Having issues importing a CSV File using FasterCSV - ruby-on-rails-3

Question

I am new to Rails and I have figured out how to export results from my Database but I am having issues creating new records from a CSV File. With the code listed below I want to be able to import a CSV file and fill in the last two columns with session data from the user. For now I just inserted a static number to try to get this working. I currently receive "can't convert ActionDispatch::Http::UploadedFile into String" as the error message
CSV DOCUMENT
name,task,expected_results,require_id
Test Name 1,Open a File,Open,t
Test Name 2,Read a File,Read,t
Test Name 3,Close a 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
Any help with this can be appreciated

Issue is resolved thanks to James Gray
def csv_import
file = params[:file]
FCSV.new(file.tempfile, :headers => true).each 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
