读取cookie时出现异常重新输入错误

Question

我正在尝试保存我的Quotation模型的ID并将其存储在我的控制器上的cookie中。但是当我尝试读取cookie时，rails会显示异常重新输入的错误。

class BasicsController < ApplicationController
  before_action :get_cookie

  def quotations
    if params[:quotation]
      @quotation = Quotation.new( params.require(:quotation).permit(:author_name, :quote, :category) )

      if @quotation.save
        flash[:notice] = 'Quotation was successfully created.'
        Quotation.new
      end
    else
      @quotation = Quotation.new
    end

    if params[:sort_by] == "date"
      @quotations = Quotation.order(:created_at)
    else
      @quotations = Quotation.order(:category)
    end
  end

  def get_search
    @quotations = Quotation.all

    if params[:search]
      @quotations = Quotation.search(params[:search])
    else
      @quotations = Quotation.all.order("created_at DESC")
    end
  end

  def cookies
    id = params[:id]
    @removed_id = [1, 2, 3, 4]
    cookies[:removed_id] = @removed_id
    redirect_to basics_quotations_path
  end

  private
  def get_cookie
    cookies.delete :test
    # @removed_ids = Array.new
    puts @removed_ids.to_s
  end
end
