Rendering Views
We have now seen how to set views to be rendered from our handlers. However, we can use some cool methods to render views and layouts on-demand. These methods exist in the Renderer and several facade methods exist in the super type so you can call it from any handler, interceptor, view or layout.
- 1.
renderView() - 2.
renderExternalView() - 3.
renderLayout()
<cfoutput>
// render inline
#renderView( 'tags/metadata' )#
// render from a module
#renderView( view="security/user", module="security" )#
// render and cache
#renderView(
view="tags/longRendering",
cache=true,
cacheTimeout=5,
cacheProvider="couchbase"
)#
// render a view from the handler action
function showData(event,rc,prc){
// data here
return renderView( "general/showData" );
}
// render an email body content in an email template layout
body = renderlayout( layout='email',view='templates/email_generic' );
</cfoutput>
Inline renderings are a great asset for reusing views and doing layout compositions
If you need rendering capabilities in your model layer, we suggest using the following injection DSL:
property name="renderer" inject="provider:coldbox:renderer";
This will inject a provider of a Renderer into your model objects. Remember that renderers are transient objects so you cannot treat them as singletons. The provider is a proxy to the transient object, but you can use it just like the normal object:
function sendEmail(){
// code here.
var body = renderer.renderView( "templates/email" );
}
