CarrierWave出错，上传旧文件

我在我的应用程序Carrierwave中使用上传声音。CarrierWave出错，上传旧文件

但是我有一个错误，如果我选择上传的声音，但它是错误的声音，如“toto.mp3”，所以我重新选择其他声音，如“titi.mp3”。当我现在上传我的声音时，我的应用程序中的文件是所选的第一个声音，所以是“toto.mp3”，但我选择“titi.mp3”而不是“toto.mp3”。

我不知道如何解决这个错误，如果你可以帮忙。

上传

# encoding: utf-8 
require 'carrierwave/processing/mime_types' 

class SoundUploader < CarrierWave::Uploader::Base 
    include CarrierWave::MimeTypes 

    # Choose what kind of storage to use for this uploader: 
    storage :file 
    # storage :fog 

    # Override the directory where uploaded files will be stored. 
    # This is a sensible default for uploaders that are meant to be mounted: 
    def store_dir 
    "#{Rails.root}/tmp/files/#{model.user_id}/#{model.id}" 
    end 


    def extension_white_list 
    %w(3ga 3gp 3g2 3gpp 3gp2 m4a m4b m4p m4v m4r mp4 aac flac flv avi asf wma wmv dpx mkv mka mks bwf mpg mpeg mp1 mp2 mp3 
     m1v m1a m2a mpa mpv rm mov ogm ogg ogv oga ogx nut riff webm weba wav mxf asx ts aiff aif aifc au snd caf) 
    end 

    # Override the filename of the uploaded files: 
    # Avoid using model.id or version_name here, see uploader/store.rb for details. 
    def filename 
    model.title = original_filename if model.title.to_s == '' 
    "#{secure_token}.#{file.extension}" if original_filename.present? 
    end 

    protected 
    def secure_token 
    var = :"@#{mounted_as}_secure_token" 
    model.instance_variable_get(var) or model.instance_variable_set(var, SecureRandom.uuid) 
    end 
end

而且我的javascript：

$(function() { 
    $('#new_sound').fileupload({ 
     dataType: 'script', 
     dropZone: $('#new_sound'), 
     acceptFileTypes: /(3ga|3gp|3g2|3gpp|3gp2|m4a|m4b|m4p|m4v|m4r|mp4|aac|flac|flv|avi|asf|wma|wmv|dpx|mkv|mka|mks|bwf|mpg|mpeg|mp1|mp2|mp3|m1v|m1a|m2a|mpa|mpv|rm|mov|ogm|ogg|ogv|oga|ogx|nut|riff|webm|weba|wav|mxf|asx|ts|aiff|aif|aifc|au|snd|caf)$/i, 
     limitMultiFileUploads: 1, 
     add: function (e, data){ 
      var file = data.files[0]; 
      var filetype = $(this).fileupload('option', 'acceptFileTypes'); 
      if (filetype.test(file.name)) { 
       $('#title').val(file.name); 
       $('#select_file').css('color', '#00A300'); 
       $('#send_file').css('display', 'inline'); 
       $("#send_file").on('click', function() { data.submit(); }); 
       $("#stop_file").on('click', function() { 
        $('#progress_file .bar').css('width', '0%'); 
        data.abort(); 
       }); 
      } 
      else { 
       alert('Format de fichier non supporté.'); 
      } 
     }, 
     progress: function (e, data){ 
      var progress = parseInt(data.loaded/data.total * 100, 10); 
      $('#progress_file .bar').css('width', progress + '%'); 
     }, 
    }); 
});

分享您的上传。 – cortex

我想我看到错误在哪里，错误是在我的JavaScript。我给你我的上传和我的javascript –

我找到了错误，我修复它 –

我找到了这个错误，只是在JS我删掉就行了：limitMultiFileUploads：1，而现在的工作。 :)

以前

$('#new_sound').fileupload({ 
     dataType: 'script', 
     dropZone: $('#new_sound'), 
     acceptFileTypes: /(3ga|3gp|3g2|3gpp|3gp2|m4a|m4b|m4p|m4v|m4r|mp4|aac|flac|flv|avi|asf|wma|wmv|dpx|mkv|mka|mks|bwf|mpg|mpeg|mp1|mp2|mp3|m1v|m1a|m2a|mpa|mpv|rm|mov|ogm|ogg|ogv|oga|ogx|nut|riff|webm|weba|wav|mxf|asx|ts|aiff|aif|aifc|au|snd|caf)$/i, 
     limitMultiFileUploads: 1,

后

$('#new_sound').fileupload({ 
     dataType: 'script', 
     dropZone: $('#new_sound'), 
     acceptFileTypes: /(3ga|3gp|3g2|3gpp|3gp2|m4a|m4b|m4p|m4v|m4r|mp4|aac|flac|flv|avi|asf|wma|wmv|dpx|mkv|mka|mks|bwf|mpg|mpeg|mp1|mp2|mp3|m1v|m1a|m2a|mpa|mpv|rm|mov|ogm|ogg|ogv|oga|ogx|nut|riff|webm|weba|wav|mxf|asx|ts|aiff|aif|aifc|au|snd|caf)$/i,
