how to download a file and get its name?

Question

please help solve the problem

using form I upload a file:

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

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

controller:

  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

I need to bring to the console:

p params[:video][:original_filename]

but the console does not appear original_filename:
