quick send_data question...
Hi,
I am using send_data to allow users to download files from the database
but ran into a small problem, it seems that files upload fine but when
they download only 64kb of the file is sent.
I''m using the basic rails code from the Agile book:
#upload code in my sheet model
def file=(document_field)
self.filename = base_part_of(document_field.original_filename)

File_field and Firefox
Hi!
Im developing a simple prototype of an application. It fills an oracle
db with data about a file in the filesystem, and save the entire file
in a blob along with some metadata. To get the file in the db i use a

browser, but it doesnt work anymore in firefox. The problem is,
firefox seems to cut the pathname from the file.

Ouch! Can't figure out this file upload issue...
Okay, so this is driving me crazy. I''m trying to do a file upload
using code from a book.
What happens:
I get wrong number of arguments (1 for 0) in the upload controller
save action. No idea why.
Schema:
The schema for the picture model object is just a textfield named
comments and a binary field called data.
Upload controller:
def get
@picture =Picture.new

Problem with "can''t dump anonymous class Class"

the thread, so I''m starting over.

Document model with different subclasses for different types of documents.
With the code below, if I attempt to create a Document, it works fine, but

File.size() on Uploaded Images Fail
I am checking the file size of an uploaded file and storing it in a filesize
column. It will work just fine when the user uploads any files other than
images (jpg,png,gif).
Word, Excel, Powerpoint, .zip and more all work fine.
This is my model asset.rb that handles the file upload.
def newfile=(newfile_field)
self.filename = base_part_of(newfile_field.original_filename)

Rails File Upload w/ Ajax Update?
I''m trying to upload a file, display the upload progress and then
update a table with the newly uploaded file. Is there a way to
specify a :success handler for form_tag_with_upload_progress such that
I have access to the request.response data (in the way I can with
link_to_remote)?
The :finish JavaScript is being executed but because there is no

testing file uploads
Hi all,
I was wondering about the class used when rails receives file uploads.
Sometimes it appears to be a File, and other times it is a StringIO.
Also it has methods such as original_filename that don''t appear to
belong to either of these classes. I ask because I''m trying to work out
how to test my fil upload related models and controllers.
Is there some standardised way of

How to spec an attachment_fu model
First off, I''m not trying to spec attachment_fu, I know it''s been tested.
But, I added some code to that model that I do need to test. Basically,
I need to somehow fulfill the "uploaded_data" property so I can actually
run my tests(otherwise they fail because of validations). The
"uploaded_data" field is what would grab the multipart data from form.
