File upload

Rails
1

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

Welcome

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

<%= f.label :title %>
<%= f.text_field :title %>

<%= f.label :description %>
<%= f.text_area :description %>

<%= f.submit 'Create' %>

<% 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
