Answer 1

search http://guides.rubyonrails.org/association_basics.html to better understand rails associations.

user.rb

has_one :profile
has_one :notification
has_one :role

accepts_nested_attributes_for :profile, :notification, :role

You might to put each of the “accepts nested attributes for” on their own line.

The each other model would need:

belongs_to :user

EDIT

form

= form_for @user do |f|

 .field
   f.text_field :name

 .field
   f.text_field :email

 f.fields_for :profile do |t|
   .field
     t.text_field :description

 .actions
   = f.submit

Also, in your controller, make sure to have:

def new
 @user = User.new(profile: Profile.new)
end
