Dear all,

I have a doubt, iam not getting the uploaded file when iam uploading  
using ajax form like,

\<% remote\_form\_for(:videos, :url =\> {:controller =\> :videos, :action  
=\> :add },  
:html =\> { :multipart =\> true, :ajaxupload =\> true }) do |form| %\>

File \<%= form.file\_field :uploaded\_data %\>

\<%= submit\_tag “uploadfile”%\>

In controller when i call

params[:videos][:uploaded\_data], iam getting a string like filename  
\<sample.gif\>

but i was not able to reterive the uploadedfile and when i call methods  
like

params[:videos][:uploaded\_data].original\_filename,  
params[:videos][:uploaded\_data].read iam getting errors.

So could anyone please suggest how to perform file uploading using ajax.

Thanks in advance

Regards,  
Martin

I don’t think it’s possible to upload files with AJAX, but there are  
some workarounds with hidden iFrames. It’s not very elegant, but it  
works.

See this, for instance:

Use LiveQuery then you don’t need rjs and responds\_to\_parent
