Accessing the attribute of a related model in Rails

Question

So, sorry if this does not occur coherently ... I don't know all my Ruby / Rails terminology (yet).

I have a model called "Profile" and a model called "User" and they are connected as follows:

class Profile < ActiveRecord::Base
belongs_to :user
class User < ActiveRecord::Base
has_one :profile

Now, in the index and show views of the profiles that I created, I want to have access to the name attribute from the user model. How can i do this? I assume that I will need something in the controller that looks like this:

class ProfilesController < ApplicationController
  def show
    @user = User.find(params[:user_id])

And then enter it in the form as follows:

<%= @user.name %>

But this bit of code doesn't work right there.

Thanks for the help.
