Basic File Question

I’m a data person and some of the basics on the front end seem to
escape me. I am merely trying to upload a file to the backend.
Everything works except that what is uploaded is not the file but the
reference to the file, i.e. #<File:0x57d79b8>

It’s got to be a simple thing I am missing…

This is the form

<% form_for(@workstmt,:url=>{:action=>‘create’},
:html => {:multipart=>true}) do |f| %>

Project name
<%= f.text_field :project_name %>

File name
<%= f.text_field :file_name %>

<%= f.text_field :sow_id %>

<%= f.file_field :workstmt %>

<%= f.submit "Create" %>

<% end %>

and the controller snippet is the default from the scaffold

def create
@workstmt =[:workstmt])
respond_to do |format|
flash[:notice] = ‘Workstmt was successfully created.’
format.html { redirect_to(@workstmt) }
format.xml { render :xml => @workstmt, :status
=> :created, :location => @workstmt }
format.html { render :action => “new” }
format.xml { render :xml => @workstmt.errors, :status
=> :unprocessable_entity }

This is the controller code that will work (with workstmt_file) being
the name of the file_field comng from the form

@workstmt =
@workstmt.file_name = params[:workstmt]
@workstmt.content_type = params[:workstmt]
@workstmt.workstmt = params[:workstmt][:workstmt_file].read
