Problem saving associated models

I want to save data from User(parent model) when creating/editing a Shop (child model).

My models: [code]     class User < ActiveRecord::Base       has_one :shop, :dependent => :destroy     end

    class Shop < ActiveRecord::Base       belongs_to :user       accepts_nested_attributes_for :user #!!!!!!!!!!!!     end [/code] My Shop controller: [code]     class ShopsController < ApplicationController         def new             @shop =             #@shop.user = current_user             @shop.build_user         end     end

    def create         @shop =[:shop])

        @shop.user = current_user         respond_to do |format|         if             flash[:notice] = t(:shop_created)             format.html { redirect_to(@shop) }             format.xml { render :xml => @shop, :status => :created, :location => @shop }         else             format.html { render :action => "new" }             format.xml { render :xml => @shop.errors, :status => :unprocessable_entity }         end      end

    end [/code] Shop page: [code]     <% form_for @shop, :html => {:multipart => true} do |f| %>         <%- f.fields_for :user do |user| %>             <%= user.text_field :name, :live => true %>         <% end -%>     <% end -%> [/code]

All examples that I found about saving associated models are when saving from User (parent) N children ( my Shop model). In those cases I understand where define accepts_nested_attributes_for.

My case is inverse.

Q: How can I save User data when submitting on Shop form ?
