Hello.

I have the following:

I have a Entity called WG, and one called, TRANSLATIONSET. so the relationship is WG << >> TRANSLATIONSET.

if I have the wg , I want to get all the TRANSLATIONSET that this partigual wg has. Whne I was definiyng the EOModel, I set up a manytomany relationship with a join table called WGxTS and I unchecked the Flattern box, I read it somewhere.

If all the WGxTS table is doing is being a join table for a many-to- many relationship, then flattening it I believe is the right thing to do.


so if I do.

NSArray aux = wg.toTranslationSets();

If you don't do flattening, then you'd need something along the lines of: wg.toTranslationSets().valueForKey("TranslationSet")


Dave

the contents of aux are all what is in the WGxTS which is not more than the pk of WG and TRANSLATIONSET related..

What am I missing here, this is the first time Im working with many- to-many rs.


Thanks in advance

Gustavo
