Accessing an attribute of a linked model in Rails

So, sorry if this doesn't come across coherently... I don't know all my Ruby / Rails terminology (yet).

I have a model called "Profile" and a model called "User, and the two are linked like this:

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

Now, in the "index" and "show" views of profiles that I made, I want to be able to access the attribute "nam开发者_StackOverflow社区e" from the User model. How can I do this? I imagine I'll need something in the controller that looks like this:

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

And then access it in the view like this:

<%= @user.name %>

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

Thanks for the help.

If the attribute name belongs to the Profile model, in your view:

<%= @user.profile.name %>

If the attribute name belongs to the User model, please stop the server, run rake db:migrate to be sure every migration has been applied to your database; then run rails console or ruby script/console to check if the attribe is working for your model:

> u = User.first
> u.name

If the last command returns an empty string or the name of your first user, everything is working. If you get a NoMethodError: undefined method you should check your database as the column that should handle the name attribute is probably missing.

Your controller should work. That part is correct.

a few questions

Does your profile have a user_id ?

Did you run a migration that created attributes user_id for Profile and profile_id for User ?
