|
<p>When implementing <a href="../../db/obj/" class="ref">Virtual Source Objects</a> it's important
|
|
that you can locate them. While virtual sources do not appear as children of
|
|
pages they can be navigated to through the database pad. This is achieved
|
|
through custom virtual path resolvers.</p>
|
|
<p>Each source object needs to be a unique prefix which identifies all instances
|
|
of it. For instance if you want to implement a special page (like a feed)
|
|
that would exist for specific pages, then you can register the virtual path
|
|
prefix <code>feed</code> with your plugin. Though you should use more descriptive names
|
|
for your plugins as these paths are shared.</p>
|
|
<p>If a user then resolves the page <code>/my-page@feed</code> it would invoke your URL
|
|
resolver with the record <code>my-page</code> and an empty list (rest of the path
|
|
segments). If they would request <code>/my-page@feed/recent</code> then it would
|
|
pass <code>['recent']</code> as path segments.</p>
|
|
<h2 id="example">Example</h2><p>Here an example that would implement a virtual source for feeds and an
|
|
associated virtual path resolver:</p>
