Ruby on rails 使用Rails的载波多文件上传

我正在使用。它可以很好地处理单文件上传。 有没有办法使用相同的代码进行多次上传

我的模型：

class EmpDetail < ActiveRecord::Base
  mount_uploader :avatar, AttachmentUploader
  validates :emp_name, :avatar, presence: true
end

emp_detail/_form.html.erb：

<div class="field">
  <%= f.label :emp_name, :class => 'control-label' %>
  <div class="controls">
    <%= f.text_field :emp_name, :class => 'text_field' %>
  </div>
</div>

<div class="control-group">
  <%= f.label :avatar , :class => 'control-label' %>
  <div class="controls">
    <%= f.file_field :avatar, :class => 'file_field' %>
  </div>
</div>
<div class="form-actions">
  <%= f.submit "Create Emp Details", :class => 'btn btn-primary' %>
  <%= f.submit "cancel", method: :delete, data: { confirm: 'Are you sure you want to cancel' } %>
</div>

'控件标签'%>
'文本\字段'%>
'控件标签'%>
'文件\字段'%>
“btn btn主节点”%>

Carrierwave自述中的部分。阅读文档。有一个段落用于多个文件上载。

<div class="field">
  <%= f.label :emp_name, :class => 'control-label' %>
  <div class="controls">
    <%= f.text_field :emp_name, :class => 'text_field' %>
  </div>
</div>

<div class="control-group">
  <%= f.label :avatar , :class => 'control-label' %>
  <div class="controls">
    <%= f.file_field :avatar, :class => 'file_field' %>
  </div>
</div>
<div class="form-actions">
  <%= f.submit "Create Emp Details", :class => 'btn btn-primary' %>
  <%= f.submit "cancel", method: :delete, data: { confirm: 'Are you sure you want to cancel' } %>
</div>
