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()

Check out the latest API Docs for the latest arguments:

<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

Model Rendering

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" );

}
