How to route multiple levels of nested resources in Rails 3?

You can keep nesting the way you have shown and things will work fine. There are quite a few sources that will tell you not to go crazy nesting routes though. Take a look at Rails Best Practices for example (I think the article was created for rails 2 but the principals still apply).

Jamis Buck also blogged about this a while ago.

Yes, you can keep nesting and nesting and nesting and so forth.

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.
