This may be a silly question.
I am creating my content classes and while normalizing I realized that there is no mention of how to create joins when extracting data from multiple content classes with a object relation between them.

If I had for example a set of songs in one content class which have a reference to the artist name in another content class, how would I get the artist name from the song.

Thx

Hi,

I'm building a web site for my band mysleft (Yes I play in a band ;), and I solved the issue with this extension http://ez.no/community/contribs/datatypes/enhanced_objectrelation

See the trick at the bottom (reverse related), that's probably what you're looking for.

Tell us when your site is live.

Good luck.
