Ruby on Rails Saving in two tables from one form

Question

I have two models Hotel and Address. Relationships are:

class Hotel
  belongs_to :user
  has_one    :address
  accepts_nested_attributes_for :address
         


        

Answer 1

You should not build address again

class HotelsController < ApplicationController
  def new
    @hotel = Hotel.new
  end

  def create
    @hotel = current_user.hotels.build(hotel_params)
    # address = @hotel.address.build 
    # the previous line should not be used
    if @hotel.save      
      flash[:success] = "Hotel created!"
      redirect_to @hotel
    else
      render 'new'      
    end    
  end
