Removing Elements From The View Cache

Introduction

If you use any of the view partial caching mechanisms in Coldbox either through setView() or renderView() you might be asking yourself:

Is there an easy, programmatic way to remove a specific element from the view cache?

The answer is, of course! All view and event caching occurss in a cache provider called template and you can retrieve it like so from your handlers, layouts, views, plugins and interceptors:

var cache = getColdBoxOCM("template");
var cache = cachebox.getCache("template");

You can also use the WireBox injection DSL

property name="cache" inject="cachebox:template">

clearing methods

There are a few methods that will help you clear views:

• clearView(viewSnippet) - Clear views with a snippet
• clearAllViews(async) - Clear all views
• clearViewMulti(viewSnippets) - Clear multiple view snippets with a list or array of snippets

getColdboxOCM('template').clearView('home');

Very easy! Just send in what you need and it will be purged.
