Secret URLs and file downloads
I''m looking to do something similar to the "secret URLs" in Rails
Recipes, however, with file downloads. I want to avoid providing direct
URLs to people if possible.
I have files on disk in public/, so it would be good if each user got a
"unique" URL to each file that they are permitted to see (dealt with by
a user_id/file_id table). Then they are only allowed

send_data => invalid byte sequence in US-ASCII
I''m trying to display a generated .png plot via send_data(), but it
results in a server error "invalid byte sequence in US-ASCII" error.
I''m pretty sure this means that I need to specify the encoding
somewhere, but I haven''t been able to figure out where or how to do so.
Some particulars:

Buffer flushing
Short question: is there way to tell EM to actually send data after
send_data call?
I''m building a file transferring app. I send Mashal.dump''ed metadata
first, and then - the file contents (chunked). I found a silly bug:
receive_data() gets marshalled metadata and the first chunk of the
file in a single variable.
Like that:
c1.send_data("meta")

How to protect images from public?
Hi,
I''m trying to figure out the best way to protect images uploaded by
users who may wish to keep them private.
For example, if they are uploaded in the default file_column location
(/public/blah/blah/1/) then someone can simply type the URL
http://www.blah.com/blah/blah/1 and get the image.
I can store the images in a non-public directory in the rails app (ie:
/railsapp/images/X/)

Rails'' send_file, Mongrel, and *gasp* memory
I''ve had a right fun few days at work trying to figure out why our Rails
app (which isn''t under very heavy load) kept eating memory and bringing
our server to our knees. Eventually I traced it to send_file (which was
in a way a relief as it wasn''t down to my coding ;) -- every time a user
started downloading, the memory consumed by the app would jump, and

Sending a file *and* rendering a page
Anyone know how to send a file/data to the user agent (download it)
using #send_file or #send_data, *and* render a new page in the same
action?
This just sends the file and doesn''t render the page:
def gimme
...
send_data(our_data, :filename => ''output.csv'', :disposition =>
''attachment'')
end
And this will give a Double-Render error:

How to send data,
Hello,
First of all I''m new to working with sockets,
so the problems I''m having are probably because of my lack of understanding.
What I''m trying to accomplish is to create a mac os x client gui to ruby-debug.
When a application that includes ruby-debug is started,
it starts listening for 2 connections; 8989, 8990
The connection is made by calling the connectToApp

pdf/writer: table.render_on best practices?
Hi All,
I generate a pdf report that contains a table. The report is 14 pages, and
it takes 20s to be rendered. Most of these 20s are spend in the render_on
method. I wonder if it is possible to speed up that process?
To create the report, I do the following:
1) Setup pdf layout:

Offering downloads only to registered users
I''m writing an app for a blood exam center, where people can go and check
the results without going physically there. The customers log in the system
and a pdf download is offered to them. The downloads though will not be
stored in the db but in the filesystem.
How can I allow people to download files only if they''re authorised? I
obviously can''t store all the files in
