Rails - May 2010 - Problem using FasterCSV on Import: Can't convert Tempfile to string

Hi,

I''m trying to import a CSV file using fasterCSV and keep getting this
error when trying to import the file.

The parameters are passed from this view:

<% form_for :dump, :url => { :controller => ''mots'',
:action =>
''mot_csv_import'' }, :html => { :multipart => true } do
|f| %>
	<p>
		<%= f.label :file, ''Select file to import'' %><br
/>
		<%= f.file_field :file -%>
	</p>
	<p>
		<%= submit_tag "Submit" %>
	</p>
<% end %>

To this action:

  def mot_csv_import
    header_row = true
    row_number = 0
    FasterCSV.foreach(params[:dump][:file]) do |row|
      if not header_row
        Mot.create(
          :vrm => row[4],
          :is_active => 0,
          :is_new => 1)
        row_number += 1
        GC.start if row_number%50 == 0
        header_row = nil
      end
    end
    redirect_to :controller => ''mots'', :action =>
''index''
  end

Can anyone advise me where I''m going wrong, please?
