similar to: <model>.update(...) not calling before_update callback.

Hey guys, I''m having a hard time w/ the after_update callback on rails... As far as I can tell, when I define a after_update callback on a model, the attributes of the object have the same values that they had *before* Base.save was called. I''m probably wrong so here''s the code: UNIT TEST: def test_register_item_adjusts_account_balance account =

With after triggers in Postgres, there are special NEW and OLD vars accessible to trigger functions. Any such thing in Rails? Or would it entail doing something like setting a class var in before_update? Jack -- Posted via http://www.ruby-forum.com/.

What''s the better thing to do in a before_save if you don''t want the save to continue? raise an exception, or do an errors.add or both? Thanks, Chris Nolan.ca http://kweschun.com/ - Do you have a Kweschun?

Any thoughts on this one guys? How do I reinitialize an already initialized model object in my controller in one shot rather than manually initializing each attribute? In other words, I do a find like so: user = User.find(id) # Now I want to reinitialize the user object by using the params["user"] but I''d like to intialize it in a way that calls my model''s equality

I''d like to be able to enable/disable the automatic indexing of documents acts_as_ferret does. Something like MyModel.disable_indexing MyModel.enable_indexing would be perfect. I need this because I do some indexing that requires visiting the parents of the model objects and my import method imports the children first, so the information isn''t there yet. I''d like to

In one of the models I perform some operation. For simplicity let''s assume that I populate column ''b'' with column ''a'' * 2. def before_update self.b = self.a * 2 end In my fixture I set values for a. first: id: 1 a: 10 Whe I run the test before_update is never invoked when rails populate the test table with the data from fixture. In

In the Rails Recipes book the recipe "Keeping track of who did what" explains how to do decoupled observing of models. In my application I''d like to do a similar thing but watching the controllers. For example, when somebody hits the login method of the Security controller, I''d like to make a note of it. In this case I could observe the User model and watch for

Hi I have an problem about before_* callbacks. I have a model named: Event And I don''t want anyone to destroy or update any records in Event model. So: [code] class ActiveRecord::Base before_destroy :log_illegal_operations before_update :log_illegal_operations private def log_illegal_operations Event.create({:key => "illegal operation", :value =>

Don''t know why, but cant seem to get this to work for me. I have a phone number field for an addressbook. In the addressbook model I have a before_update declaration that says the following: I''d like to be able to remove all special characters (just numbers please), but this doesn''t want to work for me. before_update :format_phone def format_phone self.phone =

hi, i''m just getting started using switchtower for deployment. i''m working with a small team of 3 and a hosted subversion repository. i have switchtower working, but i need to create two custom tasks and have those tasks run at deployment. 1) copy a working dispatch.fcgi from another folder, and 2) copy db/database.example to db/database.yml here is what i''ve tried,

Hi all, here is the challenge: I have this validation method, that basically prevents an object which billed = true to be updated: def before_update if read_attribute(:billed) errors.add_to_base(''This service has already been billed for'') end !read_attribute(:billed) end The above code does not work in case I do something like: object =

I have a new @offer that needs to generate a document if saved. But that''s all or nothing: transaction do @offer.save! generate_document end # handle exceptions if needed If save! fails everything is fine, but if generate_document raises an exception @offer is left as a model with timestamps, id, which is not a new_record? anymore (though the database was

I have a User class with a field called admin which is a boolean that determines if the user is or is not an administrator. I want to make it impossible for the last administrator for an account to be removed from the system. I need to protect against this both when deleting a user and when editing a user as you can revoke a user''s administrator privileges via a form. User

Hi all, I''ve add :before_update event to my model Before updating a record I want to check if new attributes differ to old attr. My question is how to retrieve old attributes in :before_update event ? thanks -- gratis egold 1$ http://shegold.com/

Hi all - To avoid floating point issues, I''ve decided to store monetary values in cents in the database. However, the user will enter these in dollars and cents. Two questions: 1) How do I do the validation for the currency format? It looks like ActiveRecord truncates the cents since it thinks the field type is a Fixnum. Am I forced to do validation in the controller? 2) Where

Where can I find more information about the new syntax on these: <%- model_class = @product.class -%> <h1><%=t ''.title'', :default => t(''helpers.titles.new'', :model => model_class.model_name.human, :default => "New #{model_class.model_name.human}") %></h1> <%= render :partial =>

Hi, I was wondering if anybody knew what ''<some type> expected, got Fixnum'' means? My code looks like the following: begin anevent = Event.new anevent.title = params["event"]["title"] anevent = session[:user_id] com = Community.find(params[:id]) com.events << anevent rescue Exception => exc ... end But I get an

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

I''m trying to get a collection_select generated Drop-down box to display two fields from a table (first name & last name); however, I am having trouble concatenating the symbols. It appears as though any code I put in the 5th argument for collection_select is processed prior to executing the collection_select method. The code executes successfully with 1 symbol in the 5th

I''m doing very well with the Hibbs Rolling on Rails tutorial. I have an easy question for my personal notes. I''m coming up with a simple framework of steps for creating a basic database. It includes the following maxims to make original app creation easy: app_name = MySQL database name SQL_tablename = model_name model_name = controller-name Is this going to work for getting
