g:link>

<g:link controller="book" action="list" plugin="publishingUtils">Book List</g:link>

<g:link url="[action:'list',controller:'book']">Book List</g:link>

<g:link action="list" params="[sort: 'title', order: 'asc', author: currentBook.author]"> Book List </g:link>

<g:link controller="book" absolute="true">Book Home</g:link>

<g:link controller="book" namespace="publishing">Publishing Book Home</g:link>

<g:link controller="book" base="http://admin.mygreatsite.com">Book Home</g:link>

Example as a method call in GSP only:

<%= link(action:'list',controller:'book') { 'Book List' }%>

Results in:

<a href="/shop/book/list">Book List</a>
