Question

I have the following DB relations:

Building hasMany Shape

Appartment hasOne Shape

Building hasMany Appartment

Shape belongsTo Building & Appartment

Now, in the Shape model I would like to retrieve all shapes belonging to a certain building. This includes the shapes belonging to the appartments belonging to this certain building.

E.g.

Building 'X'

There are 4 shapes directly linked to building X via the belongsTo Building relation.
Shape->Building

And there are 2 shapes directly linked to 2 appartments via the belongsTo Appartment relation. These 2 appartments again are directly linked to Building X via the belongsTo Building relation. Thus these 2 shapes are indirectly linked to building X.
Shape->Appartment->Building

I can’t seem to get my head around this, help is much appreciated.
