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 are using wrong method for appending your child with the parent.And also it is has_one relation,so you should use build_model not model.build.Your new and create methods should be like this

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

  def create
    @hotel = current_user.hotels.build(hotel_params)

    if @hotel.save      
      flash[:success] = "Hotel created!"
      redirect_to @hotel
    else
      render 'new'      
    end    
  end

Update

Your hotel_params method should look like this

def hotel_params
   params.require(:hotel).permit(:title, :stars, :room, :price,address_attributes: [:country,:state,:city,:street])
end
