MODEL class User < ActiveRecord::Base   has_one :address, :dependent => :destroy   accepts_nested_attributes_for :address end

CONTROL   def new     @user = User.new     @user.build_address # Adicionei   ...

VIEW partial _form .... <% f.fields_for :address do |b| %> # Adicionei     <%= b.text_field :city_manual %> # Adicionei <% end %> # Adicionei ....

So this is not working... when browser to users/new it do not show the field as should... Change this to a has_many all works. Using has_one this make me crazy and not work... anyone help?

Sorry, I don't have an answer for you on this. But I'm curious -- why are you putting the address in a separate model if you are using has_one? It seems like an over-normailization to me. Why not just put those attributes in the user and be done with it?

Model address has 8 attributes... i did it to minimize user table size.

About the problem... just try in your machine you will se it not workin as should do.

in your

def new

try @user.address = Address.new

5

The result is the same... the field do not show in view when browsing to /users/new

Just tested. Everything works fine.

Make sure:

1) you didn't forget to put "belongs_to :user" association in your Address model 2) use "<%=" for your "f.fields_for :address" in the _form view file.

Hope this helps.
