我打算使用 Rails 将我的应用程序部署到 Heroku。但是我从 Heroku 日志文件中得到了这个错误。

ENV 是 C9.io 和Rails 4.2.8, 而且我一直用它来找出它是什么错误。但是什么也没发生。

我尝试了ulimit -s ...更大堆栈大小的命令，但它不起作用。我也尝试了很多宝石bundle install，甚至bundle update，git push -f heroku master....但不起作用。

我在我的display_controller.rb.

class DisplaysController < ApplicationController
  before_action :set_display, only: [:show, :edit, :update, :destroy]
  before_action :authenticate_user!, only: [:new, :edit, :create, :update, :destroy]
  # GET /displays
  # GET /displays.json
  def index
    @display_list = Display.all
  end

  # GET /displays/1
  # GET /displays/1.json
  def show
    @display_list = Display.all
  end

  # GET /displays/new
  def new
    @display = Display.new
  end

  # GET /displays/1/edit
  def edit
  end


  def hashtags
    tag =Tag.find_by(name: params[:name])
    @displays= tag.displays
  end

  # POST /displays
  # POST /displays.json
  def create
    @display = Display.new(display_params)

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

  # PATCH/PUT /displays/1
  # PATCH/PUT /displays/1.json
  def update
    respond_to do |format|
      if @display.update(display_params)
        format.html { redirect_to @display, notice: 'Display was successfully updated.' }
        format.json { render :show, status: :ok, location: @display }
      else
        format.html { render :edit }
        format.json { render json: @display.errors, status: :unprocessable_entity }
      end
    end
  end

  # DELETE /displays/1
  # DELETE /displays/1.json
  def destroy
    @display.destroy
    respond_to do |format|
      format.html { redirect_to displays_url, notice: 'Display was successfully destroyed.' }
      format.json { head :no_content }
    end
  end

  def list
    # list.html.erb
    @lists=Tag.all
  end

  private
    def set_display
      @d = Display.find(params[:id])
    end

    # Never trust parameters from the scary internet, only allow the white list through.
    def display_params
      params.require(:display).permit(:title, :artist, :start_date, :end_date, :time, :address, :image, :description, :url, :content)
    end
end

有没有办法找到错误？
