similar to: Why no call to Model.new on find?

Hi everybody I would like a function as the "before_save" method in the model. But it must be the opposite. When I take out data from the database through the model, I want to call a function before the data are available in the controller. Can anyone help me? ---- >>>> thx <<<< ---- -- Posted via http://www.ruby-forum.com/.

Nothing special, just my first plugin. it came out of a request I saw on the list from someone who wanted to be able to tell if a model''s attributes had changed prior to being saved. Well, this plugin does just that (at least I hope it does). http://rubyforge.org/projects/actsasmodified/ Please see the README for details. Constructive comments and criticisms are appreciated. Chris

After a couple of thoughtful comments, I''ve made changes to acts_as_modified plugin. It no longer relies on after_find and after_initialize, which were both causing performance issues. Please check it out and let me know what you think, where you might recommend improvements or additional features and what not. One feature I do have planned (again, thanks to comments), but

Hi, I know that it is possible to execute code each time data is saved into a model by using the +validate+ method. However, is there also a way to execute code each time the data is accessed, not just when it is changed? Bye, Winsmith -- Posted via http://www.ruby-forum.com/.

I want to expire caches if a certain field of an item changes. How can I compare the item field''s old value to its new value (in the create, or after_save, etc. method)? thanks csn __________________________________ Yahoo! Mail - PC Magazine Editors'' Choice 2005 http://mail.yahoo.com

Hi! I got a class named EinsatzFilter which I serialized to session. Before saving to session it works afterwards I keep getting the message: "undefined method `to_s'' for #<Person:0x38c6ab8>". "Person" is a from ActiveRecord::Base inherited class. Code: class EinsatzFilter include ApplicationHelper attr_reader :personen, :monat, :projekte, :kunde

Hi, I have a user model with an e-mail field. When a user registers for the site, I want them to confirm their email address by typing it in again. If they change their email address, I want them to confirm their email address by typing it in again. However, the user might change things on their account not related to their email address, such as their phone number, and they should not have

Hey, I''m new, so apologies if I''ve overlooked obvious resources or violated any etiquette rules for this list. Since rails does not support the MySQL enum data type, I''m following David''s advice of using a varchar and storing the valid values in the application: http://one.textdrive.com/pipermail/rails/2005-January/001536.html So here''s my

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

All, I''m wanting to initialize an ActiveRecord object. I understand that there is a method called after_initialize that appears to get called right after the ActiveRecord object is instantiated. Is after_initialize a Ruby thing or a Rails thing? Where is after_initialize documented? Can I pass parameters to it? If so, how? I want to initialize the "belongs_to" attribute of

I have 2 distinct types of users (artists and curators) in my system and they currently share all associations (eg has_one :portfolio). However, a curator shouldn''t have a portfolio so I would like to only add that association when required. Obviously I could just return nil for that method, but it doesn''t feel right having that there in the first place. What''s the best

Hi, I''m using activemerchant and setting up a class variable using config.after_initialize. It works great for the first request, but then the variable is nil. config.after_initialize do ActiveMerchant::Billing::Base.mode = :test OrderTransaction.gateway = ActiveMerchant::Billing::PaypalGateway.new(...) end I''m assuming this is is due to the model reloading after each

Question for all: Right now i have a Table in a mySQL DB that has a row called Ingredients. When the data is entered into the DB its enter like so from a text area: 1 1/2 lbs. beef top sirloin, thinly sliced 1/3 cup white sugar 1/3 cup rice wine vinegar 2 tablespoons frozen OJ concentrate 1 teaspoon salt 1 tablespoon soy sauce 1 cup long grain rice 2 cups water 1/4 cup cornstarch 2 teaspoons

All, I have a quick question - is the purpose of implementing after_initialize to allow custom attribute initialization for AR descendants? I have been overriding initialize whenever I require custom setup of my model classes, like so: def initialize(attributes = nil) super self.Status = ''G'' end So I have a couple of questions: 1) Could I achieve the same

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

I''m trying to create a sequence with no gaps in my db (contrived example, but should work out the same as my real one), and believe db-managed transactions are the way to go about this. It''s my first real ''go'' at transactions, so I may be mistaken about how things really work. Anyway.. Consider this example code: Class Invoice < ActiveRecord::Base def

Wine always give errors when it tries to start on xser ver ":1" because it always tries to connect to ":0.0". I know that DISPLAY is set correctly: Xlib: connection to ":0.0" refused by server Xlib: Client is not authorized to connect to Server

We have a fairly expensive task that we''d rather not schedule too many instances of in parallel. Couldn''t get pool_size to limit the amount of workers, and I figure that''s hardly optimal anyway, so would like to have the work queued up for a single named worker instead, running as soon as possible. Using MiddleMan.schedule_worker() with :job_key does start off a

Good day, does anyone here have a clue on how to make use of the NoSQL database "Riak" with Camping? I am building my website and Riak seems like pretty much the ultimate database! This would probably ruin every little feature in ActiveRecord, I don''t think I''d be able to do any has_many''s or belongs_to but I''d LOVE to be proven wrong. As far as
