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

Bottom line here is you need to use the f.fields_for method correctly.

Controller

There are several things you need to do to get the method to work. Firstly, you need to build the associated object, then you need to be able to pass the data in the right way to your model:

#app/models/hotel.rb
Class Hotel < ActiveRecord::Base
   has_one :address
   accepts_nested_attributes_for :address
end

#app/controllers/hotels_controller.rb
Class HotelsController < ApplicationController
    def new
       @hotel = Hotel.new
       @hotel.build_address #-> build_singular for singular assoc. plural.build for plural
    end

    def create
        @hotel = Hotel.new(hotel_params)
        @hotel.save
    end

    private

    def hotel_params
        params.require(:hotel).permit(:title, :stars, :room, :price, address_attributes: [:each, :address, :attribute])
    end
end

This should work for you.

Form

Some tips for your form - if you're loading the form & not seeing the f.fields_for block showing, it basically means you've not set your ActiveRecord Model correctly (in the new action)

What I've written above (which is very similar to that written by Pavan) should get it working for you
