How to emulate has_many :through with polymorphic classes?

Implementing the host method on the Pest class is straight forward. We need to make sure we clear the old host while setting a new host (as AR doesn't clear the old value from the intermediary table.).

You can address your problem by using STI and regular association.

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.
