attachment_fu content_type problem

Hi all....

Admittedly I''m new to Rails and trying to find my way but I''m
having
an issue with uploading documents with attachment_fu.

I have a form where I''m uploading multiple attachments (using AJAX to
add file_filed_tags).  That seems to work pretty well.  The problem is
I can''t seem to get the content_type to work as I would expect.  For
example, if I use this:

has_attachment :content_type => [''application/pdf'',
''application/
msword'', ''text/plain'']

I would expect I can upload .pdf, .doc and .txt files but I get and
Document is invalid error (document is the name of my model)  I have
played around with different content_types but I can''t seem to get
consistent results.

Thanks for any help.

- Mark

Here is the document model

class Document < ActiveRecord::Base
  belongs_to  :tournament, :polymorphic => true

  has_attachment :content_type => [''application/pdf'',
''application/
msword'', ''text/plain''],
                 :storage => :file_system,
                 :max_size => 1.megabyte

  validates_as_attachment

end

Re: attachment_fu content_type problem

I''m making some progress but I can''t figure out the error...

If I comment out this line in attachment_fu.rb my files upload but their file
size in the table is 0 (zero).  If i uncomment the code the upload fails with an
invail field error.  I have noticed that the code seems to work on small files. 
<16k

# validates the size and content_type attributes according to the current
model''s options
  def attachment_attributes_valid?
  [:size, :content_type].each do |attr_name|
  enum = attachment_options[attr_name]
##            errors.add attr_name,
ActiveRecord::Errors.default_error_messages[:inclusion] unless enum.nil? ||
enum.include?(send(attr_name))
  end
end

This is what I''m doing to upload the files

# Save the uploaded files
params[:documents].each do |doc|
@tournament.documents << Document.new(:uploaded_data => doc)
end unless params[:documents].nil?

Re: attachment_fu content_type problem

Well,

It doesn''t look the my issue had to deal with the content_type at all. 
Rather it was related to the size of the attachment.  Seems that for files <
about 16k, Attachment_fu handles them as a StringObject.  If they exceed 16k
they are stored as temp files which causes issues in windows.
