Rails - Jul 2006 - form_remote_tag with multipart/form-data

Does form_remote_tag supports multipart/form-data ?

My form looks like this:

<%= form_remote_tag :url  => { :action =>
''do_image_upload'' },
                    :html => { :enctype =>
''multipart/form-data'' } %>
<%= file_field ''image'', ''file_data'',
:size => 32 %>
<%= submit_tag ''Upload'' %>
<%= end_form_tag %>

and produces:

<form action="/home/do_image_upload"
enctype="multipart/form-data"
method="post" onsubmit="new
Ajax.Request(''/home/do_image_upload'', {asynchronous:true,
evalScripts:true, parameters:Form.serialize(this)});
return false;">
<input id="image_file_data" name="image[file_data]"
size="32" type="file">
<input name="commit" value="Upload"
type="submit">
</form>

but when I take it for a spin params[:image][:file_data] is nil.

None of the image uploading howtos I''ve read use form_remote_tag, is
this why?

Thanks for any insight.

What are you trying to do? When I came across this I set up an invisble 
IFrame. I used an ordinary form with a target which is the IFrame. Then 
I assembled a javascript response on the server which gets put in the 
IFrame and manipulates the browser window as I needed to.

I was using form_remote_tag because I need to run an RJS template
after the image upload.

Using an iframe had crossed my mind as a last resort.

do you have the output from the web-server as you try to submit the
form? the params appear there, so maybe that can give you a clue.

i use http://manuals.rubyonrails.com/read/chapter/79 (use google cache
if you get an error) and it works fine.

by the way, multipart is available as an option:
<%= start_form_tag ({:action=> "add"},  {:multipart => true})
%>

irb(#<HomeController:0x255f32c>):001:0> params[:image]
=> {"description"=>"dsfg",
"friendly_name"=>"sdfg"}
irb(#<HomeController:0x255f32c>):002:0> params[:image][:file_data]

Right.  But I''m trying to use form_remote_tag.

right. sorry
I have the same problem, and from the error page i can see that the 
file_data parameter isn''t passed to the server.

I tried using file_field_tag and passing it as a parameter out of image 
but the file_data just doesn''t get trough the form. Maybe this is a
bug?

doesn''t work for security reasons.

In Rails 1.1 (for me and for some others that I''ve read about) the
upload
portion of this works. Using a breakpoint also indicates that you get inside
of the RJS file. However, things like page.replace, page.alert, etc will not
work.
Does anyone have a fix for the plugin?
