Rails - Aug 2005 - Dependency input

Hi,

Just trying to figure out the best way to handle dependencies when it 
comes to database input. Say I want to input a book, but it relies on a 
genre, artist and so on. At the moment if it only goes up one layer it 
works well as I am using the redirect_back_or_default method from 
login_generator. But if it were to go up any further it would only go 
down one layer.

Should I just build on session[:redirect_url] and use levels, so 
session[:redirect_url][level + 1] = request.request_uri and on 
redirection it would go from highest number to lowest eliminating the 
levels each time it redirects?

Or does anyone have or know of something that is already available to 
provide this function?

Dylan.

I''m not sure if I understand the question correctly, but if I am, check
out what a friend and I came up with at

http://albert.bagasie.com/RailsTips/JumpBack

it allows you to do whatever it is you want to do and then redirect back 
to the last get request that the app received or some other default action.
