RE: [binarycloud-general] Metabase setup in R2

Hi James,

How I currently deal with it:

[1] I have libs that are dealing with the database interfacing. e.g. a
manager class for managing resources (doing queries, file operations).  This
class imports metabase stuff at the very beginning. e.g.:

r2/binarycloud/user/lib/MgrResources.php:
// {{{
import('user.lib.Exception');
import('user.conf.datasources');
import('ext.metabase.metabase_database');
import('ext.metabase.metabase_interface');
import('ext.metabase.metabase_mcrypt');

class MgrResources {
	function MgrResources() {
		MetabaseSetup etc like described in docs
	}

	function Lister() {}
	function ListById() {}
	function Add() {}
	function Set() {}
	...
};
// }}}

[2] I wrote a module package for managing resources:
r2/binarycloud/user/mod/manage_resources/ consisting of 4 atomic modules
ListResources, DeleteResource, AddResource, EditResource. Those modules are
importing my manager in the constructor and using smarty to generate the
html output.

e.g. (simplified for better illustration)

// {{{
class ListResources {

	var $mgr; //my manager
	var $tpl;  // my template

	function ListResources($_params) {
		import('user.lib.MgrResources');
		import('user.lib.Template'); // includes ext.smarty.stuff

		// doing other stuff, switch(action) or something else

		// aggregation
		$this->mgr =& new MgrResources();
		$this->tpl =& new Template();
		$this->tpl->SetPath(BC_PATH_MOD.'manage_resources/html');

		$result =& $this->mgr->Lister();
		$this->tpl->assign('RESULT', $result);
		return true;
	}

	function Output() {
		$this->tpl->display('list.xhtml');
		return true;
	}
};
// }}}


And that works very good. No, wait: most excellent :-)
