[Support nested urls for nested modules] #twill

twill-nested-module-urls.md

By default Twill will disply the url of a module item to be {siteurl}/{module}/{slug} e.g. mysite.com/pages/about. With the 'about' section being the editable slug. This is understandable as Twill knows nothing of your frontend routing. However it is likely confusing for editors, as that url presented will not be the final url of the content.

Remove module name form url

This will give us more correct urls e.g. mysite.com/about

// app/Http/Controllers/Admin/PageController

	protected $permalinkBase = '';

Allow for nested pages to have correct urls

To achieve this we need to set permalinkBase dynamically with a function.

// app/Http/Controllers/Admin/PageController

	protected $permalinkBase = '';

	public function __construct(Application $app, Request $request) {
        parent::__construct($app, $request);

        $this->permalinkBase = $this->getPermalinkBase($request);
    }


	protected function getPermalinkBase($request) {
        $param = strtolower($this->modelName);
        $id = $request->route($param);
        
      	if( !$id ) {
            return  $this->permalinkBase;
        }

        $item = $this->repository->getById($id);
        if( !$item->isRoot() ) {
            $permalinkBase = '';
            $ancestors = $item->ancestors()->with('slugs')->get();
            foreach($ancestors as $ancestor) {
                $permalinkBase .= '/'. $ancestor->slug;
            }
            //remove first slash and return
            return substr( $permalinkBase . $this->permalinkBase, 1);
        } else {
            return  $this->permalinkBase;
        }
    }
