Question

请帮助解决问题

使用表格我上传文件：

<%= form_for(@video) do |f| %>
  <%= f.text_field :title %>
  <%= f.file_field :video %>

  <%= f.submit %>
<% end %>

控制器：

  def create
    p '============'
    p params[:video][:title]
    p params[:video][:video]
    p params[:video][:original_filename]
    p params.inspect

    redirect_to root_url
  end

  def video_params
    params.require(:video).permit(:title, :video, :original_filename)
  end

我需要带到控制台：

p params[:video][:original_filename]

但是控制台没有出现original_filename：

请试试这个

 p params[:video][:video].original_filename

如何下载文件并获取其名称？
