Hi,

I’m a Ruby on Rails newbie. I’ve been tasked with building our = office’s first ROR application, and I am the only one working on it, so I am = muddling through with a couple of books… Moving along slowly but need = some discussion time with some people who KNOW it and can maybe offer some = answers to questions I haven’t found in my books.

First = – what is the fundamental difference between “render” and = “redirect_to” when working with .rhtml forms in the Controller? When is it = appropriate to use these?

Second = - Why do I sometimes have to use a while loop to access my queried data in the = .rhtml form? Example:

Controller-Edit Method

@edit =3D Cause.find(:all, :conditions =3D> = "case_id =3D '#{@caseid}'")

View-Edit.rhtml

<h2>Editing Case <%=3D @edit.case_id = %>

This = method of data retrieval has worked for me in other similar forms, and I = can’t figure out why it won’t work here. The error it gives is = that case_id is not a valid method, but it is a valid field in the table, so should = work. (case_id is the foreign key for the table)

However, if I put the data retrieval inside a while loop, it displays the data, but = gives me a routing error when I try to update.

I have = other questions as well, but I guess I’ll start here. ANY AND ALL = tips, advice, etc. would be greatly appreciated!!

Thank = you,
