Hi there,
you'll have to forgive me, this is my first core data application, so
this could be a uber n00b question.
I need to have an entity which is unique using a compound key. As an
example, an article to a tag. Each article can have many tags, and
thus each tag can have many articles, however, each article can only
have each tag once, and since the interface isn't build on bindings
(all system generated tags) I'd want to leave sqlite to the key
management.
I'm expecting there to be loads of articles and tags, so i always
have scaling in mind.
Whilst I could develop a compound key checker into the model itself,
I was wondering if there were any existing models or settings
available to models to allow this to happen automagically
thanks!
