Reading an existing mongo database?

I've tried mongomapper after having tried mongoid, and it does exactly what it's name implies.

It depends on what the existing database contains and what you want to do with it. If it just contains some raw data that isn't specific to Rails, you can use the generic ruby driver to do raw queries to the database.

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.
