Problems importing a CSV file using FasterCSV


I'm new to Rails, and I figured out how to export the results from my database, but I'm having trouble creating new records from a CSV file. With the code below, I want to be able to import a CSV file and populate the last two columns with session data from the user. For now, I just inserted a static number to try to get this to work. I am currently receiving "Unable to convert ActionDispatch :: Http :: UploadedFile to String" as an error message

DOCUMENT CSV

name, tasks, expected_results, require_id Name of test 1, Open file, Open, t Name of test 2, Read file, Read, t Name of test 3, Close file, Close, f

CONTROLLER

  def csv_import  
    file = params[:file]  
    FasterCSV.foreach(file,{:headers => true, :row_sep => :auto}) do |row|  
        Script.create!(:name => row[0],  
                      :task => row[1],  
                      :expected_results => row[2],  
                      :require_id => row[3],    
                      :department_id => 1,  
                      :category_id => 1)  
    end  
  end

VIEW

<%=form_tag '/script_admin/csv_import', :multipart => true do%>
<%= file_field_tag "file" %><br/>
<%= submit_tag("Import") %>
<% end %>

DB MIGRATION

class CreateScripts < ActiveRecord::Migration
  def self.up
    create_table :scripts do |t|
      t.integer     :department_id,       :null => false
      t.integer     :category_id,         :null => false
      t.string      :name,                :null => false
      t.string      :task,                :null => false
      t.string      :expected_results,    :null => false
      t.boolean     :require_id,          :null => false,   :default => "t"
      t.timestamps
    end
  end

  def self.down

drop_table :scripts

end end
