Ruby on rails 使用carrierwave上载音频文件

我在上传carrierwave gem的音频时遇到问题，当我发布音频文件时，所有显示的都是音频url链接。第一次使用gem，不确定我是否正确使用carrierwave。只是尝试在显示页面上显示音频文件

  class AudioUploader < CarrierWave::Uploader::Base

  # Include RMagick or MiniMagick support:
  # include CarrierWave::RMagick
  # include CarrierWave::MiniMagick
  storage :file
  include CarrierWave::Audio

  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

end

音乐控制器

class MusicsController < ApplicationController
  before_action :set_music, only: [:show, :edit, :update, :destroy]

  # GET /musics
  # GET /musics.json
  def index
    @musics = Music.all
  end

  # GET /musics/1
  # GET /musics/1.json
  def show
  end

  # GET /musics/new
  def new
    @music = Music.new
  end

  # GET /musics/1/edit
  def edit
  end

  # POST /musics
  # POST /musics.json
  def create
    @music = Music.new(music_params)

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

    def music_params
      params.require(:music).permit(:title, :audio)
    end
end

class MusicsController

将url放入

标记中如何？这将是

@maxpleaner刚刚尝试了它创建的音频文件，但只有3秒钟，没有声音playing@maxpleaner好的，我刚刚上传了另一个音频文件，它可以正常工作。谢谢，@jmike和maxpleaner，我在rails项目中实现了这个功能，有了您的问题的帮助：）这不应该被标记为已回答吗？
