bingung, mohon bantuan. Saya mo tampilkan data yang ada di tabel lain yang
terelasi antar tabel. Berikut Keterangannya :
----------------------------------------------------------
Location : app/models/kamar.rb
----------------------------------------------------------
class Kamar < ActiveRecord::Base
belongs_to :hotel
...
def self.find_all_in_kamar(hotel)
hotel = Hotel.find_by_name(hotel)
self.find :all, :conditions => "id_hotel = #{Hotel.id}"
end
...
----------------------------------------------------------
Location : db/migrate/kamar.rb
----------------------------------------------------------
class CreateKamars < ActiveRecord::Migration
def self.up
create_table :kamars do |t|
t.column :id_hotel, :string, :limit => 8
...
end
execute 'ALTER TABLE kamars ADD CONSTRAINT fk_kamars_hotels
FOREIGN KEY ( id_hotel ) REFERENCES hotels( id ) ON DELETE CASCADE'
...
end
----------------------------------------------------------
Gimana caranya supaya supaya di view/kamar/show.rhtml saya bisa menampilkan
informasi semua data hotel yang memiliki id hotel sesuai dengan id_hotel pada
tabel kamar. Apa yang harus saya tulis di :
class KamarController < ApplicationController
....
def show
@kamar = Kamar.find(params[:id])
?? Apa yang harus saya tulis disini utk menampilkan data hotel??
end
....
