Ransackは簡単にセットアップでき、既存のRailsアプリケーションに統合しやすいです。
シンプルな構文を使用して検索フォームを作成し、モデルのクエリを生成できます。
また、Ransackはカスタマイズが容易です。
検索フォームのデザインや検索条件、ソートオプションなどを自由に調整できます。
カスタムの検索ロジックを実装することもできます。
まずはGemFileにgemの記述を追加します。
gem 'ransack', '~> 4.1', '>= 4.1.1'
バンドルします。
コマンド
bundle
モデル
「app/models/room.rb」ファイルの25行目に以下の記述を追加します。
def self.ransackable_attributes(auth_object = nil) ["accommodate", "active", "address", "bath_room", "bed_room", "created_at", "home_type", "id", "id_value", "is_air", "is_heating", "is_internet", "is_kitchen", "is_tv", "latitude", "listing_name", "longitude", "price", "room_type", "summary", "updated_at", "user_id"] end
記述追加 【app/models/room.rb】25行目
class Room < ApplicationRecord belongs_to :user has_many :reservations has_many :guest_reviews has_many :reviews has_many_attached :photos has_rich_text :description geocoded_by :address after_validation :geocode, if: :address_changed? validates :home_type, presence: true validates :room_type, presence: true validates :accommodate, presence: true validates :bed_room, presence: true validates :bath_room, presence: true def average_rating guest_reviews.count == 0 ? 0 : guest_reviews.average(:stars).round(2).to_i end def self.ransackable_attributes(auth_object = nil) ["accommodate", "active", "address", "bath_room", "bed_room", "created_at", "home_type", "id", "id_value", "is_air", "is_heating", "is_internet", "is_kitchen", "is_tv", "latitude", "listing_name", "longitude", "price", "room_type", "summary", "updated_at", "user_id"] end end
コントローラー
コントローラーを編集します。
記述追加 app\controllers\pages_controller.rb
「search()」メソッドの実装
class PagesController < ApplicationController def home @rooms = Room.where(active: true).limit(6) end def search # ステップ 1 if params[:search].present? && params[:search].strip != "" session[:loc_search] = params[:search] end arrResult = Array.new # ステップ 2 if session[:loc_search] && session[:loc_search] != "" @rooms_address = Room.where(active: true).near(session[:loc_search], 5, order: 'distance') else @rooms_address = Room.where(active: true).all end # ステップ 3 @search = @rooms_address.ransack(params[:q]) @rooms = @search.result @arrRooms = @rooms.to_a # ステップ 4 if (params[:start_date] && params[:end_date] && !params[:start_date].empty? && !params[:end_date].empty?) start_date = Date.parse(params[:start_date]) end_date = Date.parse(params[:end_date]) @rooms.each do |room| not_available = room.reservations.where( "(? <= start_date AND start_date <= ?) OR (? <= end_date AND end_date <= ?) OR (start_date < ? AND ? < end_date)", start_date, end_date, start_date, end_date, start_date, end_date ).limit(1) if not_available.length > 0 @arrRooms.delete(room) end end end end end
ルート設定
ルートの設定をします。
記述追加 config\routes.rb
「get 'search', to: 'pages#search'」の記述を追加（12行目）
Rails.application.routes.draw do # ルートを app\views\pages\home.html.erb に設定 root 'pages#home' # get get 'pages/home' get '/dashboard', to: 'users#dashboard' get '/users/:id', to: 'users#show', as: 'user' get '/your_trips', to: 'reservations#your_trips' get '/your_reservations', to: 'reservations#your_reservations' get 'search', to: 'pages#search' # post post '/users/edit', to: 'users#update' resources :rooms, except: [:edit] do member do get 'listing' get 'pricing' get 'description' get 'photo_upload' get 'amenities' get 'location' get 'preload' get 'preview' delete :delete_photo post :upload_photo end resources :reservations, only: [:create] end resources :guest_reviews, only: [:create, :destroy] resources :host_reviews, only: [:create, :destroy] # device devise_for :users, path: '', path_names: {sign_up: 'register', sign_in: 'login', edit: 'profile', sign_out: 'logout'}, controllers: {omniauth_callbacks: 'omniauth_callbacks', registrations: 'registrations'} # Define your application routes per the DSL in https://guides.rubyonrails.org/routing.html # Reveal health status on /up that returns 200 if the app boots with no exceptions, otherwise 500. # Can be used by load balancers and uptime monitors to verify that the app is live. get "up" => "rails/health#show", as: :rails_health_check # Defines the root path route ("/") # root "posts#index" end

「app\assets\images」フォルダに「home」フォルダを新規作成してください。作成した「home」フォルダの中に何でも良いのでホームページの背景画像となる「background01.jpg」ファイルをコピーして下さい。
「app/assets/stylesheets/application.scss」ファイルに記述を追加します。
//ホームページ用 .has-bg-img { background: url("/assets/home/background01.jpg") center center; background-size: cover; }
記述追加 【app/assets/stylesheets/application.scss】54行目
/* * This is a manifest file that'll be compiled into application.css, which will include all the files * listed below. * * Any CSS (and SCSS, if configured) file within this directory, lib/assets/stylesheets, or any plugin's * vendor/assets/stylesheets directory can be referenced here using a relative path. * * You're free to add application-wide styles to this file and they'll appear at the bottom of the * compiled file so the styles you add here take precedence over styles defined in any other CSS * files in this directory.
