A module should let the core know if it supports categorization and on which Doctrine Entities

[tfotis]

During the Categories refactoring to Doctrine 2, i came upon some issues regarding Category registry that need to be dealt with in the future.

First of all, not all modules support categorization, but in Category registry -> Choose module, the user can see all the installed modules. This is bad usability. So in order to solve this, a module should let the core know if indeed it supports categorization. If it does, it will be listed inside the select box. If it doesn't, it will not.

Second, not all entities of the module support categorization, but in Category registry -> Choose entity, the user can see all entities of the module. bad usability again. The module should let the core know, which of it's entities support categorization. If they do, they will be listed inside the select box.

a very good idea. +1

I wonder if there might be a way to generate the information based on scanning the entities?

This would be a good usecase for module capabilities (defined in Version). Meta data can be stored in there too...

$modversion['capabilities'] = array('categorisable' => array('version' => '1.0', entities => 'comma list of entites')); 

Just a thought. It's not something we need to deal with right at this point as there is a LOT of other structural stuff to do meantime.

I believe this was complete in Core-1.4.0
