one-to-one relation in Rails

I'm trying to achieve a simple 1 to 1 relation in Rails 3 where a user can connect a bank account.

class User < ActiveRecord::Base
  has_one :bank
  accepts_nested_attributes_for :bank
  attr_accessible :bank_attributes
end

class Bank < ActiveRecord::Base
   belongs_to :user
end

Route

resources :users do
  resources :bank

Now when i build a new bank object for a user in users/1/bank/new like this:

def new
  @user = User.find(current_user.id)
  @bank = @user.build_bank
end

I get an error on my for which looks like this:

<%= simple_form_for(@bank) do |f| %>

The error is:

undefined method `banks_path' for #<#<Class:0x007fa7bd090f08>:0x007fa7c0545b40>

My goal is to have a separate form for a user to add there bank account information.. Hope someone can help me in the right direction to do this. I also use ActiveAdmin and the relation with forms etc works fine there.

Any help is appreciated!

You need to declare resource in plural form regardless of the association type.

So, your resource declaration 

resources :users do
  resource :banks
end

Since bank is nested under user, you need to give the user to the form:

<%= simple_form_for([@user, @bank]) do |f| %>

In addition, your routes file should be

resources :users do
  resource :bank

This will give you a user_bank_path for a user
