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:
# Setup pdf layout
pdf.select_font("Helvetica", { :encoding => "WinAnsiEncoding"})

How to restrict access to images by user?
Hi,
I have a some image files that belongs to some users. Only the owner of an
image should be able to see it.
How can I do that?
I don''t think I can use send_data, because I want the image to be displayed
on a "rendered" page. I don''t think I can place the images in the public
folder, because if some user can figure out the name of the image then he''ll

Asterisk PBX How-to Guide for Amazon EC2

PBX on EC2. It is based on months of testing and evaluating Asterisk on EC2.
It addresses all kinks and showstoppers that many people have experienced

rendering images dynamically
Hi,
I have a rails application where I respond to a request by fetching
image urls from various web api calls and need to display them as they
come available. I am able to display all the images once I get them
all, but that causes an unacceptable delay for my user.
One approach I am trying is, from my controller, set an @image

Self-referential many-many joins with :through
I thought I had this nailed but.. now I''m seeing spots..
I''ve included my models below, feel free to ignore them. I''m really
just after an example that works. I couldnt find one on the wiki...
which is fair enough considering Ricks patch:
http://dev.rubyonrails.org/changeset/4022 that fixed them only went
