Basic help on what to do with table related classes in the model

hi everyone,

sorry for this noob questions, but I’m really confused about Revo and xPDO - just started devoloping with revo

What I have:
- 4 custom tables in use with a snippet
- xPDO model in core/compentents/mysnippet/model
- snippet code in core/components/mysnippet/elements/snippets/snippet.php
- a general snippet class in core/components/mysnippet/snippet.class.php
- 4 custom table specific classes (e.g. projects.class.php), map files and so on

What I actually wanted:
- the general snippet class should handle general things (get, set for all objects (specified by parameters) etc.)
- the table related classes should contain table specific methods which uses the general snippet methods (e.g. loadpropjects in projects.class.php calls with parameters the loadobject in mysnippet.class.php)

I’m really confused: What are the specific table classes for? Can I use them for what I want? When these classes are initiated: with calling getService(mysnippet.class.php) or with addPackage?

There are a lot more questions, but perhaps some of them are solved by understanding the "big thing" behind

thanks in advance!
Chris

Oh man, we really need docs for stuff like this. It’s swimming in the dark for a lot of people.

I put together this doc after struggling with that sort of thing for a long time:

Hope that helps.
