similar to: encrypting databases

I am pondering the possibility of encrypting/decrypting some fields in a SQLite backend on-the-fly. The point of the message is not security, I know that''s broken, but whether there''s a technique that provides on-the-fly save/read filters. Of course the solution would need to work transparently in joins, so user.posts.last.title would do the right thing if title

Hi all ! I''m having an issue and I can''t seem to make heads or tails of it. I am attempting to add an observer to a model object. I created app/models/greenback_transaction_observer.rb, inherited from AR::Observer, defined methods, registered in config/environment.rb, but things don''t work... So, I took a step back and put in the following code: class

Hi, In the pragmatic rails book, a password is hashed and saved using the callback before_create. To do this it sets up an accessor called ''password'' and saves the SHA1 output in the backend as ''hashed_password''. I''ve done a similar thing, but instead of using an accessor I simply use ''password'' for both and assign using: def

Hello, I am still reading Agile Web Developer pdf, it says about after_initialize and after_find. There is a Joe asks part when I read that they are special, however I didn''t really get the idea, why they are. On rubyonrails.org in the manual there is some sort description about their speciality, however their full descriptions are missing. What are the difference between

Hi there I''ve been running BackgroundRb in production for a few months now. Recently we added encryption onto some of our ActiveRecord fields by hooking in the before_save and after_save callbacks, like: class MyCallback def initialize(attr_names) @attr_names = attr_names end def before_save(model) @attr_names.each do |attr_name| next if

Hi Railers, I''m looking for something to do asynchronous encryption - where the encryption and decryption keys are different. This is for a scenario where I want to be able to store some information in the database that can only be decrypted in a different physical location using a secret private key (which will not be stored on the machine doing the encrypting). I''m trying

Ask and ye shall receive. 1.1.3 now has a plugin test. i had one small issue with after_save being called, so i added the callback in. it works when i create a test app and run the unit tests so i think it has something to do with how i override the save method. if you have any suggestions, please feel free to comment. As far as the AR test suite goes...I''m not sure how this plugin

I am looking at adding the Sentry plugin to one of the applications that we are working on. I have a need to store some info that will have to be encrypted and decrypted. I have been going through the docs for the plugin and the AsymetricSentry class looks like the best for what we need to do but I am not sure how to generate the key. The docs say: This is a shortcut for using an

I try to understand the following issue : - when creating a new User record, I use an UserObserver to trap the before_save call back and send an email def after_create(user) UserNotifier.deliver_signup_notification(user) end - Once created a user can ask for a password reset, which is also trapped by the UserOberver def after_save(user) UserNotifier.deliver_reset_password(user) if

I have a Production model, which represents a farmer''s crop. After create (via after_save) I call a method that creates one or more Supply models, which represent a week of anticipated product harvest. After each of those are created, a class method gets called that tries to match each new Supply with outstanding orders for the same time period. If a match is made, a transaction (an

Hi, I am thinking about writing an acts_as_fox plugin that defines an after_find callback method. If I do this what will happen if a user creates a model that acts_as_fox but this model has it''s own after_find callback method? I imagine that the model''s after_find method shadows the plugin''s after_find. Presumably both after_find callbacks would need to be performed but

Hi, Very quickly, I''m having trouble calling my before_save ro before_update callbacks when I do something like User.update(id, params["user"]). I notice that Rails is calling after_save but for some reason it doesn''t call the before_save or before_update callbacks. Any thoughts would be appreciated. Thanks. -- Posted via http://www.ruby-forum.com/.

I am trying to add custom logging to my rails app via a ''.rb'' module file in the ''/lib'' directory and then call it from my models via CallBacks (ie: before_save, after_save, etc). It loads the module just fine in my class and the CallBack executes the module''s code. However, my module (remember it''s in the ''/lib''

If I wanted to update an attribute with calling any validation or any of the before_save and after_save hooks, how would I go about doing this? Supposed the update_attribute method calls the before and after save methods. Thanks for your help. -- Posted via http://www.ruby-forum.com/.

Is there a way to determine if attributes were changed? Let''s say in the before_save or after_save method? Thanks for your help.

So I have this key information that I got by generating a private and public key in VB, but it gave it to me in the form of a modulus and exponent in an XML file. Now, I need to encrypt some stuff in ruby using that info. On this site: http://blog.internautdesign.com/2007/11/2/ruby-openssl-rsa-public-key-from-modulus-and-exponent/comments/165, they explain how to do that, but clearly this info is

There''s a small inconsistency in ActiveRecord''s callback syntax that has tripped me up before. It wouldn''t be a big deal, but it can lead to a silent failure. I''d like to suggest that it either be made consistent or be made to fail loudly. The issue is that to do something before validating, but only when creating, you use `before_validation on: :create`,
