Nested model form Attributes not working

Question

I have a index page(simple scaffold generated listings) that list all ads. I have made so that when I click on a ad it will expand(css and jquery) and show the information on that ad. Now the problem that I cant get to work is that I want to be able to book that ad through a form inside of the index ads_item views.

and to get clear so that we are on the same page here is a mockup on what I am doing

The error i get is

param is missing or the value is empty: ads_item

This is what I got

routes

  resources :ads_items do
    resources :bookings
  end

ads_items controller

def new
    @ads_item = AdsItem.new
end

def create
    @ads_item = AdsItem.new(ads_item_params)

    respond_to do |format|
      if @ads_item.save
      format.html { redirect_to @ads_item, notice: 'Ads item was successfully created.' }
      format.json { render :show, status: :created, location: @ads_item }
  else
      format.html { render :new }
      format.json { render json: @ads_item.errors, status: :unprocessable_entity }
    end
  end
end

bookings controller

def new

  @booking = Booking.new

end

def create
  @booking = Booking.new(booking_params)

  respond_to do |format|
    if @booking.save
      format.html { redirect_to @booking, notice: 'Booking was successfully created.' }
      format.json { render :show, status: :created, location: @booking }
    else
      format.html { render :new }
      format.json { render json: @booking.errors, status: :unprocessable_entity }
    end
  end
end

Model ads_item

class AdsItem < ActiveRecord::Base
  belongs_to :user
  has_many :bookings
  accepts_nested_attributes_for :bookings
end

Model booking

class Booking < ActiveRecord::Base
  belongs_to :ads_item
end

database

create_table "ads_items", force: true do |t|
    t.integer  "user_id"
    t.date     "date"
    t.time     "time"
    t.string   "type_of_service"
    t.string   "address"
    t.text     "include_in_price"
    t.integer  "rate"
    t.integer  "original_price"
    t.integer  "now_price"
    t.boolean  "booked"
    t.string   "category"
    t.datetime "created_at"
    t.datetime "updated_at"
    t.string   "company_information"
    t.string   "company_website"
    t.string   "company_facebook"
    t.string   "company_twitter"
    t.string   "company_instagram"
    t.string   "company_google_maps"
    t.string   "company_phone"
    t.string   "company_name"
    t.string   "logo_path"

end


create_table "bookings", force: true do |t|
    t.string   "first_name"
    t.string   "last_name"
    t.string   "social_nr"
    t.string   "phone_nr"
    t.string   "email"
    t.integer  "ads_item_id"
    t.datetime "created_at"
    t.datetime "updated_at"
end

and the ads_items index view where is list all the items (scaffolded)

<% @ads_items.each do |ads_item| %>
   list all items


  <%= form_for :booking do |f| %>
    <%= f.text_field :first_name %>
    <%= f.text_field :last_name %>
    <%= f.text_field :social_nr %>
    <%= f.text_field :phone_nr %>
    <%= f.text_field :email %>
    <%= f.number_field :ads_item_id, :value => ads_item.id %>                          

    <%= f.submit %>


  <% end %>
<% end %>

I did follow this Rails guide

but it won't work. Am I missing something here ? how do I render the form so that it will get the ads id and save it to the booking table after I filled out the form ?

Answer 1

What you have done so far looks correct. You can use the nested attributes feature in rails to create a booking through the AdItem model, have a look at the documentation here http://api.rubyonrails.org/classes/ActiveRecord/NestedAttributes/ClassMethods.html

You would use the fields_for method in your view to render the booking form.
