「app\controllers\rooms_controller.rb」ファイルを更新します。


記述追加　app\controllers\rooms_controller.rb
76行目に「, :description」の記述を追加しています。

  before_action :authenticate_user!, except: [:show]

  end

  def new
    @room = current_user.rooms.build
  end

  def create
    @room = current_user.rooms.build(room_params)
    if @room.save
      redirect_to listing_room_path(@room), notice: "保存しました。"
    else

    new_params = room_params.merge(active: true) if is_ready_room
    if @room.update(new_params)
      flash[:notice] = "保存しました。"
    else
      flash[:alert] = "問題が発生しました。"
    end
    redirect_back(fallback_location: request.referer)

    @room = Room.find(params[:id])
  end
  
  def room_params
    params.require(:room).permit(:home_type, :room_type, :accommodate, :bed_room, :bath_room, :listing_name, :summary, :address, :is_tv, :is_kitchen, :is_air, :is_heating, :is_internet, :price, :active, :description)

end

リッチテキストの中に画像をアップロードするにはアマゾンS3のアクセス許可の設定をしなければなりません。
アクセス許可のタブの下部にある「Cross-Origin Resource Sharing (CORS)」の項目に以下の記述を追加して保存します。

[
    {
        "AllowedHeaders": [
            "*"
        ],
        "AllowedMethods": [
            "PUT",
            "POST",
            "DELETE"
        ],
        "AllowedOrigins": [
            "*"
        ],
        "ExposeHeaders": []
    }
]

画像のアップロードはこれでできるのですが、表示させるには「mini_magick」と「image_processing」をインストールする必要があります。
GemFileに以下の記述を追加して下さい。
