Nested Form Not saving rails 4 - ruby-on-rails

Question

I have a problem a week ago with nested form. I have a model called users another Auto and another Perfil. I need that when a user creates a new Auto you can change your perfil data if needed
Please can you help me? We'll be very grateful
Try the following:
user model
class User < ActiveRecord::Base
has_many :autos
has_one :perfil
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
end
Auto model
class Auto < ActiveRecord::Base
belongs_to :user
belongs_to :perfil
accepts_nested_attributes_for :perfil, allow_destroy: true
end
Perfil Model
class Perfil < ActiveRecord::Base
belongs_to :user
has_many :autos
end
Auto Controller
class AutosController < ApplicationController
before_action :set_auto, only: [:show, :edit, :update, :destroy]
def new
#auto = Auto.new
#perfil = #auto.build_perfil
end
def create
#auto = Auto.new(auto_params)
#auto.user_id = current_user.id
#auto.perfil_id = current_user.perfil.id
respond_to do |format|
if #auto.save
format.html { redirect_to #auto, notice: 'Auto was successfully created.' }
format.json { render :show, status: :created, location: #auto }
else
format.html { render :new }
format.json { render json: #auto.errors, status: :unprocessable_entity }
end
end
end
def update
respond_to do |format|
if #auto.update(auto_params)
format.html { redirect_to #auto, notice: 'Auto was successfully updated.' }
format.json { render :show, status: :ok, location: #auto }
else
format.html { render :edit }
format.json { render json: #auto.errors, status: :unprocessable_entity }
end
end
end
private
def set_auto
#auto = Auto.find(params[:id])
end
def auto_params
params.require(:auto).permit(:perfil_id, :marca, :modelo, :año, :user_id, perfil_attributes: [:user_id, :nombre, :rut, :telefono, :direccion])
end
end
Perfil Controller
class PerfilsController < ApplicationController
before_filter :authenticate_user!
def show
current_user.perfil ||= Perfil.new
#perfil = current_user.perfil
end
def update
#perfil = current_user.perfil
respond_to do |format|
if current_user.perfil.update_attributes(perfil_params)
format.html {redirect_to root_path, notice: "Datos Actualizados" }
else
format.html {render action: "show"}
end
end
end
def create
current_user.perfil ||= Perfil.new
#perfil = current_user.perfil
respond_to do |format|
if current_user.perfil.update_attributes(perfil_params)
format.html {redirect_to root_path, notice: "Datos Actualizados" }
else
format.html {render action: "show"}
end
end
end
private
def perfil_params
params.require(:perfil).permit(:user_id, :nombre, :rut, :telefono, :direccion)
end
end
And _form.html.erb
<%= simple_form_for #auto do |f| %>
<div class="form-inputs">
<%= f.input :marca %>
<%= f.input :modelo %>
<%= f.input :año %>
<%= f.simple_fields_for :perfil, current_user.perfil do |p| %>
<%= p.input :nombre %>
<%= p.input :telefono %>
<%= p.input :direccion %>
<% end %>
</div>
<div class="form-actions">
<%= f.button :submit %>
</div>
<% end %>
<%= link_to "Save", autos_path, :class => 'button_submit' %>
Routes.rb
Rails.application.routes.draw do
resources :autos
devise_for :users
resources :perfils, only: [:index,:show, :update , :create]
root 'autos#index'
end

Answer 1

This is almost perfect, just 2 little things will get you going.
1 The fields_for need only have :perfil as the object
<%= simple_form_for #auto do |f| %>
<div class="form-inputs">
<%= f.input :marca %>
<%= f.input :modelo %>
<%= f.input :año %>
<%= f.simple_fields_for :perfil do |p| %>
<%= p.input :nombre %>
<%= p.input :telefono %>
<%= p.input :direccion %>
<% end %>
</div>
<div class="form-actions">
<%= f.button :submit %>
</div>
<% end %>
<%= link_to "Save", autos_path, :class => 'button_submit' %>
2 The controller needs to create the object as the current user
def create
#auto = current_user.autos.new(auto_params)
respond_to do |format|
if #auto.save
format.html { redirect_to #auto, notice: 'Auto was successfully created.' }
format.json { render :show, status: :created, location: #auto }
else
format.html { render :new }
format.json { render json: #auto.errors, status: :unprocessable_entity }
end
end
end
