How to store an Array of IDs?

[Christoph Blank]

Hi there,

I have a Property object that has a lot of Items as children, however, the method property.items builds a list

of all subitems based on calculations. Since this is an expensive and recursive operation in my example, I have to cache these IDs

and update them with a hook.

What is the best way to store an array of IDs (Strings) in Datamapper (I only have mysql) which could eventually also

be used in a query? (included_in <list>)?

Thanks,

Christoph
