Howtos: Upload a file through Ruby

[Bala]

Experts,

I'm trying to upload a file through ruby code. i tried docs.upload
through
but it always says you have to upload through Multiform/POST.
Even i tried with http://stackoverflow.com/questions/184178/ruby-how-to-post-a-file-via-http-as-multipart-form-data
but still i have no luck,

My View Code

<form name="upload_form_scribd" enctype="multipart/form-
data" method="POST" action="/scribd_upload_data"
target="upload_target" method="post" onsubmit="new Ajax.Request('/
scribd/upload_data', {asynchronous:true, evalScripts:true,
onComplete:function(request){Element.hide
('progress2_id')},onLoading:function(request){Element.show
('progress2_id')}, parameters:Form.serialize(this)}); return false;">
<% form_remote_for(:upload_target, :url => {:action =>
'upload_data'}, :loading => "Element.show('progress2_id')", :success
=> "Element.hide('progress2_id')",:html => { :multipart => true }) do |
f| -%>
<div class="column">
<div class="label">Browse</div>
<div class="form-field-content"><input type="file"
name="file_by_browse" id="title_field" class="text-field" value=""></
div>
</div>
<div class="column">
<div class="label">Title</div>

Hi there,

Did you look at the rscribd gem? Doing multipart POSTs in ruby can
indeed be tricky, and the rscribd gem already has a working
implementation.

Hi Jared,

yeah i tried initally but my clients requirement to use Javascript API
and that too, we had loads of issue while installing gems, we were
more concern
with version.

Thanks,
Bala
