Do has_many :through associations work for models that only exist in memory?

I guess that object a has no reference to object c created. Normally it would run a query, but it won't since it is not saved to db. I think that it is created for db relations and it just doesn't check references to in-memory objects You can also try this: a = A.

New a.cs. Build a. Bs => but a.Cs => created c object.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
