Decent .AsTernaryAssociation() documentation

[Francois Botha]

Hi all,

I search this list and StackOverflow and nowhere could I get a good, solid explanation of exactly how .AsTernaryAssociation() works. Lots of posts that I did find have conflicting statements. My guess is that the implementation of ternary associations evolved over time.

I'd appreciate it if someone can post a simple example and explanation of a ternary association (please pre-test your code), and a bonus would be to explain the finer tweaks that are possible. In return, I will consolidate all your feedback and compile a page for the Fluent NHibernate Wiki on this subject.

Some questions I have around .AsTernaryAssociation() :

• Is .AsMap() required or is it ignored? 
• If it's used, what does .AsMap(null) imply (found that in some posts)?
  
• How does HasMany(x => x.stuff).AsTernaryAssociation() vs HasManyToMany(x => x.stuff).AsTernaryAssociation()  work? What's the difference?
• For a many-to-many ternary association, is the HasManyToMany statement required from all sides (i.e. in all classes)?
• It seems the default many-to-many table name is KeyValuePair`2ToMyClassName. I can override it with .Table() but is that by design or did I do something wrong?

Or feel free to add anything else.

thanks,

Francois

Best documentation is the code.

Already tried that and failed. But you're welcome to prove me wrong.

I'm afraid the code is terrible, and this functionality is completely unknown to me. It's something that needs to be killed/rebuilt, but I haven't had any volunteers (and don't use the functionality myself).
