class BookController {
def list() {
[books: Book.list(params)]
}
def show() {
[book: Book.get(params.id)]
}
}include
Purpose
Includes the response of another controller/action or view in the current response
|
The g:include tag will not generate a separate request. The response from the include action will be merged into the response for the original request.
|
Examples
Example controller for an application called "shop":
Example usages for above controller:
<g:include action="show" id="1" />
<g:include action="show" id="${currentBook.id}" />
<g:include controller="book" />
<g:include controller="book" action="list" />
<g:include action="list" params="[sort: 'title', order: 'asc',
author: currentBook.author]" />Example as a method call in a controller, tag library or GSP:
def content = g.include(action: 'list', controller: 'book')If using nested includes with params it is advisable to use unique parameter names as they are all attached to the same web request.
<g:include controller="outer" action="list" params="[outerPage:1, outerSize:5]"/>
<g:include controller="inner" action="list" params="[innerPage:2, innerSize:10]"/>If non-unique names are used like the following
<g:include controller="outer" action="list" params="[page:1, size:5]"/>
<g:include controller="inner" action="list" params="[page:2, size:10]"/>request.params will contain a list params.page=[2,1] and params.size=[10,5]
