Hi John,
so you mean the variant with less relations. Only have a relation once?
Can you tell me why? Would it make a difference performance wise?
If I also want to include in the model series post type all the available models which exist for that series, how would I do that?
Do I need to use the post2post plugin? There was written the field needs to have the same name on both posttypes? Can you give me an example for this case, I mean how would you name that field. ModelModelseries or something?
