Anyone know of a good (fast) way to encrypt/decrypt uploaded files in RoR? I''ve seen this project: http://ezcrypto.rubyforge.org/ but it only seems to encrypt strings and such. I need to encrypt files once they are uploaded, then decrypt them when they request the file back. Any ideas? Thanks, Mark -- Posted via http://www.ruby-forum.com/.

Hi All - I notice that most of the Rails team are using Mac OS X and TextMate for Ruby development. I too am working on Mac OS X and trying TextMate and (shudder?) EMacs. I was wondering about version control. Are folks using Subversion? If so, are they using a graphical client? Which one do they recommend? Yours, Jordan -- Posted via http://www.ruby-forum.com/.

Quick question to see how I might re-sort an Activerecord data set.

My

I just replied to someone about using send_file and while I was testing my solution I figured out that the controllers "current working dir" appears to be the root of the app. Then I saw a reply that Ezra sent to someone where he used RAILS_ROOT and I thought "duh, I''ve seen that before... shoulda used that". But, when I had an action print out RAILS_ROOT

image_tag(source, options = {}) Ok, when I want to use an image I added the following code: <%= image_tag "dsf.jpg" options = {[align="right", style="padding-right: 10px; padding-top: 5px;"]} %> However, this doesn''t seem to work, it doesn''t like how I have the "options" part setup. I''m sure there is something very easy

(Nuby to Ruby and Rails...) I''ve implemented security using the login generator in a simple app so that I have a user table, a roles table, and a join between them (roles_users). All works as expected. I now need to check if a user has a specific role, but my approach is off somehow. Here''s what I''ve tried thusfar: user_roles = @session[:user].roles

Hi all. I have two Rails applications. Each is on its own VPS hosted by Pipespring (excellent service btw). My app runs lightning quick - AFTER the first load. If I visit my site after a period of inactivity (i.e. no visitors to my site), it takes up to 10 seconds to load that first time. After that I can hop around with no problems. Has anyone run into this before? Ideas? - Rabbit

I have an error page defined in my .htaccess file and I''m in production mode. Sometimes I still get the Application Error (Rails) white page though. In this case there was a nil object that I tried to access in a controller without first checking if it was nil. How does Rails decide what error page to display and how can I get the pretty error page to display more often? Thanks.

I am confused about ruby fast C bindings. Does the command: gem install mysql install these? Is this page: http://www.tmtm.org/en/mysql/ruby/ the home page for these bindings? If so, it gives no instructions about installing them with using gem. Wondering if this is all the same??? Thanks for any help...

Hey, just put together a small swf movie of the app I''m working on. The first frame shows just a test frontend index page. The rest is all backend. I didn''t include showing what code gets generated etc as it would make the movie way too long. But figured some people might enjoy watching. http://mtvsucks.org/first_rapture.htm -Paul
