Ar-code attachment_fu

Guys,

I am having real troubles uploading documents into the database correctly. The aim is to be able to upload PDF, MS Word and Plain text files and store them in the database.

Given my problems it may be needless to say, I am using this on Windows and unfortunately, it looks like the site will be deployed with IIS (yuck!).

The data BLOB size for any of the uploaded documents in the db_files table is showing the incorrect size (i.e. only a part of the file seems to be uploaded) whereas the associated model shows the correct filesize.

Smaller text files and some smaller Word documents (less than 50K) are uploaded correctly whereas larger files seem truncated. This results in a corrupted file message for PDFs and for MS Word, the usual MS Office magic of trying to install some extra bits of software!

There is no particular size boundary at which this happens. I uploaded a certain 48K Word document with no problems whereas another 33K Word document doesn't make it (only 15K of it is stored in the BLOB).

I got the plugin working (insofar as it does) after applying the sleep x workaround for windows.

I have attempted the other fixes such as modifying tempfile.rb, and the various changes suggested within attachment_fu.rb but to no avail.

My code was simple enough (thanks to wonderful resources out there esp. Mike Clark's)

In the document model:

class Document < ActiveRecord::Base
  has_attachment :content_type => ['application/pdf', 'application/msword', 'text/plain'],
                 :max_size => 2.megabytes
  validates_as_attachment
  
  belongs_to :project
  has_many :topics
end

In the controller:

  def documentupload
    sleep 1 #this is here 'cause windows doesn't handle files well
    @document = Document.new(params[:document])
    unless @document.save
      flash[:notice] = 'document could not be saved'
    end
    redirect_to :action => 'show', :permalink => @project.permalink
  end

In the view:

<%= error_messages_for :document %>
<% form_for(:document, :url => { :action => 'documentupload', :id => @project.id}, 
							:html => { :multipart => true }) do |f| %>
<fieldset>
<p>
	<%= f.file_field :uploaded_data %>
</p>
<p>
	<%= submit_tag 'Upload' %>
</p>
</fieldset>
<% end %>

All the examples out there only talk about image files; hopefully, someone has implemented this for the file types I'm attempting here.

Thank you
