我在我的应用程序中使用 Carrierwave 来上传声音。
但是我有一个错误，如果我选择一个声音进行上传，但它是错误的声音，如“toto.mp3”，所以我重新选择了其他声音，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”，但我选择了“titi.mp3”而不是“toto.mp3”。
如果您能提供帮助，我不知道如何解决此错误。

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

# storage :fog
# Override the directory where uploaded files will be stored.

"#{secure_token}.#{file.extension}" if original_filename.present?
end

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

还有我的 Javascript：

dropZone: $('#new_sound'),

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 () {

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