file_column error: StringIO Instead of Temp_File

Hi all,

i am using file_column to upload 3 images from the same form, they are all different names and DOM IDs so there isn't a problem with the multiple upload. The problem is when i try to upload a file (or 2, or 3) sometimes it works, but sometimes i get this in the log file:

"bar_image"=>{"file_temp"=>"", "file"=>#<StringIO:0xb4b08268>}

and the picture is not saved.

the pictures i upload are 60x60 and there is no file_column validations or limitations at all. when uploading larger images (500x500 for ex.) it works.

anyone?

Hi. I am getting a similar problem.

I did an svn install of file_column in my vendor directory,

I have the following code in my model:

class FileUpload < ActiveRecord::Base   file_column :path end

"path" is :text db is mysql

in my controller:   def do_upload_file     fileRecord = FileUpload.new(:path => params[:path])     fileRecord.save     redirect_to :action => index   end

in the view: <%= form_tag ({:action => 'do_upload_file'}, {:multipart => true})%>

    <%= file_column_field "file_upload", "path" %>     <%= submit_tag "upload" %> <%= end_form_tag %>

The resulting html is

<form action="/info_upload/do_upload_file" enctype="multipart/form- data" method="post">

    <input id="file_upload_path_temp" name="file_upload[path_temp]" type="hidden" /><input id="file_upload_path" name="file_upload[path]" size="30" type="file" />     <input name="commit" type="submit" value="upload" /> </form>

That is exactly what I did and nothing else. When I upload the image the path field in the db is an empty string. It used to NULL but then I changed the column to be not null. The / path/tmp directory is created but there is no file in it.

I am guessing I am doing something really stupid because the plugin seems to work fine out of the box for most people.

Would appreciate any help.
