Question

我在我的应用程序Carrierwave中使用上传声音。

但是我有一个错误，如果我选择上传的声音，但这是错误的声音，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第一个选择的声音，所以是“toto.mp3”，但我选择“titi.mp3”而不是“toto.mp3”。

如果你能提供帮助，我不知道如何解决这个bug。

  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

  # 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

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 + '%');
        },
    });
});

我发现了这个bug，只是在JS中我删除了行：limitMultiFileUploads：1，现在就可以了。：）

<强>之前

$('#new_sound').fileupload({
        dataType: 'script',
        dropZone: $('#new_sound'),
