renderNothing()

Signature

renderNothing() — returns void

Available in: controller Category: Rendering Functions

Description

Instructs the controller to render an empty string when it’s finished processing the action. This is very similar to calling cfabort with the advantage that any after filters you have set on the action will still be run.

Parameters

Name	Type	Required	Default	Description
status	string	no	[runtime expression]	Force request to return with specific HTTP status code.

Examples

// 1. Render a blank response (useful for AJAX fire-and-forget actions)
renderNothing();

// 2. Render a blank response with a specific HTTP status code (e.g., 204 No Content)
renderNothing(status=204);

// 3. Use renderNothing() instead of cfabort so that after-filters still run
// In a controller action:
function markAsRead() {
    post = model("Post").findByKey(params.key);
    post.update(read=true);
    // After-filters (e.g. logging) will still execute, unlike cfabort
    renderNothing();
}
