载波默认store_dir

Question

默认情况下，Carrierwave会应用以下上传器路径：

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

我想知道将model.id放在mounted_as之前是否存在任何错误：

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

所以例如：

uploads/user/123/avatar

与

相比，

是合法的路径

uploads/user/avatar/123
