Rails - Jul 2009 - File upload

Hello. I''m new with Rails and I''m trying to create a file
upload app.


I want to make that it stores the file in public/data, that only .swf
files can be uploaded and that the filename in my server is the same
from the form (see below).

I currently have these files and want to integrate the upload to that
form, but I don''t know how to do that.

Thank you,
Gabriel.

---------------

class SfilesController < ApplicationController
	 def new
		 @sfile = Sfile.new
	 end

	 def create
		 @sfile = Sfile.new(params[:sfile])
		 respond_to do |format|
			 if @sfile.save
				 flash[:notice] = ''File was successfully created.''
				 format.html { redirect_to(@sfile) }
			 else
				 format.html { render :action => "new" }
			 end
		 end
	 end

	 def show
		 @sfile = Sfile.find(params[:id])
	 end
end

--------------

class Sfile < ActiveRecord::Base
	 validates_presence_of :title
end

----------------

<h1>Welcome</h1>

<% form_for(@sfile) do |f| %>
  <%= f.error_messages %>

  <p>
    <%= f.label :title %><br />
    <%= f.text_field :title %>
  </p>
  <p>
    <%= f.label :description %><br />
    <%= f.text_area :description %>
  </p>
  <p>
    <%= f.submit ''Create'' %>
  </p>
<% end %>

hum, the question is the file it''s represented in a model?anyway, i
used
virtual attributes...
any questions, just ask =)

at sfile.rb

validate_on_create :validate_upload

def temp_file= temp_file
   @temp_file = temp_file
end

protected

def validate_update
    errors.add_to_base("Upload a valid Flash file") unless
validate_type_file @temp_file
end

def validate_type_file file
    original_filename = file.original_filename
    extension = SFile.ret_ext_file original_filename
    reg_file = Regexp.new(/(flw)/)
    if n =~ reg_file
      return true
    else
     return false
   end
end

def self.ret_ext_file n
    v = n.split(''.'')
    v = v[v.size-1].downcase
    return v
  end


at .erb

<h1>Welcome</h1>

<% form_for(@sfile) do |f| %>
 <%= f.error_messages %>

 <p>
   <%= f.label :title %><br />
   <%= f.text_field :title %>
 </p>
 <p>
   <%= f.label :description %><br />
   <%= f.text_area :description %>
 </p>
  <p><%= file_field ''i'',
''temp_file'' %></p>
 <p>
   <%= f.submit ''Create'' %>
 </p>
<% end %>

at sfile_controller.rb

def create
                @sfile = Sfile.new(params[:sfile])
                @sfile.attributes = params[:i]
                respond_to do |format|
                        if @sfile.save
                                flash[:notice] = ''File was successfully
created.''
                                format.html { redirect_to(@sfile) }
                        else
                                format.html { render :action =>
"new" }
                        end
                end
end
