(Quick Reference) # form ## Purpose Creates a form that submits to a controller, action, and/or id. Beyond what is described below, all the usual HTML attributes apply. ## Examples Example controller for an application called "shop":

    class Book {
        def list() {
            [books: Book.list(params)]
        }    def show() {
            [book: Book.get(params.id)]
        }
    }
Example usages for above controller:

    <g:form name="myForm" action="myaction" id="1">...</g:form>
    results in:
    <form action="/shop/book/myaction/1" method="post"
          name="myForm" id="myForm">
    …
    </form><g:form name="myForm" url="[action:'list',controller:'book']">...</g:form>
    results in:
    <form action="/shop/book/list" method="post" name="myForm" id="myForm">
    …
    </form><g:form action="show">...</g:form>
    results in:
    <form action="/shop/book/show" method="post" >...</form>
